You better check that at least every day. When you catch multiple mice, they’ll eat each other. Even worse is when the try to crawl out the very small gap in the rotating mechanism – trying to get a dead mouse out of there is something you’ll never want to do again. Oh, and don’t do this in the Southwest. When you catch mice alive, they end up peeing and that can be a source of hantavirus.
As they say, time flies like an arrow, fruit flies like a banana.
