Theres a very good chance the hamster is very ill. Has he jumped/fallen or hit his head?? There could be an ear infection causing loss of balance and appetite. Try finding a exotic vet near you, or simply call one from the internet that has experience with small creatures such as a hamster! Good luck! Try feeding with a syringe (no needle of course) kitten formula would be okay till he was back to himself. Or fruits and veggies ,
