The same applies to cats: species cannot be identified visually, and some cause liver failure with a deceptive well-looking period in between. Call rather than watch.
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.
