4 min read

Learn whether plum pits pose a toxicity risk to cats, what signs may appear after exposure, and what immediate steps to take if your cat may have been exposed.

Quick Answer

Yes, plum pits are toxic to cats. The pits require chewing to release cyanide. Whole pits swallowed are more likely to cause obstruction, but both risks should be taken seriously. If your cat may have been exposed, contact a veterinarian or animal poison-control service right away, even if no signs are visible yet.

Before using any tool, contact a veterinary professional if your cat may have been exposed.

Safety Verdict

Toxic. Fruit pits and seeds contain amygdalin, which releases cyanide when metabolized. Cyanide inhibits cellular respiration, preventing cells from using oxygen. The pits also pose a choking and obstruction risk.

The pits require chewing to release cyanide. Whole pits swallowed are more likely to cause obstruction, but both risks should be taken seriously.

What It Is

Plum pits contain amygdalin, which releases cyanide when chewed and metabolized. The pits also pose an intestinal obstruction risk.

Why It May Be Harmful

The toxic principle in plum pits is amygdalin and related cyanogenic glycosides. Fruit pits and seeds contain amygdalin, which releases cyanide when metabolized. Cyanide inhibits cellular respiration, preventing cells from using oxygen. The pits also pose a choking and obstruction risk.

Signs of toxicity may include:

  • Dilated pupils
  • Difficulty breathing
  • Bright red gums
  • Vomiting
  • Salivation
  • Shock
  • Collapse
  • Seizures

Timeline: Signs can appear rapidly, within minutes to hours.

Can be life-threatening. Cyanide poisoning can cause rapid death.

What to Do If Your Cat Eats It

  1. Contact a veterinarian or animal poison-control service immediately.
  2. Remove any remaining substance from your cat's reach.
  3. Do not induce vomiting unless instructed by a veterinarian.
  4. Do not give food, milk, charcoal, or home remedies.
  5. Bring the substance, plant, or packaging for identification.
