Some people might wonder why their hamster doesn't like to be held or be around you. If this describes your relationship with your hamster, your little friend might be a ghost hamster. You need to wait a a few days before you can determine this though. Some hamsters need to get used to their environment before they will play or be comfortable with you. If your hamster doesn't want to come out, please don't make them. A good way to make sure your ghost hamster is happy and healthy is to leave treats under the bedding and on top of things. If the treats are gone, your hamster is healthy and eating. If your hamster isn't eating anything, you might need to consult a vet. And just so i'm clear, Ghost hamsters are not ghosts.
