wont eat,

[samurai]

My corn has never refused a meal before but i just tried to feed him and he will not eat it. I even danced it infront of him for 10 minutes. his red is looking a little pink so i think he is going into a shed but he has eaten just prior to shedding before, i left the mouse in his enclosure, my question is how long should i leave it in there for before it starts to go "bad" if hes not going to eat it i would like to freeze it for after his shed.

Thanks for any help,
