What this means for your cat

Yew is one of the most dangerous plants a cat can chew. Taxine alkaloids in the needles, bark, and seeds disrupt the heart's electrical signals and can cause sudden cardiac death — sometimes without much warning. Treat any nibble as a true emergency, even if your cat looks fine.

What to watch for

Early signs include muscle tremors, drooling, vomiting, and labored or fast breathing. Cats can progress quickly to weakness, dilated pupils, an irregular heart rate, collapse, or sudden death — in some reports with very little warning before cardiac collapse.

Time window

Signs can appear within 30 minutes to a few hours. Cases of collapse within 15 minutes of ingestion have been recorded in monogastric animals. There is no safe observation window.

When to call the vet

Go to an emergency veterinary clinic immediately. Call ASPCA Animal Poison Control at (888) 426-4435 or Pet Poison Helpline at (855) 764-7661 on the way. Do not wait to see whether your cat develops symptoms.
