LOL! that sounds quite useful though really. At least you know when he wants to come out! I've never been able to train a male. For the girls I just put my hand by the bridge and the learn to step on it to come out. Then they just start waiting at the bridge when they wanna come out.
With Harvey he just waits on his bridge and stares at me till I notice, then i go over and lift him off it. If he's not on the bridge (rarely happens!) then I put my hand on the bridge and tap it and he comes running. Then I lift him out and smoosh him to within an inch of his life
