I'm not sure what kind of cat, but I don't think it matters but it was a story my co-worker had told me. She said that one of her dogs had passed away, so she had some kind of heart-worm or flea medicine from the veterinarian for the dog. She decided to use the medicine on the cat, and the cat died but not before a trip to the vet. The vet told her that was one of the dumbest things you could ever do. The ironic thing is that her cat's name was Lucky.
