A representative of the Rodent Apprehension Task Service (R.A.T.S.) has notified us that the 2 AWOL gerbils have been apprehended, and are currently in custody.
The RATS spokesman said that, upon arrival at the containment unit, both gerbils began busily searching for an escape route from the glass and metal-bar cell they were placed in. When one was not forthcoming, one of the miscreants began to try and eat his way out, beginning with the plastic floor in the upper unit; the other began trying to gnaw his way thru the bars.
More details as RATS pass them on to us.
