It means it feels uncomfortable. With hamsters, biting is used as self defence. I had a hamster, and when I first got him he bit me a lot. The proper way to deal with this is the following:
1) Hold him every day to make him feel secure (Make sure you are carrying all of his legs).
2) When he bites you stay calm and don't freak out, just try again (Screaming will scare the hamster even more).
3) DON'T STICK YOUR FINGER IN HIS CAGE!
4) Cages are a hamster's home, so he may bite you. It's like a giant broke into your home and tried to lift you out of it. So try step 2 and eventually that hamster will get used to you.
there is no such thing but if you mean a roborovski hamster yes its a dwarf
Well, this is how you say dwarf hamster in japanese- ドワーフハムスター
If it's a dwarf hamster, it's just boxing. The species tends to do that. It's just their way of playing. If it's not a dwarf hamster then that's strange behavior but i don't think it has rabies
It likely means that maybe your male hamster is not a male,its a female and she is pregnant
that some thing is wrong , probably with its kidney's.
Sure! I have a hamster & it could also be mean by biting you. The same thing for guinea pigs, too.
That depends on what you mean by White Dwarf Hamster. You may be referring to a Winter White Dwarf Hamster which tend to be a light gray, or a Albino Dwarf Hamster that is completely white and maybe red eyes. Albino Hamsters may be hard to find, but you can call nearby pet stores and ask if they have the hamster you are looking for. (Stores like Pj's Pets, PetSmart, Local Pet Breeds, etc)
Just getting more info about you, or licking salt from your skin.
It means it is getting used to it new home.
Your hamster is probably a russian winter white dwarf, they change color when it's cold.
SYRIAN HAMSTERS SHOULD NOT BE KEPT TOGETHER
by normal, if you mean sirian hamsters then the main difference is that Chinese hamsters belong to the dwarf hamster species, which are considerably smaller and arent as friendly (believe me, i know, i own two!).
