Can cats eat peanut butter?
It's best not to make it a habit. Some vets say natural peanut butter can be an occasional treat, but it must never contain xylitol, and Cats Protection advises sticking to cat treats instead of human foods.

Why
Sources disagree. VCA describes natural peanut butter as a treat cats love, as long as it is free of preservatives and life-threatening additives such as xylitol. Cats Protection advises sticking to cat treats rather than human foods and warns that nuts can cause problems for cats. We use the stricter level.
Signs to watch for
- Vomiting
- Diarrhoea
- Upset stomach
What to do
A lick of plain peanut butter is unlikely to be serious; watch for vomiting or diarrhoea. If the peanut butter contains xylitol, contact your vet or a pet poison helpline right away, note how much was eaten, and don't wait for signs.
How to give it
If your vet is happy with it: natural peanut butter only, with no xylitol or preservatives, as a rare lick, not a habit.
Questions and answers
Why does xylitol matter?
Xylitol is a sweetener added to some peanut butters. VCA calls it a life-threatening additive, so always check the label.
