Cats that nibble copperleaf foliage are dealing with diterpene esters — irritating compounds that mostly produce mouth and stomach upset, not life-threatening systemic toxicity. ASPCA classifies it as toxic to cats; treat it as a vet-call event rather than an emergency unless signs are severe.
Drooling, lip-smacking, vomiting, and diarrhea are the most common signs. Some cats also paw at the mouth or skip a meal or two.
Specific onset isn't well documented for copperleaf in cited sources. Diterpene-ester GI irritation typically begins within an hour of chewing, with most uncomplicated cases resolving in 24–48 hours under supportive care.
Call your vet or ASPCA Animal Poison Control (888-426-4435) if drooling or vomiting persists more than a few hours, your cat won't eat, or signs are getting worse rather than better. Repeated vomiting can dehydrate a cat fast.

ASPCA Toxic Plant List

Copperleaf is listed as toxic to both cats and dogs by the ASPCA.
Yes, copperleaf (Acalypha godseffiana) is considered potentially toxic to cats. Compounds in the plant can cause oral irritation, excessive drooling, vomiting, and difficulty swallowing if ingested.
The most common signs are drooling, lip-smacking, vomiting, and diarrhea. Some cats also paw at their mouth or skip meals. Symptoms typically begin within an hour of chewing the plant and most uncomplicated cases resolve within 24–48 hours.
Remove your cat from the plant and rinse their mouth with water if possible. Monitor closely for drooling, vomiting, or pawing at the mouth. Call your vet or the ASPCA Animal Poison Control Center at (888) 426-4435 if vomiting or drooling persists more than a few hours, your cat refuses to eat, or symptoms are worsening — repeated vomiting can dehydrate a cat quickly.
The data does not specify which part of the plant is most concentrated with irritants, so any part of the copperleaf — leaves, stems, or sap — should be treated as a potential hazard. Contact with or ingestion of any portion can trigger oral irritation and gastrointestinal distress.
