I applied frontline plus on my cats on May 22. I made the mistake of letting one of them go outside right after applying it (he always wants out after I apply it, he hates the smell and he is allowed outdoors for awhile each day) we live in a small home and it gives him an outlet. Anyway unfortunately out of nowhere a rain shower comes, and as soon as I realized it probaly 5 minutes after it started I got him back in. He got wet needless to say... so I am worried that it just got washed off and ruined the entire application. I contacted frontline and was told that it won't wash off but I see there's a flea around his head area tonight. I wonder if it would be okay to reapply it? Anyone ever experienced their pet getting wet soon after applying and it didn't work? or does it work and the flea I am seeing it is going to die off just hasn't yet?
