Nothing for me to give up. Discovered real fast what damage flea collars do. Use boric acid around the flat, now. We currently have no fleas, even with most of the cats being indoor/outdoor, and a new feral kitten deciding to move in. Can't get near him, but he's been living here for about a month. He absolutely loves the incredible Tachyon (who is a cat), and vice versa.
