What this means for your cat

Cats — toxic. The leaves, stems, and seeds of Black Cherry contain cyanogenic glycosides that release cyanide when chewed; wilting branches and pruned leaves are the most dangerous form. Cats rarely browse on cherry, but any nibble of leaves or a chewed pit warrants quick action because cyanide can act within minutes at high doses.

What to watch for

Brick-red gums, dilated pupils, rapid or labored breathing, drooling, vomiting, and excitement followed by weakness. As poisoning progresses, gums turn bluish, the cat may stagger or collapse, and muscle spasms or seizures can occur.

Time window

Signs can appear within minutes when a large dose is consumed and within roughly 24 hours for smaller exposures. In high-dose poisonings, death can occur within one to two hours. Cats that reach treatment quickly typically recover within 24–48 hours.

When to call the vet

Call immediately. Any suspected ingestion of leaves, twigs, or a chewed pit is a medical emergency, and severe signs (rapid breathing, bright-red or blue gums, collapse) need a vet within the next hour.

First aid at home

Per Pet Poison Helpline, do not attempt home treatment. Speak with a poison control specialist before initiating any therapy and never give hydrogen peroxide without veterinary direction. Get to a vet — the cyanide antidote (sodium nitrite and sodium thiosulfate) and oxygen support are clinic-only.
