Q: I have a young hamster, a month or two old, and he has small patches of long fur. I was on vacation for two and a half weeks, and I came back to find him like this. Should I leave the fur alone? Should I clip it? Is my hamster unhealthy?
A: It is very unusual for any animal to grow fur of a different length to replace fur that was either shorter or longer. Because your hamster is so young, I wonder if you have a “teddy bear” hamster or a breed that grows long hair.
I am not sure I would consider your hamster unhealthy based on some areas with long fur. At this point, I would wait to see if other areas of the haircoat start to grow longer.
In the meantime, look at pictures of Angora or teddy bear hamsters and see if your hamster matches those pictures.
