About 7am this morning I was woken up by our cat Gandalf running about making a lot of noise .He had already been let out but I soon discovered he had bought back a playmate upstairs to his bed, a RAT & he had lost it under the bookcase.Locked him & the dog outside & proceded to take everything out of the bookcase so we could move the bookcase out to get the rat ,but the rat ran up the bookcase to the top ,where Gandalfs litter box is kept when he can go outside because the dog scatters the litter all over the floor.The litter tray has a cover with a swinging door & the rat went in through the door.husband guarded the door while I got the packaging tape to stick across the bottom of the door to stop the rat escaping .Husband got the job of taking the captured rat outside where he let it go down the street.

It will be interesting to see what Gandalf does to night when he smells rat in his litter tray.
A few months ago we came home to find Gandalf with his paws under the edge of the bookcase & discovered a rat .That one ran down the stairs after the bookcase was emptied out & eventually out the front door with our help.
Once upon a time Gandalf wouldn't come in the doggy door ,only went out the doggy door . Wish he still did ,it meant no playmates came inside.
