Since Tucker's death, Sadie has changed. Of all the cats, she was the most upset with the household changes, and the slowest in accepting Ringo. However, now that she has, they regularly play together. It warms my heart to see them zooming around the house.
Though she is mostly a Daddy's girl, she has started to seek out my lap lately too. I think she is happier than she has been in a long time.
