My cat ate Azalea - what should I do?
Rhododendron spp
Potentially toxic

Verified against ASPCA/provenance audit 2026-05-06 on May 6, 2026.
Signs to watch for
Vomiting, diarrhea, hypersalivation, weakness, tremors, and potential cardiac arrhythmias.
Escalation note
Ingestion of even a small amount can be life-threatening. Contact your veterinarian or an animal poison control center immediately if ingestion occurs.
First aid at home
If you can do so safely, remove any plant material from the cat's mouth and bag a leaf or flower sample to bring to the vet. Do not induce vomiting at home — call your vet or ASPCA APCC for instructions before giving anything by mouth.
What to watch for
Drooling, vomiting, and diarrhea usually come first, typically within a few hours of chewing. Watch closely for weakness, wobbling or stumbling, slowed or irregular heartbeat, and a drop in body temperature. Severe cases progress to low blood pressure, tremors, depressed consciousness, and cardiac collapse.
Time window
Signs typically begin within a few hours of ingestion. With prompt supportive care most cats recover over 24–48 hours; severe cardiac cases can take longer and are occasionally fatal without veterinary treatment.
When to call the vet
Call your vet or ASPCA Animal Poison Control (888-426-4435) immediately if you saw chewing — even before symptoms appear. If you only find evidence afterwards, call as soon as you see persistent drooling, repeated vomiting, weakness, or any change in heart rate or breathing. Don't wait it out.
What this means for your cat
Cats — azaleas are toxic. Grayanotoxins in every part of the plant disrupt sodium channels in muscle and nerve tissue, and because cats are small, even a few chewed leaves or a single flower can produce real illness. Treat any confirmed chewing as an emergency and call your vet.
