I ended up with a 20 gallon metal trash can. Bought a 3" PVC remnant to put in the lid. It should work for both mice and rats...A plastic or steel 55-gallon barrel works fine. No need to put anything over the top. A rat cannot jump out. Some feed or BOSS in the bottom. 20 gallon is tall enough for mice. A board for a ramp on the barrel helps.
