In march when I had KittyKitty at the vets she's allergic to fleas and get sores on her the vet said to use Advantage Multi on her so in april I put it on her and in may as well she is due for it again but I have notice the hair on her ears are gone she was fine with frontline plus well she didn't go bald on her ears should I stop with the Advantage Multi? Have 5 more applications left bought the 6month one and it came with a free one BabyCat gets frontline plus she's not allergic to fleas so the vet said she's fine with that. Just seems like I am having no luck with my babies 
I will post a picture of what her ears look like
