Q: Is Plums toxic to cats?

Warning: Toxic. Plums (Prunus domestica) are a sweet fruit, and the fleshy part is generally safe for cats in very small amounts. However, the pit, stems, and leaves are highly dangerous because they contain amygdalin. When a cat chews or crushes a plum pit, the amygdalin mixes with enzymes in their digestive system to release hydrogen cyanide (HCN). This is a deadly poison that stops the body's cells from using oxygen. If a cat eats a pit, they may show signs like heavy breathing, weakness, vomiting, and even seizures or a coma. While a tiny piece of ripe plum flesh without the pit won't hurt your cat, it has a lot of sugar and gives them no real nutrition. Never let your cat near the pits or leaves, and contact a veterinarian immediately if you think they have chewed on one.

Important Notes

Pit, stems, and leaves: toxic — amygdalin yields HCN via beta-glucosidase cleavage

Mechanism: HCN inhibits cytochrome c oxidase, halting cellular respiration

Symptoms from pit ingestion: rapid breathing, weakness, drooling, vomiting; severe cases cause seizures and respiratory failure

Ripe flesh: safe in very small amounts, but offers no nutritional benefit and is high in sugar

Always remove the pit completely before offering any fruit; avoid dried plums (prunes) as high fibre causes diarrhea
