Help! Something is wrong with my rat's ear..?
Recently, I got two male rats whom are about 2 months old. One of them, Milo, has something wrong with one of his ears. By the tip, there's this big area that's oddly colored, it looks kind of like there's crust or something. It's kind of a white, grey color and is just covering it. Then, by the edges of the infected area, the ear is red...
He isn't showing any signs of an inner-ear infection, such as walking weird or tilting his head.
I'm really worried about my rattie. Any advice, help, or diagnoses? Thank you so much.
