Hello, you are through to Dr Linda, a UK based vet with 10 years of clinical experience working out of West London. It will be my pleasure to help you today.

I'm sorry to hear to this and understand your concern; what a frustration.

Oftentimes, the main issue will be the flea burden in the home.

95% of the flea burden live off the cats and in their home.

Have you treated the environment?

If so, which product has been used?

Customer: replied 7 days ago.
Nuvan Staykill and scrupulous vacuuming. I can tell that I've managed to get on top of it because I'm not being bitten on the ankles - but the cats are really struggling.
Expert:  Dr L Simmon replied 7 days ago.
Thank you, ok.It is possible that the fleas are becoming to the active ingredient (Fipronil) in the Frontline.
Expert:  Dr L Simmon replied 7 days ago.
I'd suggest using a product with a different active ingredient.Over the counter, you should try Advantage spot on, which contains Imidacloprid. In my experience it is as effective as Stronghold.We must treat all cats on the same day and keep them dry for 2 days after.
