Chubby Russian Dwarf Hamster

My Russian Dwarf hamster use to look like this: obese. Yeah it is kinda cruel but I have no idea why he turned out like this. I keep him in his ball 15 minutes a day and I teach him to jump over Popsicle sticks everyday. Now he is "normal" again and I didn't do anything to change his diet. Oh wells, all is well.

Check him out on my shop here:
