son of a BITCH part 2

My apt has two litter boxes- one in the bathroom, one in the spare room. When darwinfail cat is locked in the bathroom, the door to the spare room must be open so auxiliary backup cat can reach the other litter box. When darwinfail cat is not locked up, the door must be closed, so that he doesn't wander in and pee two feet away from the litter box. Last night I mixed up the order, leaving auxiliary backup cat no where to pee but my biking shirt. On the couch.

The good news darwinfail cat seems to be taking to the new litter just fine and hasn't had an accident in days.
