We've had little Tumbleweed for 2 weeks now and we've started the integration process. He still spends his nights in the spare bedroom with the screen door closed. While it was still dark this morning, I'd heard him playing in there and with the other kitties through the screen door. When I went down the hall to see him and clean his litter box a few minutes later, I didn't see him in any of his favorite spots, so I was calling to him. (I was looking through the screen door.) All of a sudden, I hear his rumbling purr down at my feet on the other side of the screen! How sweet of him to start purring just from hearing my voice and so that I could find him!
