I've had several hamsters. A bunch of those cute dwarf teddy bear hamsters. They were fuzzy but tiny. We were given two and one was pregnant and then we had an explossion of them, lol. We couldn't give them away.
Now we have a larger teddy bear hamster. We were told at PetSmart that the larger ones are more loving, or at least, less nippy. Our dwarf ones were a bit nippy.
They all have their own little personalities. One of the dwarf teddy bear hamsters only wanted to eat and sleep and didn't mind being held, she just slept. We named her Pudgy, lol.
The one we have now, is a little escape artist. We've just had to buy him a new cage as he chewed the plastic-metal one. He bent the door lock on the metal so he can open it when my son is asleep. We just had to go out and buy an all metal cage with a special extra lock on it.
