This is one of the most dangerous things in a house with a cat. The ASPCA lists lilies as toxic to cats, with kidney failure as the clinical sign — and it takes very little: a nibbled leaf, a chewed petal, pollen groomed off the fur, or water from the vase. Go to a vet immediately; do not wait for symptoms.
Call your vet or the ASPCA Animal Poison Control Center at (888) 426-4435 straight away. Tell them what your cat ate, roughly how much, and when, and take the packaging with you. Don't wait for symptoms — with several poisons the harm is done before a pet looks ill.
Never induce vomiting and never give any medicine unless a vet tells you to — it can do more damage than the poison. What we will and won't tell you.
Can dogs eat lilies? — Don't feed it to dogs either.
