I was always blessed that both my kittehs enjoyed, or at least tolerated with good grace, tummy attention. Rubs, snorgles, face squishing, all were good. Especially if they weren't really required to do anything except lay there.
Leia had the most amazing shading on her tummy. I never was able to take a picture that fully captured the way her cinnamon underfurs looked, but trust me, it was a natural work of art.
She enjoyed the admiration, rolling and stretching and showing off her loveliness.
I miss them.
