I was given a tiny rescue kitten to foster -- she was covered with fleas and ticks. I brought her to the vet who told me my little rescue had one of the worst cases of flea infestation she had ever seen. They gave her a capstar and a dose of revolution. When I got her home, I immediately went to Petbucket and ordered revolution for kittens - got 3 months supply for a lot less than what the vet charged. It arrived way ahead of time before her next scheduled dose, so order processing and shipping was definitely not a problem. Of course, my kitten is no longer a foster, but has her forever home and it's so nice to know she will be free of fleas for the rest of her life! Thanks Petbucket!
