Revolution may work well on mites, bumps & no see em's. I bought a new cat tree from a pet store. The cat tree's were up next to the ceiling. I saw a couple parakeet's roosting on a tree & flying around. I took the tree home. 3 days later I had kittens scratching their ears. Little bumps on ears & base of ear. They were looseing hair along the edges of their ears. Everyday another kitten was getting it. The vet did 4 scrapeings. Nothing. She checked them all with a black light, nothing. She did a culture, nothing. She & I were both convinced it was some type of mites, mange mites ?. I put Revolution on them. They were 8 weeks old. I repeated the Revolution in 2 weeks. After 10 days the bumps had disappeared, & no more bumps. The hair fall off where the bumps had been, but grew back, only a lighter color. Just to be on the safe side, I gave those kittens a 3rd dose of Revolution, one month later.
I took the cat tree outside, & sprayed it with premise spray. Let it dry outside, & sprayed it again. In the future all cat furniature will be sprayed prior to bringing into the house. I still wonder if it wasn't some sort of bird mite.
I treated the queen also, even though she had no symptoms. Prior litters had been bug free, no bumps or funky ears. Following this episode her next litter of kittens were getting funky ears at 4 weeks. I used an off label dip on the ears only. A product which used to be labeled for cats/dogs for fleas/ticks/mites. I just used a cotton ball & soaked their ears. That cured it. I don't want to put the name of the dip on here. My vet showed it to me in a older vet manual. I had used the dip on my dogs for years, before the FDA removed the pet label. It still is used on vegtables & fruit trees.
I finally sold the queen as a pet, becuase I did not want to deal with any more funky ears. She had to be carrying whatever mite it was. No other cats caught it from her, only her kittens.
Revolution is expensive. I like it as a general anti-bug prevention. I buy it from Canada Vet at about half price. Ivermectin is similar & takes care of mites in cats & dogs. You can find the doseing on the internet. A breeder friendly vet will tell you the doseing.
