We got a two month old hamster three weeks ago and did lots of research beforehand, and we have done everything we’re supposed to do - large cage (100cm x 60cm), deep litter layer, lots of hidey-holes, toys, tubes, large wheel etc. We gave him three or four quiet days to settle in and then gradually started allowing a little household noise around him. We put items with our scent into the cage so he’d get used to our smells. Then we started putting our hands in slowly and not from above in case we scared him. Then we started putting treats in our hands and letting him approach to take them from us.
However, even with going so slowly and carefully, he’s still a bitey little sod and regularly bites down hard for seemingly no reason. For example, he’ll take the treat, but before I have a chance to slowly withdraw my hand, he’ll turn back and quickly bite a fingertip (and it’s painful - a deep bite that causes a lot of bleeding and a bruise). Are some hamsters just like this? Should we resign ourselves to never being able to handle him? I would have thought that, three weeks in, he would be a little bit more relaxed :-(
