What are some good companies that sell pet supplies online?

Absolutely. For the U.S., these are some of the better-known online options:

• chewy.com — Huge selection of food, treats, toys, litter, medications, and supplies. Its Autoship program is particularly useful for recurring purchases.Chewy
• petco.com — Broad selection for dogs, cats, fish, birds, reptiles, and small animals, plus online ordering, pickup, delivery, and Autoship.Petco
• petsmart.com — Another large all-purpose retailer with food, toys, supplies, pharmacy products, and options for shipping, pickup, and same-day delivery.PetSmart
• amazon.com — Convenient for comparing prices and buying common supplies, although I'd pay closer attention to the specific seller and product listing.
• walmart.com — Often useful for everyday pet food, litter, treats, and basic supplies, particularly when price is the priority.

For a typical dog or cat owner, Chewy, Petco, and PetSmart are the three I'd compare first. They have dedicated pet inventories and recurring-delivery options, rather than treating pet supplies as just another category.

If you tell me dog/cat/other pet and what you're buying (food, litter, toys, medication, etc.), I can also compare the best places for that specific category and current prices.

Both in person (I got my first pet, a guinea pig named Mr. Nibbles, at PetCo) and online, shopping at Petco is a breeze. They frequently have coupons and deals, too, like on cat treats for my current pet! I'm partial to their multipacks of Greenies, and so is Motek the cat. — Cannon
