Despite the fact that Dr. Jones was the most hostile of our cats when Toby arrived, the two of them have become good buddies. I've seen them snuggled together sleeping and they even run around and play together sometimes.
Yesterday Toby jumped up on the bed with Jones and was trying to get him to play. Jones cuffed him on the head several times, which either meant that he was playing along or he wasn't in the mood to play just then. I think Toby took it as play.
I'm glad that Toby has found a special pal among the cats.
