I bought a flea collar for a stray cat we just adopted. :) Also, my Denon X4400 should be delivered tomorrow. What better time to get a new receiver on a Friday before a 3 day weekend!!! You're a good person to do that, and what a beautiful kitty! I don't know if you adopted from a shelter, but if you did it's probably had all the shots and a clean bill of health. We don't let any of ours outdoors, so never needed a flea collar nor any further treatment. No dogs to share fleas with either.
