i'm going to go out tonight and see if i can find that revolution... if it does kill the mites and their eggs. i know i just have to hurry before this stuff gets worse for jakson. he's got it the worst on his back legs and i've sponged him down with apple cider vinegar because i heard it helps keep the itching down. it's worked alright so far, but i need to get this cured before it becomes an even bigger problem.
