However, the lids of critter keepers are not very adequate for housing a mouse. The lid is made of soft, easily chewable plastic. Mice have no trouble jumping to the lid, hanging on, and chewing their way out in very little time at all. If a mouse decides to do this, it is very likely that you will not catch them before they have escaped. Kritter Keepers can be modified for safety, however. Wire mesh can be cut to line the lid of a Kritter Keeper and secured on, making it so a mouse can not chew out. The mesh can be secured into place with hot glue generously applied, as seen in this picture to the left (click picture to enlarge).
