Safety Summary

✔ Safe: Plain peanut butter in tiny amounts
⚠ Use caution: Check for xylitol — instantly fatal to cats
✖ Toxic: Xylitol-containing peanut butter

Why

Plain peanut butter without xylitol is not toxic to cats, but cats are obligate carnivores with no nutritional need for it. Most cats aren't even that interested in peanut butter compared to dogs. The main danger is xylitol — an artificial sweetener found in some "natural" or reduced-sugar peanut butters that is highly toxic to pets. Always check the label. High fat content also makes it a poor treat choice.

Portion Guidance

A very small amount very occasionally if your cat is interested. But there's really no nutritional reason to give it.

Risks & Symptoms

Xylitol: liver failure and death — always check ingredients
High fat: pancreatitis, obesity
Aflatoxins: concern with some peanut products

FAQ

Do cats even like peanut butter?

Most don't — they lack sweet taste receptors and peanut butter doesn't have much appeal for them unlike dogs.

Which peanut butter brands contain xylitol?

Brands including Go Nuts, Nuts 'N More, and P28 have used xylitol. Always check current ingredient labels.
