I have a taken in a small semi-feral kitten who is covered in fleas and has a bad eye infection. I took her to the vet yesterday and he covered her in a flea spray (I think frontline); however, I have just picked her up to treat her eye and a flea walked down my arm. He said yesterday that I cannot use advocate for another week as he thinks she is about 8 weeks old (although he also said it would probably be fine). Does anyone have any suggestions on how to get rid of them over the next week?
