Our cat was hit by a car last week, and the vet has said to keep her on 'house arrest' for a few days until her legs are less lame. So she's having to use a litter tray again.
Two days ago, DH had a moan that the cat had missed the litter tray when she peed. Thinking nothing of it, he cleaned up.
Today, I heard a shout of 'Oi, you silly dog!' and the door swiftly opening. It turns out that our dog had cocked his leg to pee into the litter tray 
.
I can't be angry with him, it's genius! Talk about jumping on the bandwagon.
