When Marlin was surrendered to rescue (I was his foster mom for 5 months), he came with a comforter. I was told he knows he is only permitted on the comforter -- on the bed, sofa or floor.

Almost a year later, I am still lunging his darn comforter around for where-ever he wants to sit. He picks a spot and woofs! until his comforter arrives. He was well trained; and now he is training me!
