Sara - I was horrified when I found fleas on Emily last year! The vet just laughed and said I could have easily brought them in on my shoes or clothing. All it took was one application of Advantage to each cat and the fleas disappeared with the day. He had said if too many eggs had been laid - one more treatment might be needed the next month but very unlikely. The new products (like Frontline, Revolution, Advantage) - drops to place betwen the shoulders - are 100% better than what we had even ten years ago. Amazing, effective, easy and QUICK.

Someone here had a cat with a bad allergic reaction to Revolution - it burned the skin and caused hairloss - so I have heard it is good to place the drops in various places rather than all in one concentrated spot - all between the shoulders but a bit apart from each other.
