Why?
Coconut flesh and coconut milk are high in fat, which can cause loose stools, diarrhea or a sore belly. Coconut water is very high in potassium, so it isn't recommended for cats. The shell and husk fibers can't be digested and can cause a blockage.
How much?
A small piece of fresh flesh or a pinch of unsweetened shredded coconut now and then is enough. No sweetened coconut, coconut milk or coconut water.
The risks
- Diarrhea or loose stools (fat)
- Coconut water: too much potassium
- Shell and husk: risk of blockage
- Weight gain, avoid with a history of pancreatitis
Your cat ate some: what now?
A bit of coconut isn't dangerous. Watch for diarrhea, vomiting or belly pain over the next 24 to 48 hours. Call your vet if your cat swallowed pieces of shell or husk, drank a lot of coconut water or if symptoms persist.
Better options
For a treat with healthy fats, a small piece of plain cooked salmon or sardine is a much better fit. Otherwise, a cat treat works fine.
Common questions
Is coconut oil good for cats?
It's often credited with benefits for the coat or hairballs, but the evidence is thin. It's very fatty and can cause diarrhea, so ask your vet before adding any to your cat's food.
Can cats drink coconut milk or coconut water?
No. Coconut milk is very fatty, and coconut water is too high in potassium. Fresh water is all your cat needs.
