You can try bathing them in a moisturizing oatmeal-based shampoo if you feel up to it. I have not heard of this happening with Revolution, so it could be that, or something else entirely. I would decide to stick with Frontline, or if you are wanting something that will protect against fleas and heartworm for cats, there is Advantage Multi. AdvanTIX is strictly a dog product and should not be used on cats!
