YES - I have seen a change, especially in Joxer. His brother and littermate Quincy dies last October.

Joxer has always been the most submissive cat of the bunch. Quincy liked to sleep with us, often next to or on my face. Now Joxer has become my snuggle-baby. He is often waiting for me on the bed, and once I'm under the covers, he walks up (usually on me of course), and is just a purring machine love kitty. He'll sometimes sleep inbetween me and my husband - and is very content. He is a very sweet natured guy.

Joxer also plays more with Jan now. Quincy was her favorite, but she has come to be more playful with Joxer.
