Like the Pro-Ketch Multiple Catch Mousetrap, Pro-Ketch Junior is always properly set, giving you the peace of mind that comes from knowing you're always protected. The tunnel-on-top design of Pro-Ketch and Pro-Ketch Junior allow for fast and easy cleaning, which saves you time and money. The Pro-Ketch Junior also has something new to offer: an easy-view side window! The same perfection as its big brother, only with a new perspective on the live mouse trap.
