Is Poison Ivy Toxic to Cats?
Also known as: Eastern Poison Ivy, Toxicodendron radicans · Toxicodendron radicans
What makes it toxic
Urushiol, an oily resin in leaves, stems and roots. It triggers severe contact dermatitis in humans; cats are less reactive, but direct skin contact or ingestion irritates tissue.
Warning signs to watch for
Red, itchy or swollen skin where fur is thin (belly, groin, paws), plus drooling, vomiting or diarrhea if leaves were chewed.
What to do if your cat eats it
Bathe the cat with mild pet shampoo to remove urushiol — wear gloves, since the oil transfers to humans. Rinse the mouth if chewed. Call your vet if a rash spreads, blisters or the cat keeps vomiting.
Common questions
Can my cat give me poison ivy from its fur?
Yes — urushiol clings to fur and transfers to anyone petting the cat. Wear gloves and bathe the cat promptly, and wash any clothes or towels that touched it.
Do cats get the classic itchy rash?
Rarely as strongly as humans. Cats are comparatively resistant, so expect mild local redness rather than the blistering rash people get.
Is burnt poison ivy dangerous to pets?
Yes — airborne urushiol from burning plants can irritate airways and skin of pets and people alike. Never burn cleared poison ivy.
