I purchased a Roborovski hamster on the 19th. I let him roam his cage and get comfortable for the first four days before attempting to handle him. As an aside, his current housing is too small and I believe it's causing him distress.
Onto the main topic: I can successfully hand-feed him from my fingers and palm and he will walk into my hand. The problem is that, if I let my hand linger in the habitat or allow him to walk into my hand, he will begin to gnaw at my skin. I fear I may have trained him to associate my hand as food, or I am startling and upsetting him.
He has solid food and chew sticks, but doesn't seem very interested in the sticks. If this behavior is caused by a need for protein in his diet or stress, I'd like to know what I can do to help the little guy out.
