Take your cat to the vet, ask them to check and see what they say. Then board the cat at the vet location for 5-6 hours. Give the cat a capstar pill, that should kill the fleas on the cat. Make sure the cat is still on revolution before of course.

Then go home, get everything you can in the washing machine, and wash and dry on hot.

Then vacuum everywhere. Then spray vibrac knockout, then get out of your home for 4 hours until it all dries. Go back vacuum one more time, and then pick up your cats. I would recommend vacuuming twice a week and washing once a week.

I would keep your cat on revolution for another 3 months, and you can do this entire process with boarding the cat and spraying vibrac 2 weeks after you did this.

You should be good from there.
