With a little patience and. The right bait works!

I admit, there was first a few failed attempts with this case. But what is already working at the first attempt? The first two times both bait and Mouse had disappeared and the door had not been closed. The mouse must have been very careful because usually closes the door as soon as the internal bracket will be affected only slightly. Although the door bait The third time was, still in there, but mouse away.
Because I wanted to be honest about to give up. But now I was twice in a row successfully! And that was ME at the bait. In the first experiments, I had tricked a piece of Kekswaffel with chocolate. The mouse could easily carry away completely without coming to the temple. Later I crumbled this waffle. I suppose, by the mouse has remained squatting in the trap to eat there. This it was much longer engaged in the case and so the odds were also significantly higher that it touches while the strap.
Tried it again on the way and I'm sure it works!
That the door halfway stuck I can - at least from my case - not confirm. It is absolutely smooth and even closed, the mouse has no chance to get out again. I can recommend the case fully and mouse inflicted no harm!
