Wheeeee.... Running on the wheel
My hamster also has a sad story. He was found abandoned beside the rubbish chute on my floor, and been with us for quite a while since (1 year maybe?). His favourite foods include mealworms, jelly (which my fat brother mistook for human consumption and ate some), and drinking loads of water. The foodstick you see in the second photo has been gobbled down already.
Btw in case you are wondering where hamster stays with all the cats, he stays in a separate (cat-free) room. Sometimes, he gets visits from his much bigger feline friends when we open the door. They are always fascinated to see him.
