Can Cats Eat Peanut Butter?
Yes, cats can eat peanut butter, but it’s not a good idea to give it to them regularly. While it’s not poisonous, it doesn’t provide any real health benefits and could cause problems.

Why Peanut Butter Isn’t Good for Cats
- High in Fat & Calories – Too much can lead to weight gain and obesity.
- Hard to Digest – Cats’ digestive systems aren’t designed for plant-based proteins, so peanut butter may upset their stomach.
- Possible Allergies – Some cats might have allergic reactions like itching, vomiting, or diarrhea.
- Unhealthy Ingredients – Many peanut butter brands contain added sugar, salt, and xylitol (a sweetener that is toxic to cats).
If You Want to Give Peanut Butter…
- Use a tiny amount (pea-sized) and make sure it’s unsalted and xylitol-free.
- Never mix it with medicine unless your vet says it’s safe.
Healthier Treats for Cats
Instead of peanut butter, try:
✔ Cooked chicken or fish (rich in protein)
✔ Cat-friendly treats (made specifically for cats)
✔ Pumpkin purée (helps with digestion)
Final Answer: Can Cats Eat Peanut Butter?
A tiny amount once in a while? Yes.
Regularly? No.
