Because it thinks it is going to be attacked. let it smell your hand from outside the cage before you put in the cage
maybe
if you just got a new hamster leave it alone for about a week, then you can start to put your hand in the cage and let him smell you. slowly you can put treats in your hand and if it trusts you it will crawl on to your hand and take it...even if your hamster is not new this is a good way for your hamster to trust you, and become friendly
you put it in the same cage with a male hamster
(It would not let me put commas.) broken-- hamster cage--
Yes, it'd be best for the new hamster who is coming in to the cage. And would be much more sanitary.
Put a hamster of the opposite sex in its cage.
Yes you can
In a hamster ball.
If it is a new hamster then the best way is to put your hand it's the cage with a treat on it, if the hamster takes the treat and quickly runs away this is fine. Do this a few times every day and you should soon be able to start picking your hamster up without any treats. If hamster bites you whilst you pick it up this is probably because they stressed, or nervous, so just put hamster back in cage.(Don't shake hand to try and get hamser to release grip as you may injur hamster).
in its cage i say. i have a hamster and i have to go to school, i feed him in the morning and i leave him in his cage, when i come back i put him into his exercise ball , and then i feed him again.
Put your hamster's cage in a cool place but also where it can get sun. Make sure not to put it directly in front of a window and not in a closet or under a bed. If you have cat's it's a bad idea to put it on the floor. My hamster's cage is on a shelf up high. Have fun with your new hamster!
Your hamster is showing that he doesn't like you at the moment. Feed your hamster through the bars of the cage with his favorite treats. bring your hamster to the vet and ask what to do to make your hamster more friendly towards you.
