Can Cats Eat Peanut Butter? Know If The Snack Is Safe For Your Pet

Oct 31, 2025bySarah McConnell

If you’ve ever opened a jar of peanut butter, you’ve likely had your cat wander over, curious about that irresistible smell. It’s creamy, sticky, and seems harmless – after all, dogs love it. But when it comes to cats, things aren’t quite the same.

This article is for general information only. Always consult your veterinarian before offering your cat new foods or treats.

Cats may be curious about peanut butter, but it offers them little to no nutritional value. Unlike humans or dogs, cats are obligate carnivores, meaning their bodies are designed to get all essential nutrients from meat. Peanut butter is high in fat and sugar – things cats simply don’t need in their diet.

Even a small lick can be hard for them to swallow, literally. Its sticky texture can make it difficult for cats to eat, and it can even pose a choking hazard, especially for older or smaller cats.

What Makes Peanut Butter Potentially Unsafe

While plain peanut butter isn’t toxic in tiny amounts, many store-bought varieties include ingredients that can be dangerous. Xylitol, an artificial sweetener sometimes found in sugar-free peanut butter, is extremely toxic to pets and can cause a rapid drop in blood sugar, seizures, or even liver failure.

Salted or flavoured peanut butters can also upset your cat’s stomach and lead to vomiting or diarrhoea. Because cats have smaller bodies and more sensitive digestive systems than dogs, even a spoonful can cause problems.

Better Treat Options For Cats

If you’re tempted to give your cat a little treat, stick with something made specifically for felines. Cooked chicken, tuna flakes, or vet-approved cat treats are far safer and actually enjoyable for your pet.

You can even find cat-safe pastes and lickable treats that mimic the texture of peanut butter but are formulated to support feline nutrition.
