I'm a new member of rat forum, and joined to ask for some help. I have two males rats, both approximately 16 months old. The larger of the two has an excessively oily coat that causes him to scratch to the point of bleeding. His back and neck are constantly scabbed. At the moment I am bathing him every other day to try to control the oil, but he remains quite oily and itchy. I was wondering if neutering may help the issue, as our vet told us that it is likely due to high testosterone levels. If anyone has any information, or knows of anything else that may help please reply! Thankyou!
