Hey, I think im having the same issue, my 5 year old indoor persian recently started losing hair along her spine, near the base of her tail. she doesnt seem to itch to terribly. when i looked closer there small scabs on her skin. I quickly purchases some Frontline Plus. I applied it a month ago and then again within the last 2 weeks...i cant say ive seen ANY improvement. Shes lost more hair. Now between her back legs and more on the base of her tail. Is it flot out not working? Is she allergic? HELP!!! pooor kitty
