I've been doing my 3 cats monthly with frontline but they've still managed to get fleas. I've only found the occasional fleas on the boys and they seem clean now, however I don't seem to be able to get my female clean despite the frontline and regular combing.
I also sprayed the house about 3 weeks ago with indorex (not sure on spelling!).
Anybody got any ideas? Can the vet help? We do live fairly rural and the boys do catch mice etc regularly so could be bringing in fleas.
