Mouse Against A Mousetrap

Bucket traps may be lethal or non-lethal. Both types have a ramp which leads to the rim of a deep-walled container, such as a bucket.
The bucket may contain a liquid to drown the trapped mouse. The mouse is baited to the top of the container where it falls into the bucket and drowns. Sometimes soap or caustic or poison chemicals are used in the bucket as killing agents.
In the non-lethal version, the bucket is empty, allowing the mouse to live, but keeping it trapped. The unharmed mouse can be released outdoors.
The variations are many with some being single catch and some multi-catch.
