I have a flea problem that I can't decide how to treat.
I have 2 cats: cat 1 goes outside about 20% and stays mostly inside. Cat 2 likes to be outside - he is a big long haired cat.
Both get flea treatment monthly. We used to use Frontline Combo (i.e. strong stuff on prescription). We kept seeign the occasional flea on cat 2 and I was getting bitten about 3 weeks into each months treatment. Cat 1 is always clear of fleas. I decided that maybe treatment is not effective on cat 2 because he sheds his coat regularly in Summer. Switched to Advocate 2 months ago.
Beginning of this week I have been bitten again and cat 2 has fleas again. Cat 1 is clear.
What should I do? Vet says we should spray the house but I think he's picking them up outside so spraying the house will not work. When he is in the house, he sleeps in 1 space which is regularly hoovered. Cat 1 sleeps there too and surely if he was re-infesting himself with eggs/pupae formt hi spot then cat 1 would get them as well.
