My hamster is shaking really badly, he was fine this morning but now he is shaking and walking on three legs and he almost fell off his shelf. I put my hand in the cage like I always do and he growled. Hes never done that- he usually runs right on it and waits to be cuddled with. he is a russian winter white and hes 4 months old, he never done that before!!! help!
He may be in shock from possibly allergies or a big scare if you started feeding it something new that may have been bad. talk to a vet and see if this is normal.
Has your hamster been in his cage the whole time? Are you POSITIVE no one took himn out and dropped him, he probrably growled at you because he's afraid you'll hurt his leg, call your vet .
well thats not good... :-(..... maybe hes cold
