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.
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.
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.
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).
