My cat ate Pistachio — what to do

Step by step

  1. Take pistachio away and remove any plant material from your cat's mouth so they cannot eat more.
  2. Note roughly how much was eaten and when — this helps the vet judge the risk.
  3. Do NOT induce vomiting unless a vet or poison-control specialist tells you to.
  4. Call your vet or the ASPCA Animal Poison Control Center on (888) 426-4435 (a consultation fee may apply) and follow their advice.
  5. Watch for drooling, pawing at the mouth, vomiting, loss of appetite, or lethargy, and bring a leaf or photo to the appointment.

This is general guidance, not veterinary advice. Pets vary, and a reaction may be to soil, fertiliser, or pesticide as well as the plant. When in doubt, call your vet or the ASPCA Animal Poison Control Center on (888) 426-4435.

My cat ate pistachio — FAQ

Is pistachio poisonous to cats?

Yes — the ASPCA lists Pistachio (Pistacia vera) as mildly toxic to cats. Pistacia vera is not individually listed by the ASPCA toxic-plant database, and the ASPCA notes pistachio nuts are not strictly toxic; treat with caution and verify with a vet. The real hazards are high fat (vomiting, diarrhoea, risk of pancreatitis), shell ingestion (gut obstruction), and aflatoxin from mould on poorly stored nuts, which damages the liver. Keep nuts and shells away from pets.

How serious is it if my cat ate pistachio?

Pistachio is mildly toxic, so most cats get short-lived mouth irritation, drooling, and vomiting rather than a life-threatening reaction. It is still worth a vet call to be safe, especially if your cat ate a lot or symptoms persist.

What symptoms should I watch for?

Signs usually appear soon after chewing: drooling, pawing at the mouth, vomiting, loss of appetite, or unusual lethargy. Pistacia vera is not individually listed by the ASPCA toxic-plant database, and the ASPCA notes pistachio nuts are not strictly toxic; treat with caution and verify with a vet. The real hazards are high fat (vomiting, diarrhoea, risk of pancreatitis), shell ingestion (gut obstruction), and aflatoxin from mould on poorly stored nuts, which damages the liver. Keep nuts and shells away from pets. Any worsening or persistent symptoms warrant an immediate vet visit.

Should I make my cat vomit?

No — do not induce vomiting unless a vet or the ASPCA Animal Poison Control Center specifically tells you to. The wrong action can make things worse. Call (888) 426-4435 and follow professional advice.

How do I stop this happening again?

Keep pistachio well out of reach, or swap it for an ASPCA non-toxic plant — see the best cats-safe plants list.
