Is sago palm toxic to cats?
Sago palm is life-threatening to cats (S4 Emergency): every part of the plant — the seeds most of all — contains cycasin, and any amount can cause liver failure and death, with symptoms sometimes delayed for hours.

This is an emergency. If your cat has chewed or swallowed any part of a sago palm — a seed above all — go to a veterinarian or emergency animal hospital immediately. Do not wait for symptoms: your cat can look fine for hours while liver damage develops, and delayed signs can surface up to 48–72 hours later. Bring a photo or piece of the plant.
