8 Vegetables Cats Can Eat (And 11 to Avoid)

Cats are obligate carnivores (meaning cats eat meat to survive), and a cat’s diet should generally be high in protein and fat. But that doesn’t mean your cat can’t enjoy the occasional fresh vegetable treat! In fact, adding a few safe vegetables in small quantities to your cat’s regular diet can provide a few health benefits.

We talked to two expert vets to learn all about the best vegetables cats can eat,, the health benefits of these veggies and the best way to feed them to your cat. We’ve also listed 11 veggies your feline friend should never have.

Before incorporating any new foods into your cat’s diet, always consult with your veterinarian to make sure it’s a safe addition to your pet’s diet given their health, diet needs and current medications. Your vet will tell you if your cat can eat vegetables and, if so, the appropriate serving sizes.

FAQs About Cats and Veggies

Q: Do cats need veggies?

A: No, cats do not need veggies. Because they are obligate carnivores, they need meat to survive. Cat food is formulated to meet that need. Vegetables, however, can be incorporated into your feline’s diet. They are a nice treat, and the added health benefits are a bonus.

Q: Is it OK for cats to eat vegetables every day?

A: Yes, if your cat really enjoys veggies, they can eat them in moderation daily. However, be mindful that vegetables should never exceed 10 percent of your cat’s total calorie intake for the day; and some veggies are better served on occasion.

Q: When should cats eat vegetables?

A:Cats can eat veggies whenever you want to offer them, as long as you're mindful of the amount. You can mix them in with your cat’s food or offer them separately as a treat.

No matter when you give your cat vegetables, always cut them into small pieces if serving whole versus pureed or mashed. Larger pieces can pose a choking hazard.

Q: Can cats eat raw vegetables?

A:While some cats can eat raw veggies, remember that many vegetables are more easily digestible when they’re cooked.

Please remember to thoroughly wash the veggies before feeding them to your cat, whether you cook them or serve them raw. You want to ensure you’ve removed any possible pesticides or other chemicals.

Q: Can I add any seasonings or spices to my cat’s veggies?

A:No! Several seasonings and spices are harmful to cats, so it’s best to always keep their veggies plain.

Knowing the best vegetables cats can eat is helpful when you’d like to add the occasional healthy treat to your cat’s diet. If you have a green thumb or want to develop one, you can grow your own veggies. Follow these steps and tips for planting an edible garden of homegrown pet-safe vegetables.
