So it happens, a little co-worker or at least co-eater :).
Before the dogs get her, I hope to catch the small beast. Idea is simple, mouse smells the peanut butter and runs into the paper tunnel, that consequently turns over and falls down. Mouse caught, still have the peanut butter.
People in Youtube put water in so that they drown, not my mouse, she will be relocated to the neighbors with a wall in between :)
Be nice to mouses!
