I have adopted 2 kittens recently and upon taking one (charlie) to the vet, we discovered that he has fleas!
This was discovered within 24 hours of adopting him, and we had used revolution straight the way upon finding out.
I have also used a flea comb to comb out any fleas or flea dirt today, and after continuous brushing, I didn't seem to be able to brush out any more.

A couple of questions:
1. The other kitten I had adopted has previously been flea treated, should I assume that he will be okay?
2. A day after treating Charlie for fleas, he jumped up on my bed. Would the flea treatment be effective by then, or should I be worried for fleas infesting my bed?
3. Would it be necessary to use a flea bomb in my bedroom/house? I have done intensive vacuuming twice since the discovery - just a tad paranoid!
Any input would be very much appreciated!!
Thank you
