Verified against ASPCA/provenance audit 2026-05-06 on May 6, 2026.
Signs to watch for
Drooling, vomiting, diarrhea, and potential heart rhythm abnormalities.
Escalation note
Ingestion can lead to serious cardiac distress. Please contact your veterinarian or an animal poison control center immediately if you suspect your cat has consumed any part of this plant.
First aid at home
Do not induce vomiting and do not give any over-the-counter human medications at home — speak with a veterinarian or Pet Poison Helpline before any home care.
What to watch for
Most common: drooling, vomiting, and diarrhea. Less common but more serious: weakness, collapse, and abnormal heart rate or rhythm.
Time window
Gastrointestinal signs usually appear within a few hours; cardiac signs, when they occur, follow larger ingestions and are not consistently timed in the cited sources.
When to call the vet
Call your vet or Pet Poison Helpline (855-764-7661) for any vomiting or diarrhea after suspected ingestion, and immediately if your cat is weak, collapses, or you suspect more than a small bite was eaten.
What this means for your cat
Cats that nibble Mother of Millions usually develop only mouth or stomach upset, but the plant carries cardiac toxins (bufadienolides) that can — with larger ingestions — cause dangerous changes in heart rhythm. Treat any sign of weakness or collapse as an emergency.
