Thread: Front line doesn't always work!

The one thing that I had trouble trying to get the Frontline rep to understand was that my cats don't get challenged either even though they go out into the garden,they can't get out other cats can't get in,because they are round the back even if a cat is in the front unless the flea hops over the bungalow they can't get in,just had an idea,perhaps I can hold a flea high jumping contest & train them up for the olympics ! Seriously though the most likely thing is I brought one home on me from work & things escalated from there,but it shouldn't have done.
