My rat Winkie had Sarcopic Mange. Poor baby was scratching so bad, he lost some of his fur. The idiotic vet I went to didn't do a skin scraping the first time. Just gave him a shot of something and told me that would take care of it. I was worried about him passing it onto my cats as he does have free run of my living room on occasion.

The second trip back I insisted they do a skin scraping and sure enough it was sarcopic mange. They gave me Revolution to put on him. I cleaned his tank with hot water and bleach, and gave him a bath in baby shampoo.
