my hamster lost a little fur and was bleeding, will anything happen?

i often notice that my hamster will keep biting his cage too and has a little fur stuck on his food bowl and cage bars. will anything happen? hes around 1 and 1/2 yrs old to 2 yrs
Answers:
was the bleeding from his mouth area? if it's just a little he'll be ok but u want to stop it from getting worse. he is biting to tell u he wants out. he is bored. his cage is probably too small and sometimes just getting a bigger one or adding one on will work. but most of the time u need to get him a hamster ball. let him run a couple hours a day. put tape on thelid so u dont have to watch closely and just let him run an hr. put him back for water break and then when he starts biting again hes ready to go some more. it can cause brain damage %26 misaligned teeth when excessive and this is an easy fix. $5 for the ball @ petstores, even walmart.

My hamster once had a minor cut. Nothing happened to him. But if its big, i suggest you take care of it immediately.

Well, I think I would be more concerned with the extent to which he is biting his cage. If he is hurting himself, he may be stressed, or bored. Does he have plenty to do? Does he have play items and plenty of room? Usually a small open area on the skin won't cause a problem, though infection is possible. Is he scratching himself? Check for fleas. If the problem continues, you may want to take him for a check-up.
