Pet ingestion lookup
My cat ate Silver Dollar Plant - what should I do?
Crassula arborescens
Potentially toxic
Contact your veterinarian or an animal poison-control resource now, especially if any amount was chewed or swallowed.
Verified against ASPCA/provenance audit 2026-05-06 on May 6, 2026.
Signs to watch for
Vomiting, depression, ataxia (loss of coordination), and bradycardia (slow heart rate).
Escalation note
Ingestion can lead to gastrointestinal distress and neurological signs. Please contact your veterinarian or a pet poison control center immediately if you suspect your cat has consumed any part of this plant.
What to watch for
Most common: vomiting, often within 15–20 minutes, sometimes followed by diarrhea and lethargy 1–4 hours later. Cat-specific: ataxia (drunken, uncoordinated walking). Less common: muscle tremors and a slow heart rate.
Time window
Pet Poison Helpline reports onset within 15–20 minutes (vomiting and drooling first), with diarrhea and lethargy following in 1–4 hours. Most cats recover within 24 hours.
When to call the vet
Call immediately if your cat shows wobbliness, tremors, or repeated vomiting that won't stop. For a single mild vomit, monitor for two hours and call if signs continue or new ones appear (lethargy, refusing food).
What this means for your cat
Crassula arborescens is on the ASPCA toxic list, and cats are the more sensitive of the two pets. Beyond the usual vomiting, ingestion can produce a wobbly, drunk-looking gait or, less often, tremors — that's the cat-specific tell. Most cases are mild, but a wobbly cat warrants a call.
