I noticed fleas on our cat about a month ago, treated with over the counter frontline, which did nothing so took cat to the vet about 2 weeks ago. He gave her an injection to stop the eggs being viable (can't remember what it's called). He also gave me some stronghold which I put on her a week ago.
All seemed good for a few days but I've just seen two of the buggers this morning. One was on the cat and the other hopped into my water. I have hoovered and sprayed, but maybe not as much as I could have, definitely not everyday (I've got a very Hoover phobic toddler which makes it a bit tricky).
Shouldn't the treatment have worked by now despite the lack lustre hoovering?? Please tell me what to do next, I really don't want another infestation
