Yew is one of the most dangerous shrubs a cat can encounter. All parts of the plant except the red berry flesh contain taxine A and B alkaloids, which block sodium and calcium channels in heart muscle and can cause fatal arrhythmias with very little chewing. Cats often nibble out of curiosity, so even a small encounter is a same-hour emergency.
Watch for drooling, vomiting, and trembling first. Cardiac and respiratory signs follow: a weak or irregular pulse, difficulty breathing, dilated pupils, weakness, and collapse. In severe cases the first sign is sudden death — onset is rapid and progression can be steep.
Signs (and in worst cases, death) can occur within minutes to several hours of ingestion. Some cases have been reported with symptoms appearing several days after exposure, so monitoring should continue beyond the first day.
Call immediately. Any suspected yew ingestion in a cat is a drive-to-the-ER emergency. Phone ASPCA APCC (888-426-4435) or Pet Poison Helpline (855-764-7661) en route — do not wait to see whether symptoms develop.
Remove any plant material from your cat's mouth and surroundings and bring a sample (or a clear photo of the shrub and berries) for identification. Do not induce vomiting at home and do not give activated charcoal without veterinary direction — call ASPCA APCC (888-426-4435) or Pet Poison Helpline (855-764-7661) and follow their instructions while you transport your cat.
