If you suspect your cat has consumed lead, the first thing to do is to induce vomiting in the animal. Afterwards, take it to your veterinarian, where they will then prescribe specific antidotes for the lead poisoning.
Follow the advice given by your veterinarian regarding the cat's diet; it is important for the cat's recovery.
Make sure that any possible source of lead is safely packed and kept out of your cat's reach. Also, do not allow your cat to enter a room that has been painted with a lead-based paint.
