i dont know but a mouse that just got grabbed by the tail doesnt sound like a mouse you want to be scurrying into your snakes hide because it scared. i know that your snake is a good eater now but if the snake is sleeping in his hide or just doesnt want to eat that day then a stressed out mouse could be the last thing you want your snake to be in a hide with. just my humble oppinion.

plus, if a mouse and snake can fit in the hide, the hides not tight enough
