Why?
Pineapple flesh is very sweet and acidic, and it contains bromelain, an enzyme that can irritate the mouth and stomach. The fibrous core and spiky skin can't be digested and can cause a blockage. Canned pineapple, often packed in syrup, is even more sugary.
How much?
One or two small cubes of fresh pineapple once in a while is enough. Remove the skin, eyes and core, and skip pineapple in syrup.
The risks
- Mouth or stomach irritation
- Diarrhea or vomiting from too much fruit
- Core and skin: risk of blockage
- Extra sugar for diabetic cats
Your cat ate some: what now?
A small piece of pineapple isn't dangerous. Watch for vomiting, diarrhea or drooling over the next 24 to 48 hours. Call your vet if your cat swallowed core or skin, ate a lot, or if symptoms persist.
Better options
For a treat that truly suits your cat, a small piece of plain cooked fish or chicken is ideal. If you want fruit, a couple of blueberries are less acidic and less sugary.
Common questions
Can cats eat canned pineapple?
Better not: it's often packed in very sugary syrup. If you want to share, use fresh pineapple.
Can cats eat pineapple skin or leaves?
No. They're tough, spiky and impossible to digest, and can irritate the mouth or block the gut. Only the soft flesh is OK.
