Move his cage (With the hamster inside of it!) to another part of the house.
put him in a sibling's room if you have anyi used to have a couple of parakeets that lived REALLY long (too long) and hated everybody
it's funny because within the first week of getting a dog one of them died, and the other one died probably 3 or 4 years later, but they were the same age.
