SUCCESS!!!! This morning we have drifts in front of the door. It's going to take a long time to even get the door actually open, lol. Anyway, I put her in the pen this morning, she sniffed her own pee that I soaked it with yesterday, and TA DA! Instant squat and pee.
Needless to say, she got megatons of love and praise. Zo is now in her rightful place...on my lap.
