Verified against ASPCA/provenance audit 2026-05-06 on May 6, 2026.
Signs to watch for
Drooling, vomiting, diarrhea, tremors, difficulty breathing, and potential collapse.
Escalation note
This plant is extremely dangerous. Ingestion can lead to sudden cardiac failure. Contact your veterinarian or an emergency animal poison control center immediately if ingestion is suspected.
First aid at home
Pet Poison Helpline advises: remove your pet from the area, check that it is breathing and acting normally, and do NOT give home antidotes or induce vomiting without instruction from a vet or poison control. Bring a sample of the plant or a clear photo to the clinic.
What to watch for
Earliest signs in cats are drooling, vomiting, and trembling. Watch for dilated pupils, weakness or staggering, and laboured or rapid breathing. Because taxines act on the heart directly, a cat can collapse from arrhythmia before any of the milder GI signs become severe.
Time window
Pet Poison Helpline reports that signs can appear within hours of ingestion and that cardiac collapse and death can occur with little warning. Exact onset for cats is not well documented in the cited sources.
When to call the vet
Call immediately. Any suspected ingestion of yew foliage, bark, or seed is a same-hour emergency — do not wait for symptoms to develop, and do not wait for a callback.
What this means for your cat
Cats: this is one of the most dangerous plants you can have around a cat. The ASPCA lists every part of the yew except the red aril as toxic, and the taxine alkaloids it contains can stop the heart with little warning. Even chewing on a few needles is a veterinary emergency.
