not necessarily, he or she could have a injury. check your hamster for cuts before believing its pregnant.
maybe
It means it prefers the corner of the cage than to its bed. This is nothing to be worried about. (:
no my hamster dose the same and so dose my friends
If you mean whilst being pregnant, she will be alot more aggresive and bite more often and won't like being held or disturbed. She will have lots of babies!!!!
it means if she is able to get pregnant
I also have this problem and have for a while. Just went to the doctor and there is blood in my urine so its possibly a UTI. If your pee doesn't smell right, call your doctor or go to a walk-in clinic.
It could or it could just be injured or have a disease
It means your hamster is pregnant. Take her to the vet to she how far along she is Asap
It likely means that maybe your male hamster is not a male,its a female and she is pregnant
Yes. You should have it in the cage in addition to being in your bed while you sleep. ***** It is not a good idea to have a hamster in your bedroom: Hamsters are more active at night, so having the cage in your bedroom may mean a rather disturbed sleep (especially if it likes using a hamster wheel with a squeak!).
It probably has a disease so you should take it to the vet and clean their cage
Being pregnant, not living like a hermit, is statistically the most common precursor to birth. Your hamster's refusal to leave the tunnel may just mean your hamster dislikes you.
