Hi everyone. Just wanted to pop in for this conversation. I have a similar problem with my Gracie With Tail. She has a loss of fur on the back of her neck and its a pinkish color on the skin. I was recently thinking it was from the Advantage because its right where I put those meds. I haven't used it on Gracie now for about 2 years but she still has that weird spot on the back of her neck. I thought I was imagining things till Nancy and several others said theirs had it also. I hope someone figures this one out. I feel so bad because I feel like I burned her with this stuff. It also looks like she will again be Gracie No Tail this summer after she sheds. She loses all her tail hairs every summer. I am going to have her checked soon for Adreanal. She just turned 4 yrs old. Could she have had it since she was two? I did have one ferret who had it at 15 months and died by the time she was two. She was the sweetest ferret of all the ones I ever had. Loved being held!!! Well, I hope everyone has a Happy Easter.
