I blame the snaffoo. (They have not forgiven me for allowing their stories to fall by the wayside. I will return to them someday.)
Oh, and the new kitty has a name. The children decided that she is to be called Sesame (not my favorite, but all three were in agreement so Sesame it shall be!)
Sesame and Tiger are getting along better than I expected. After one day of annoyed hissing and grumbling, Tiger seems to have resigned himself to Sesame's presence. He tolerates Sesame when she curls up next to him and occasionally plays with his tail. She's a sweetheart, and I'm happy to have her as a part of our family.
