I have 2 feamale cats one of which has 4 kittens 8 weeks old, I can't control the fleas, I used frontline on the 2 adults when kittens were 3 weeks old as advised by vet, I then used revolution on kittens at 6 weeks old and frontline again on the adults, they still have major flea problems, as I couldn't aford to do this again I got spot on for all at the supermarket 2 days ago and it seems worse, all the time I am vacuuming and washing floors, I'm very frustrated and want to find homes for the kittens but don't feel right giving them away with fleas... what to do next?
