7. Grooming Supplies

Grooming your pets takes a lot of work. Why not make it easier with one of the best Costco pet products available? The FurMe Professional grooming kit is a 5-in-1 kit featuring a vacuum. With its 2-liter container, you can combat shedding season and ensure your pet is clean and comfortable. It’s perfect for all parts of grooming, from brushing to clipping, with an ultra-quiet noise level to keep your pet calm.
6. Dog Beds

Dog beds are pretty easy to purchase. Most vets won’t have an issue with which bed you choose, as long as the size is large enough for your pup to sprawl out, it’s durable to withstand pawing and chewing, and it has enough cushioning and support for your dog’s joints. Washability is another perk that owners should look for to make cleaning stress-free. Thankfully, some of the best Costco pet products focus on all of these points, like this Kirkland Signature Bolster bed that’s washable, has durable fabric, and is cushioned for maximum comfort. There’s also the 2-in-1 bed with a removable foam cushion that can be used with the bed or separately, and even a removable cover for cleaning ease.

5. Pet Technology

Pet technology, especially smart litter boxes, is becoming more and more popular these days. And while there is always some risk to having smart technology, several vets recommend this as a total game-changer for your household. The Litter Robot is actually approved by Dr. Anna Foster, a cat mom and emergency veterinarian. Costco carries both the Litter Robot 3 and 4 bundles. This ensures your cat has a clean space every time without you dealing with scooping messes. Plus, you can connect it to your phone to keep track of when to clean out the smart litter box.
4. Treats

Some of the best Costco pet products are in the treat aisles. Your pup or cat will be excited to see you walk through the door with these delicious items in hand. Fortunately, there are several pet-approved products, such as the popular dental chews from Greenies. Or grab a package of Canature NutriBites beef liver or dried salmon, great treats for both your cat or dog.

3. Supplements

Give your furry friend a longer, healthier life by adding supplements to their diet. While you’ll want to check with your vet to see recommendations before adding these, supplements are the perfect way to prevent any future injuries, focus on their overall health, and address any concerns, such as joint pain. Costco carries a wide range of products, from their store brand Kirkland Signature, to the highly approved supplement brand Zesty Paw, which has probiotic bites, aller-immune bites, calming bites, and more.
2. Prescriptions

Just as you can grab your prescription at an affordable price at Costco, you can also pick up your pet’s prescription. Not only are many prescriptions available at a discounted rate, but it also makes your life easier to grab them while grocery shopping. After you have your prescription from the vet, they can send it right over to your local Costco, and will often encourage it if it means a cheaper price for you.
1. Kirkland Signature Food

There’s a good reason why Kirkland Signature’s pet food is the best Costco pet product on the list. They’re beloved by many pet owners and are recognized as high-quality while being cost-effective with vets. Kirkland’s dog food is made with real meat like chicken, lamb, or salmon, and offers a balanced meal that is nutritious and affordable. This also goes for cat food, which is loved for having probiotics and prebiotics for a healthier gut and overall health.

It is costly to buy the large quantity at Costco only to find your cats do not like it. I’ve had that issue with the wet foods so have been wary to try the dry. How about small sample bags to try?
When you switch foods, you do it gradually mixing old with new.
My cats like Kirkland just fine.
