We've had our cat for about 7 years and she's 12. I've used various flea treatments but mainly frontline, to start with, then when it stopped working, we switched to program.
However this seems also to have stopped working, and last month I used some frontline we had left over and the program as usual.
I've been combing her and she still has a lot of fleas, which bother her.
maybe they are coming from the carpets etc, from a brief lapse in treating her, but surely they would stop reproducing after we'd resumed - it's been several months now.
I'm not sure what else to try. Any tips most welcome - and I'd rather not treat the house if possible, as it's very cluttered and I don't like the idea of pesticides everywhere.
Thanks
