Hey guys and gals, what's the word on using Revolution 2 weeks after an Ivermectin injection? Mika's mites are far from gone, she's getting bald spots behind her ears and her rump and still very itchy. I feel so terrible. First that she's got the mites, second that I didn't do my research before letting her get an Ivermectin shot (thank god she's okay!), and thirdly because she's so miserably itchy =((((.
