rat wound

Question
hello, i have a male hairless rat that is roughly 8-9 months old. he always gets a few cuts here and there that go away within a few days. but about 2 weeks ago he scratched himself behind his ear. it as a small scrape at first and i thought that it would heal just like any of the others. a few days later i noticed it got bigger so i started to watch him very closely. i noticed that he keeps scratching everytime a scab developes, opening it and making it get bigger. now it is the size of my finger tip. i've been putting neosporin on it after cleaning it, but i'm still concerned about infection,and i don't know what i can do to make it heal.

Answer
Does he have ear mites or something? I am not a rat expert but if he is still scratching it that makes me think he must have some kind of bug that is making it itch.

I don't know Leigh, since I don't do rats. You should call a vet or post in here to the rat section. Maybe a local pet store can help you also. I have never even heard of a hairless rat.

Very odd.
