Question: I'm a zookeeper. What are the best enrichment toys and activities for large primates?
For large primates—especially gorillas, chimpanzees, bonobos, and orangutans—the most useful enrichment usually creates opportunities to forage, manipulate objects, climb, solve problems, make choices, and perform species-typical behaviors, rather than simply providing “toys.” Smithsonian’s National Zoo, for example, uses several enrichment categories and deliberately rotates activities to maintain novelty.
High-value enrichment ideas
Foraging puzzles: Heavy-duty feeder balls, perforated PVC tubes, puzzle boxes, hanging feeders, and containers that require manipulation or tools to access food. Vary difficulty and placement. Smithsonian keepers report using puzzle feeders and PVC tubes that encourage apes to use sticks as tools.
Scatter feeding: Spread portions of the normal diet through substrate, browse, platforms, or multiple enclosure locations rather than presenting everything in one place. This extends feeding time and encourages searching.
For large primates like chimpanzees, gorillas , and orangutans , the gold standard for enrichment isn't just about a "toy" they can hold—it's about cognitive challenge, processing time, and mimicking the complex, time-consuming foraging they would do in the wild.
Here are some of the best high-impact enrichment devices, structural setups, and interactive activities utilized across modern zoological facilities:
Cognitive & Foraging Puzzles
Multi-hole PVC pipes filled with seeds, pellets, or nuts hung vertically or horizontally. Primates have to use fingers, sticks, or wire tools to maneuver the food out bit by bit.

For large primates—especially gorillas, chimpanzees, bonobos, and orangutans—the most effective enrichment is usually behavior-driven rather than simply “more toys.” The current APV/ASP position statement emphasizes multimodal enrichment tailored to species and individuals, while AZA's behavior group specifically encourages moving from item-driven to behavior-driven and experiential enrichment.
High-value options
Complex foraging devices: Puzzle feeders, food-filled tubes, manipulable dispensers, and feeders that require pulling, turning, probing, or tool use. These can substantially increase activity and food-directed behavior in great apes.

ChatGPT Search· Sep 17, 2026
For large primates—especially gorillas, chimpanzees, bonobos, and orangutans—I’d prioritize enrichment that creates choice, foraging effort, manipulation, climbing/movement, and species-typical problem solving, rather than simply providing “toys.” Current primate-welfare guidance emphasizes variety and individualization, with observation used to determine what actually engages each animal.
For large primates (like chimpanzees, gorillas , and orangutans ), the best enrichment combines cognitive challenge, fine motor manipulation, and natural foraging behaviors . Because they have high intelligence and strong problem-solving skills, keeping them engaged prevents boredom and stereotypic behaviors.[1]
Foraging and Puzzle Feeders
Forage Poles and PVC Feeders : Vertical Primate Forage Poles or multi-level PVC pipes with drilled holes require apes to use sticks, fingers, or lips to maneuver seeds, pellets, or honey out slowly.

The best enrichment toys and activities for large primates (such as chimpanzees, gorillas , and orangutans) focus on complex cognitive problem-solving, occupational foraging, and structural manipulation that mimic natural wild behaviors.
Large primates possess high intelligence, tool-using capabilities, and strong social structures, meaning enrichment must challenge their minds and occupy their time effectively.
Top Enrichment Toys and Devices
Busy Boxes and Manipulation Panels Multi-textured wooden or heavy-duty plastic boxes featuring bolts, latches, spinning wheels, and interlocked compartments encourage fine motor skills and persistent investigation.
High-Engagement Enrichment Activities
Scatter and Browse Feeding : Spreading high-value browse, seeds, or grains across deep wood-wool or mulch substrates forces slow, methodical ground foraging instead of immediate consumption.
Termite-Mound Simulation : Drilling holes into heavy logs, filling them with applesauce, honey, or yogurt, and providing sticks or bark tools lets chimpanzees engage in classic, species-typical stick-fishing behavior.
Odor and Sensory Novelty : Introducing uncommon spices (like cinnamon or turmeric), hidden herb bundles, or safe perfumes/extracts to different areas of the enclosure stimulates intense investigation and olfactory exploration.
Question: I'm a zookeeper. What are the best enrichment toys and activities for large primates?
For large primates—especially —the best enrichment is less about buying “toys” and more about creating opportunities for . Current primate-welfare guidance specifically recommends a behavior-driven rather than item-driven approach.
Question: I'm a zookeeper. What are the best enrichment toys and activities for large primates?
Large primates (like gorillas, orangutans , and chimpanzees ) need that challenges their problem-solving skills, accommodates high dexterity, and stands up to immense physical strength.
Browse: Fresh, appropriately identified branches and foliage can provide feeding, manipulation, climbing, and sensory opportunities simultaneously. Smithsonian reports using materials such as bamboo, willow, mulberry, maple, and banana leaves for its great apes.
Climbing and suspension: Ropes, fire hose, platforms, hammocks, overhead routes, and movable climbing elements can promote locomotion and exploration. The exact configuration should reflect the species and individual.
Manipulable objects: Large durable balls, rubber tubs, burlap, cardboard/paper boxes, sheets, and other objects that can be carried, thrown, pulled apart, or incorporated into nest-building. Smithsonian specifically lists boomer balls, rubber tubs, burlap, paper, and boxes among its primate enrichment.
Nest-building materials: Hay, sheets, browse, and other approved materials can encourage construction and resting behaviors, particularly in gorillas and orangutans.
Sensory enrichment: Novel scents and sounds can encourage investigation. Use only substances and concentrations already approved by your institution/veterinary team.
Cognitive tasks: Touchscreens, object-choice tasks, simple problem-solving challenges, and gradually adjustable puzzles can provide substantial cognitive stimulation.
Training as enrichment: Positive-reinforcement training can combine cognition, social interaction, choice, and husbandry. Voluntary participation in behaviors such as presenting body parts, entering a scale, or participating in dental care can also improve medical management.
Creative activities: Non-toxic, water-based painting and other keeper-designed activities have been used with great apes.
What I'd prioritize
Rather than looking for a single “best toy,” I'd build a rotating enrichment program with several functions:
Goal
Examples
Foraging
Scatter feeds, puzzle feeders, hidden food
Tool use
Tubes/containers requiring sticks or manipulation
Locomotion
Ropes, platforms, climbing structures
Manipulation
Balls, tubs, cardboard, burlap
Nesting
Hay, browse, sheets
Cognition
Touchscreens, puzzles, choice tasks
Sensory
Novel scents/sounds
Social
Appropriate group activities and keeper interaction
Husbandry
Voluntary cooperative-care training
The key is choice and individualization. Smithsonian explicitly notes that its great apes can participate in an enrichment activity or walk away, and that keepers maintain calendars so activities remain novel.
Important keeper-level considerations
For a professional collection, I'd have every new item go through your institution's normal behavioral, veterinary, nutrition, and safety review. Pay particular attention to breakage, ingestion, entanglement, pinch/crush points, sharp edges, openings that could trap digits or heads, and whether dominant individuals can monopolize the resource. Enrichment should also complement—not inadvertently replace—the animals' normal nutritional requirements.
If you're at an AZA-accredited facility, the AZA Animal Care Manuals are particularly useful species-specific references; current published manuals include separate Chimpanzee (2010), Gorilla (2017), Orangutan (2017), and Bonobo (2025) manuals.
If you tell me which species (gorilla, chimp, bonobo, orangutan, etc.), approximate ages/sexes, and whether they're indoor, outdoor, or mixed, I can give you a much more specific enrichment rotation with perhaps 20–30 activities divided into cognitive, foraging, physical, sensory, and social categories.
PVC Pipe Feeders:
Kong Stuffers & Heavy-Duty Kongs: Extra-large black (extreme) Kongs frozen with diluted fruit juice, yogurt, applesauce, or mashed browse. They take hours to thaw and lick out, providing fantastic occupational pacing.
Acrylic/Lexan Puzzle Feeders: Wall-mounted puzzle boxes with sliding panels, mazes, or rotating wheels where they must push a food item through a track to retrieve it. It lets you watch their problem-solving and fine motor skills in action.
Burlap Sacks & Cardboard Boxes: Never underestimate a taped-up cardboard box stuffed with wood wool, shredded paper, and scattered seeds or popcorn. They love the sensory aspect of ripping, tearing, and searching through layers.
Structural & Environmental Enrichment
Artificial "Termite Mounds": Concrete or PVC structures with small holes pumped or packed with honey, ketchup, or yogurt. Provide bundles of flexible sticks or willow branches so they can "fish" for the contents just like chimps do in the wild with actual termite mounds.
Dynamic Browse & Bungee Lines: Regularly rotating fresh, safe browse (like mulberry, willow, or bamboo) keeps interest high. Using heavy-duty dynamic rigging or bungee lines allows great apes to test their strength and change how they navigate aerial pathways.
Hammock and Nest-Building Material: Supplying burlap feed sacks, palm fronds, straw, wood shavings, or canvas fabric gives apes the materials to exhibit their species-typical night nest-building behaviors. Orangutans and chimpanzees especially spend a lot of time weaving and crafting elaborate daytime or nighttime nests.
Sensory & Novelty Activities
Ice Blocks with Embedded Produce: Large blocks of ice frozen with whole fruits, berries, and edible flowers. Great for hot summer days, requiring them to wait for the ice to melt or actively smash/crack the blocks apart.
Scents and Spices: Introducing novel olfactory stimuli by lightly misting non-toxic extracts (like peppermint, lavender, or diluted vanilla) or rubbing strong culinary herbs (like cinnamon or oregano) onto logs or structural posts.
Mirror Panels: Securely mounted, distortion-free stainless steel or acrylic mirrors can elicit fascinating social or exploratory responses (though monitor closely depending on individual troop dynamics and dominant males).
If you want to narrow this down, let me know:
Which specific species (chimp, gorilla, or orangutan) you are building for?
Are you looking for inexpensive DIY ideas or heavy-duty commercial hardware recommendations?
For large primates (like chimpanzees, gorillas, orangutans , and bonobos ), the gold standard of enrichment is cognitive challenge, manipulation, and species-specific foraging that stretches out their feeding time from a few minutes to hours.
Top Foraging & Puzzle Feeders
Primate Busy Boxes / Heavy-Duty PVC Feeders: Multi-sided PVC or acrylic puzzle boxes where they have to use tools (sticks, fingers, or wire) to push, flip, or guide treats (like seeds, pellets, or raisins) through internal mazes.
The "Termite Mound" / Honey Logs: For chimpanzees, drilling holes into large, heavy logs and filling them with diluted honey, molasses, or yogurt. They must fashion or use tool sticks to "fish" it out.
Kongs & Heavy-Duty Rubber Toys: Large-size black (extreme) Kongs stuffed with soaked chow, mashed yam, or fruit puree and frozen solid. They require massive persistence to extract.
Otto Environmental Feeders: Commercial devices like the Otto Super Spreader or puzzle balls that release scattered browse or treats as they are rolled or manipulated.
Sensory & Environmental Activities
Browse & Scatter Feeding: Tossing high-value, small-item scatter feed (sunflower seeds, oats, mealworms, chopped greens) deep into a thick, clean woodchip or deep-straw substrate. It forces hands-and-knees tactile foraging that can occupy them for a long portion of the morning.
Ice Blocks & Frozen Juices: Large blocks of ice embedded with whole fruits, berries, and diluted fruit juice. Great for hot days, providing both cooling sensory input and long-term melting/chipping challenges.
Acoustic & Visual Devices: Heavy-duty, distortion-free acrylic security mirrors mounted securely to shift doors or off-exhibit walls, or protected audio setups playing novel sounds or music.
Scent Enrichment: Painting high-extract herbs (like lavender, mint, or small dabs of safe extracts/spices) or infrequent scents (like different perfumes or safe spices) on structural bamboo or rockwork to prompt intense sniffing and investigative grooming/inspecting.
Physical & Structural Manipulation
Burlap Sacks & Cardboard: Giving them unprinted cardboard boxes filled with shredded paper or whole produce, or heavy burlap coffee sacks. Orangutans and chimps love nesting, wearing them as capes, or ripping them down to fine pieces.
Firehose Nets & Hammocks: Interlaced cargo nets made of heavy-duty firehose provide shifting, unstable tactile climbing and hanging platforms that test balance and grip strength.
What specific primate species are you working with, and are you looking for ideas for on-exhibit daytime use or off-exhibit holding/night housing?
Scatter/hide feeding: Distribute portions of the normal diet throughout the habitat rather than presenting everything in one location. This promotes searching, processing, and exploration.
Destructible materials: Large cardboard/paper items, browse, suitable wood, and other species-appropriate materials that can be ripped, manipulated, stripped, or incorporated into nest-building.
Manipulanda: Heavy-duty balls, barrels, ropes, hammocks, boomer balls, and similar objects—but choose equipment specifically engineered for great-ape strength and inspect it frequently for damage. Great-ape size and strength are explicitly identified as design considerations.
Tool-use challenges: Hide food behind barriers or inside devices requiring sticks or other safe implements, where this matches the species' natural behavioral repertoire. Tool use and problem-solving are particularly relevant forms of great-ape enrichment.
Habitat rearrangement: Change climbing routes, feeding locations, substrates, visual barriers, browse placement, and access to different areas. Structural/habitat enrichment can provide exercise, exploration, and choice without introducing a conventional “toy.”
Training as enrichment: Positive-reinforcement sessions for voluntary participation in weighing, visual examinations, presenting body parts, shifting, stationing, and other husbandry behaviors provide cognitive stimulation while building useful husbandry skills.
Sensory enrichment: Novel but appropriate scents, textures, sounds, and visual stimuli can encourage investigation. Rotate them rather than continuously presenting the same stimulus.
Nest-building opportunities: Provide abundant, safe nesting/bedding materials where appropriate, particularly for species and individuals that naturally engage heavily in nest construction.
Social enrichment: For social species, appropriate social opportunities are fundamental and can't really be substituted by objects. Enrichment should also account for competition between group members—for example, providing enough food devices or distributing resources to reduce conflict.
A useful way to choose enrichment
Rather than asking “What toy should I buy?”, ask “What behavior do I want to increase?”
Target behavior
Possible enrichment
Foraging
Scatter feeding, puzzle feeders, hidden food
Manipulation
Durable containers, ropes, large balls, manipulable devices
Tool use
Probing/extraction challenges
Climbing
Variable ropes, nets, platforms, routes
Nest building
Browse, bedding, paper/cardboard
Problem solving
Multi-step feeders and puzzles
Exploration
Habitat rearrangement and novel locations
Training/cooperation
Positive-reinforcement husbandry sessions
Social behavior
Appropriate group opportunities and resource distribution
Food-based enrichment should generally be incorporated into the animal's overall dietary plan rather than functioning as unaccounted-for extra calories; AZA's nutrition guidance specifically emphasizes protecting nutritional integrity when food is used as enrichment.
For a zoo setting, I'd start with the species' current AZA Animal Care Manual and your institution's enrichment/welfare protocol. AZA currently lists manuals for chimpanzees, gorillas, orangutans, and a 2025 bonobo manual.
If you tell me which primate(s) you work with—e.g., gorillas vs. chimpanzees vs. orangutans—and whether you're looking for inexpensive DIY ideas, commercial devices, or a rotating weekly enrichment schedule, I can make a much more specific list.
Puzzle feeders have been shown to increase activity in gorillas, chimpanzees, and orangutans, although individuals differ substantially in how much they use them.
Browse and naturalistic foraging
Fresh, verified-safe browse is exceptionally useful: hang it at different heights, bundle it, scatter it, or incorporate it into the habitat.
Hide portions of the normal diet in leaf litter, hay, cardboard, logs, or other appropriate substrates.
EAZA's gorilla guidance specifically emphasizes browse as a low-calorie way to extend feeding time and promote choice and species-typical feeding behavior.
Manipulable objects
Large durable balls, barrels, crates, fire-hose devices, cardboard boxes/tubes, heavy-duty rubber feeders, hammocks, and similar objects.
For gorillas, the Gorilla SSP specifically lists bamboo shakers, boomer balls, feeder tubes, pump feeders, fire-hose bags, crates, smear boards, stuffed PVC, and PVC-cap feeders as examples.
Tool-use challenges
Create opportunities to extract food using sticks or other approved tools.
Artificial “termite mound”/extractive-foraging setups can be particularly interesting for chimpanzees and orangutans.
For great apes, devices need to be substantially stronger than equivalent equipment for smaller primates.
Change routes and feeding locations rather than simply adding more permanent structures.
Habitat complexity can provide both physical exercise and opportunities for animals to choose how they use their environment.
Training as enrichment
Positive-reinforcement training, targeting, stationing, voluntary weighing, presenting body parts for inspection, and cooperative-care behaviors.
This provides cognitive stimulation while also making veterinary and husbandry procedures less intrusive.
Novel sensory enrichment
Carefully selected scents, new substrates, sounds, bubbles, and novel objects can encourage investigation.
Novelty itself isn't necessarily beneficial, though—monitor the animals' responses and retain items that produce constructive engagement. Smithsonian keepers, for example, report using bubbles and novel objects alongside puzzles and training with orangutans.
Activities I'd rotate
A useful rotation might include foraging → manipulation → climbing/movement → training → sensory exploration, with several opportunities available rather than one “main toy.” For social species, distribute food puzzles and acquisition points so subordinate animals aren't excluded; EAZA specifically recommends multiple, separated acquisition sites for this reason.
The important part is measuring the response, not assuming an expensive or complicated device is better. Track things such as engagement duration, behavioral diversity, locomotion, social interactions, successful food retrieval, and any undesirable/aggressive or repetitive behavior. The 2025 APV/ASP position statement likewise emphasizes functional appropriateness, species-typical behavior, environmental complexity, and evaluation of enrichment programs.
Safety considerations
For large apes in particular, I'd have every new device undergo a keeper safety review for breakage, ingestion/choking hazards, entanglement, pinch points, sharp edges, toxic materials, attachment failure, and potential competition between animals. Browse should be positively identified as nontoxic and free of pesticide/chemical contamination.
If you tell me which species (gorilla, chimpanzee, bonobo, or orangutan), approximate group size, and indoor/outdoor setup, I can give you a species-specific enrichment rotation with concrete toy/activity ideas and difficulty levels.
Puzzle Feeders and Maze Panels : Modular Slide Feeders and Activity Panels mounted to mesh or walls challenge them to push treats through tracking mazes before a reward drops.[1]
Kongs and Heavy-Duty Rubber : Jumbo-sized heavy rubber toys frozen with diluted juice, yogurt, or mashed produce keep them occupied for long stretches.
Sensory and Cognitive Activities
Spices and Perfumes : Sprinkling strong, safe spices (like cinnamon or turmeric) or spraying diluted perfumes/extracts on logs or burlap sacks triggers intense olfactory investigation and natural tracking behaviors.
Nesting Material Distribution : Tossing in large piles of wood wool, alfalfa hay, burlap coffee sacks, or shredded paper gives them a chance to build complex night nests or daytime day-beds, which is vital for psychological well-being.
Prosthetic Termite Mounds : Building a simulated "termite mound" (a barrel or PVC box with small holes filled with applesauce or yogurt) lets chimpanzees use stick tools to "fish" for food just as they would in the wild.
Are you targeting a specific species (like chimps, gorillas, or orangutans), or looking for ideas for a particular setup (indoor holding vs. large outdoor habitat)?
A strong program usually rotates enrichment frequently, tracks individual preferences, and evaluates behavioral outcomes rather than assuming an item is successful because it is used once.
Ice Blocks with Embedded Items : Freezing large blocks of water containing chunks of fruit, vegetables, and juices provides a long-lasting, cooling manipulation task that melts slowly over hours.
If you'd like, let me know:
Which specific primate species you are working with (e.g., chimpanzees, gorillas, or orangutans)
Whether you are looking for group social activities or individual/solitary puzzles
I can tailor these recommendations directly to your habitat's setup.

foraging, manipulation, problem-solving, locomotion, tool use, choice, and social behavior
High-value enrichment ideas
Scatter feeding: Spread portions of their normal diet through substrates, browse, platforms, or multiple enclosure areas so animals have to search and travel. This is one of the simplest ways to increase natural foraging.
Puzzle feeders: Use robust devices that require pulling, rotating, manipulating, probing, or tool use to obtain food. Rotate several designs rather than leaving one device permanently available.
Food-filled tubes and containers: Heavy-duty, animal-safe containers with access holes can encourage persistence and manipulation. For great apes, construction needs to account for their considerable strength.
Tool-use challenges: Put food into cavities or behind barriers where sticks or other approved tools can be used to retrieve it. This can reproduce aspects of natural food processing.
Browse manipulation: Hang, bundle, weave, or distribute safe browse so animals need to bend, strip, pull, climb, or manipulate vegetation to consume it.
Whole-food processing: When consistent with the veterinary/nutrition plan, provide foods in forms that require processing rather than simply presenting bite-sized pieces. Wild apes spend considerable effort processing food.
Foraging substrate: Scatter appropriate foods through hay, wood chips, leaf litter, or another approved substrate. This can turn an otherwise simple meal into a prolonged search activity.
Climbing and locomotor structures: Ropes, platforms, swings, climbing structures, elevated shelves, and movable structures can encourage locomotion and allow use of three-dimensional enclosure space.
Manipulable objects: Durable balls, barrels, puzzle objects, grooming boards, and other objects that can be pushed, carried, opened, stacked, or investigated can provide physical and cognitive stimulation.
Nest-building materials: Particularly valuable for species that naturally construct sleeping nests. Providing suitable materials can encourage species-typical construction behavior.
Training as enrichment: Positive-reinforcement sessions can provide cognitive challenge, choice, communication, and valuable cooperative-care behaviors—not merely “obedience” training.
Novel sensory experiences: Novel visual objects, sounds, textures, or appropriately selected scents can add variety, although sensory enrichment should be evaluated individually rather than assumed to be beneficial.
Social enrichment: For socially housed species, opportunities for appropriate social interaction may be among the most important forms of enrichment. Management should account for hierarchy and individual preferences.
Particularly good for great apes
A useful approach is to build a “work for the diet” program rather than adding lots of extra treats. The 2025 APV/ASP position statement emphasizes foraging, physical manipulation, cognitive challenges, and species-typical behavior; the AZA Bonobo Care Manual similarly recommends scatter feeding and puzzle/feeding devices for apes.
For example, one day's rotation might look like:
Morning: scattered browse and normal diet across multiple enclosure zones.
Midday: several feeding puzzles, spaced apart to reduce competition.
Afternoon: tool-use challenge or food-processing activity.
Later: climbing/manipulation enrichment.
Training: short cooperative-care session with positive reinforcement.
Evening: nesting materials or another low-competition activity.
The important part is variation and evaluation rather than maximizing the number of objects. AZA's enrichment program explicitly encourages moving toward behavior-driven and experiential enrichment.
Safety matters more with large apes
For great apes, ordinary commercial “primate toys” can be inadequate. Enrichment should be inspected for breakage, sharp edges, entrapment, strangulation, choking, and ingestible pieces, and objects need to be appropriately sized and constructed for the individual species and animal.
Also, food enrichment should generally come out of the planned daily diet rather than being extra calories. AZA nutrition guidance specifically says enrichment foods count toward the total diet. Multiple feeding stations can also be important in groups to prevent dominant individuals from monopolizing enrichment.
If you tell me which species you work with (gorilla, chimpanzee, orangutan, bonobo, baboon, etc.) and whether they're indoors, outdoors, or both, I can give you a much more specific enrichment rotation—including DIY ideas, puzzle-feeder designs, browse-based activities, and a weekly schedule.
Slide Feeders & Puzzle Boards : Wall-mounted or mesh-attached puzzle units (like the [Otto Environmental Slide Feeder ](https://www.ottoenvironmental.com/product/pes-slide-feeder/) ) require apes to manipulate tokens, disks, or food items through a maze to get them out.[1]
PVC Feeder Tubes : Heavy-duty PVC pipes capped at ends with drilled holes. Stuffing them with browse, seeds, or smeared-on extracts (like diluted fruit juice or yogurt) forces them to use tools like sticks to extract the contents.
Forage Mats & Scatter Feeds : Tossing small, high-effort items (sunflower seeds, coconut flakes, or popped corn) into deep wood wool, mulch, or grass keeps them occupied searching for hours.
Manipulable & Physical Toys
Heavy-Duty Fire Hose & Cargo Nets : Great for structural manipulation, weaving, and climbing configuration changes. Apes love pulling, fraying, and braiding heavy-duty materials.
Stainless Steel Mirrors & Rattles : Polished stainless-steel plates bolted securely or hanging ring/triangle rattles provide robust tactile and visual feedback that withstands aggressive use.
Paper & Cardboard Shredding : Bundling popcorn, pellets, or treats tightly inside layers of twisted newspaper or cardboard boxes satisfies their natural urge to rip, shred, and deconstruct.
Sensory & Environmental Activities
Ice Blocks & Frozen Scent-Kongs : Freezing juices, mealworms, chunks of fruit, or extracts into massive ice blocks slows down consumption and provides a cooling, high-manipulation challenge on warm days.
Browse Scatters : Swapping out structural branches with leaves, bamboo, or willow gives them a sensory-rich environment to strip bark, build day-nests, and process complex vegetation.
Keeper Insights
“I love forage boards and they were the recommended enrichment for or primates with behavioral issues. We would make a forage mix of coconut, Cheerios, and other small snacks that hid in the grass well. Keeps them busy for hours.”
“Well, from my experience there really isnt anything super-duper primate proof. Or really even a little primate proof. They always find a way to destroy things.”
