I'm sorry to hear this. I use advantage on my cats every month and I've never had any problems like this. Storm has had a bald spot from it before so now I make sure to squeeze it out in at least four different places on him. This could be related to stress and she may have always had it and it's just now coming out. I would think that something like pred would probably help her. This will also increase her appetite so she'd start eating better.

My Pearl has Eosinophilic Granulona Complex and her's is actually caused by diet. Since she's been eating a grain free diet of Innova Evo she hasn't had a break out. I did try Taste of The Wild which is also grain free but she broke out. She breaks out on her chin and lips. My vet put her on pred for a short time and this cleared her up. Here's a link to this disease: http://www.petplace.com/cats/eosinop...lex/page1.aspx. I hope that she'll recover quickly. I'll keep her in my thoughts and prayers. Please continue to keep us updated.
