When I used this, the mouse would always escape because his tail wasn't going all the way in so the door was held open for retreat...I cut off the end and fastened a jar to the end and it worked... the mouse went all the way into the jar and could not get out the door flap again. Wish they'd make it with a big receptacle at the far end that would detach for dumping.

I have used the "Mice Cube" for at least a dozen mice and never had a problem with a mouse dying from lack of oxygen. 11 hours? Might want to set an alarm.

I bought your "mice cube' it is a really good idea however I drilled 3 holes into it to allow for breathing and after 11 hrs mouse was gasping at one of the holes. I would suggest you produce this item with air holes in it In order to save life of mice. Mouse went into it at 8:30 pm and I wanted to.let it go in field nearby in the am.
