7/20: three cats together

I've been a little worried at the changing dynamics in the house, with three cats now rather than two.  The two got along so well, often sleeping together and in general hanging out together.  The new cat is a kitten, so the older cats are needing to adjust to his energy and the kitten is needing to see how he can fit in.  But they were all three playing in the same room this morning and this evening--I'm hoping it's a positive sign for the future.
