Some peanut butter brands are sweetened with xylitol, an artificial sweetener that is toxic to cats and can cause a dangerous, life-threatening drop in blood sugar, along with vomiting, lethargy, and seizures.
Check the label: ASPCA lists xylitol as a hazard to pets. Sticky, fatty peanut butter gives a cat nothing it needs. VCA advises that treats, snacks and people foods together stay within 10% of a cat's daily calories, with the rest from a complete and balanced cat food. No source we checked gives an amount for this specific food, so ask your veterinarian about your own cat.
Always check the label for xylitol (sometimes listed as 'birch sugar') before offering any peanut butter, and only offer a very small amount occasionally.
Treat it as an emergency and contact a veterinarian or animal poison control hotline immediately — xylitol toxicity can cause a dangerous drop in blood sugar even in small amounts.
Its thick, sticky texture can cling to the mouth and throat, and cats cannot easily clear it. Combined with the xylitol risk in some brands, it is better avoided.
