Verified against ASPCA/provenance audit 2026-05-06 on May 6, 2026.
Signs to watch for
Drooling, vomiting, decreased appetite, and oral irritation.
Escalation note
Ingestion of large quantities may lead to more severe systemic effects due to calcium oxalate crystals. Please contact your veterinarian if you suspect your cat has ingested this plant.
First aid at home
Do not induce vomiting at home — Pet Poison Helpline specifically warns against that for cats. Remove any remaining plant material and rinse fragments from the mouth and paws. Then contact your vet or Pet Poison Helpline before doing anything else.
What to watch for
Mild exposures: drooling, vomiting, mild diarrhea, and a brief loss of appetite. Larger ingestions can add weakness, tremors, and lethargy as blood calcium drops. Bloody diarrhea is reported. Renal failure is rare but possible after a large meal of the plant.
Time window
GI signs typically begin within a few hours and ease within 24 hours for small exposures. With a large ingestion, low-calcium and renal effects can appear over the first day.
When to call the vet
Call right away if you saw your cat eat more than a leaf or two, or if you see weakness, tremors, repeated vomiting, or any blood in vomit or stool. For a small nibble with no symptoms, call for guidance — it's usually mild but worth a check, especially in kittens or older cats.
What this means for your cat
Shamrock plant contains soluble oxalates that, in large amounts, can drop a cat's calcium and rarely cause acute kidney injury. The plant tastes very bitter, so most cats stop after a nibble — small chews tend to cause only mild GI upset, while a serious binge is the dangerous scenario.
