Be careful. Plain peanut butter isn't toxic to cats, but some brands add xylitol, a sweetener that is dangerous to pets — always check the label. Even xylitol-free peanut butter is fatty, salty, and sticky, offering a cat nothing it needs. If you use it at all, use a tiny smear.

Why this answer
The headline risk is xylitol, a sugar substitute in some peanut butters that can cause a rapid, dangerous blood-sugar drop and liver injury in pets, so a xylitol-sweetened jar is a real hazard. Even without it, peanut butter is dense fat and salt with no carnivore value, and its thick, sticky texture can be awkward for a cat to swallow.
Watch for
Vomiting or diarrhea from the fat
With xylitol: weakness, wobbliness, or collapse from low blood sugar
Drooling or trouble swallowing the sticky texture
Loss of interest in regular food
How much is okay
At most a lick-sized smear of plain, xylitol-free peanut butter, rarely — never a spoonful, and never as a routine treat.
Serve it safely
Read the ingredient list and never use any peanut butter containing xylitol or 'birch sugar'.
Choose plain, unsalted, unsweetened peanut butter if you offer it at all.
Use only a tiny amount, for example to hide a pill, not a heaping spoon.

Answer card
No food checked yet.
Type what your cat is eyeing — or already stole — and the answer lands right here, without leaving the page.
Remove access. Take the food away and move your cat to another room.
Note the facts. What was it, roughly how much is missing, and when? Keep the packaging.
Call before symptoms. For chocolate, onion, garlic, grapes, raisins, alcohol, or anything sugar-free (xylitol), call a hotline or your veterinarian now — early treatment is easier and cheaper.
Never do this
Do not induce vomiting, feed milk, salt, or oil, or wait overnight to "see how it goes". Signs of chocolate or Allium poisoning can take hours to days to appear.
Go to an emergency vet immediately if
Your cat is collapsing, twitching or seizing, struggling to breathe, drooling heavily, vomiting repeatedly, or wobbly on their feet.
