Listed by ASPCA as toxic: unripe fruit and seeds can cause stomach upset, and the flesh may form a blockage in the gut.
Short answer
Yes, persimmon is considered toxic to cats and should be kept away from them entirely. The ASPCA lists it as toxic because unripe fruit and seeds can cause gastrointestinal upset, and the flesh may form a dangerous blockage in the intestines. Even a small piece poses a risk, so if your cat has ingested any persimmon, contact your veterinarian or an animal poison control hotline immediately for guidance. Do not wait to see if symptoms develop, as blockages can become serious quickly.
