Is it safe to use Revolution and Frontline together for kitten mites?

I'm sorry to hear about your issue with Cheyletiella. They are a bothersome parasite to deal with! Apply Revolution every 2 weeks for 3 treatments (use appropriate dose for your kittens' weight). You can use Frontline Plus as well if you feel you aren't getting the results you wanted at the dosage of Revolution stated above. Fontline Plus can be applied every 2 weeks at the correct dose based off body weight for this problem. You should also use a lime silver dip or topical flea product to clean the kittens. Diluted bleach 1 part bleach:9 parts water sprayed on all surfaces and allows to sit for 10 minutes before wiping clean should help. All bedding and toys should be washed in hot water or thrown away. Good luck and thank you for contacting me today!
