I’ve seen those. Also bought a trap door type trap to be used with a bucket. However, wife’s cat will not allow samples for testing. Maybe when the cat dies (don’t tell my wife). lolol
I looked at the trap door ones, thought of getting them instead.
However I have a building with red squirrel problems so I am thinking of putting one in the attic there with deeper water.
