jerking hamster?

[loveflower]

sometimes my hamster starts to jerk a little.. kind of like he has the hiccups

it doesnt seem to hurt him, does anyone know what this is? is it common?

if hes twitching in his sleep that sounds normal.

also, i have caught mine jerking off before. im not even joking...
