Glad you caught them. The last thing, especially in a rental, is to have rats get loose on you. We don't have a much of a problem really. The few times I've had a rat get loose, they are confined to the room they are in because they can't get out of it easily. I do live in abject terror though of a bunch of ASF's loose. Roving gangs of crabby small rats with an attitude frighten me.
