Can Cats Eat Peanuts?
Yes — plain, unsalted peanuts are not considered toxic to cats, but they should only be an occasional tiny treat. Peanuts are high in fat, can upset the stomach, and peanut butter products may contain ingredients that are unsafe for pets.
Plain peanuts are not toxic, but they are not an ideal food for cats
Cats are obligate carnivores, so peanuts do not offer the balanced nutrition they need. If your cat steals a small amount of plain, unsalted peanut or xylitol-free peanut butter, it will usually just need monitoring, but fatty or seasoned products can cause stomach upset and larger amounts may trigger vomiting or diarrhea.
How urgent is this?
Go to the ER now
- ● Your cat is choking, gagging, struggling to breathe, or may have inhaled a peanut piece
- ● Your cat ate peanuts or peanut butter with chocolate, raisins, onion, garlic, or another known toxic ingredient
- ● Your cat has severe signs after eating peanuts, such as collapse, repeated vomiting, severe lethargy, or trouble breathing
See a vet within 24 hours
- ● Your cat ate a large amount of peanuts or rich peanut butter and now has vomiting, diarrhea, abdominal pain, or refuses food
- ● Your cat ate heavily salted, spicy, flavored, or sugar-free peanut products
- ● Your cat has a history of pancreatitis, diabetes, obesity, food allergies, or a sensitive stomach and ate peanuts
Watch at home, call if it worsens
- ● Your cat ate a tiny amount of plain, unsalted peanut or a lick of xylitol-free peanut butter and is acting normal
- ● Mild temporary stomach upset, such as one soft stool, but otherwise normal behavior
- ● You removed the shell and there are no signs of choking or digestive distress
How to Safely Feed Peanuts to Your Cat
If you choose to offer peanuts, keep them as a rare treat only. Plain, unsalted, shelled peanuts are the safest form, but many cats do not need or benefit from them nutritionally.
- Offer only plain, unsalted, unseasoned peanuts with the shell removed
- Give only a very small amount, such as part of a peanut or a tiny lick of xylitol-free peanut butter
- Avoid salted, honey-roasted, spicy, chocolate-coated, or flavored peanut products
- Check peanut butter labels carefully and avoid products with xylitol or added sweeteners
- Keep treats under 10 to 15% of your cat’s daily calories, and call your vet if your cat vomits or seems painful after eating a fatty treat
