Persimmon — Food safety facts
Do not feed · Cats · full breakdown on the linked food page
Listed by ASPCA as toxic: unripe fruit and seeds can cause stomach upset, and the flesh may form a blockage in the gut.
Dogs and cats carry the same rating (Do not feed), so the notes below hold for either pet.
Persimmon should not be given to cats at all. Even a small amount can do harm, so there is no portion small enough to be safe.
Do not induce vomiting and do not give milk or oil to “dilute” it. Note the food and roughly how much was eaten, then call your vet or a pet poison hotline and follow their advice on whether to bring the pet in straight away.
Why these cautions matter
Stone-fruit pits and some seeds release cyanide when crushed, and quite apart from that they are a choking and blockage hazard.
