I got up from the couch and had to move Sam, who had been sleeping on my lap. When I came back I sat down beside him as I planned to go to bed soon. But then Boo jumped up and curled up beside me, and given how stressed he had been about Trixie’s arrival, I decided to stay up longer and give him some attention. He was showing signs of accepting her but he was still pretty stressed out about her.
Later as he slept curled up in a ball beside my legs, Trixie jumped up onto my lap. This woke Boo and I thought he’d get up and leave, but instead he stayed, trying to determine what to do, so I stroked his back and he fell back asleep. I got Trixie to lay down on my stomach but then she eased over so that her feet were up against his body, and I was surprised to see that not only did he not hiss at her, he tolerated it without incident.
So she moved a little closer. And then a little closer. She was now partially sitting on top of him, but still Boo showed no reaction. Trixie then eased completely off of me so that she was sitting on top of him, and I was stunned to see that this too he tolerated.
A little too emboldened, she leaned over and smushed her face directly into his. This I knew would be a bridge too far, yet Boo didn’t budge. Given the landmark moment I decided to forgo sleep for a while longer and let them bond, though I kept falling asleep sitting up. Hours later, with Trixie still atop Boo, I relented and went to bed for a little sleep.
They’ve been getting along ever since.
