We have to put this liquid thing that stops worming amd flees and stuff on the back of my cats neck every month or so. She hates it and runs away when she see or smells it. She also wont let us touch her for a little while or she will grr and hiss. We have to part the fur on tge back of her neck so we can put the liquid on her skin. Does anyone know any good methods o applying this stuff?
