#Patches, Patches,
Showing off your silky underside,
You may look, but don't touch
you tease!

I love how you lumped the chickens together as one pet unit. @manorvillemike might find it harder to regard all eleven cats as one unit.

Math. Sets. You have summoned from the Blackest Holes of my memory a grade school math workbook showing sets and sub-sets. Everything boils down to math. (The chickens boil down in the most delicious way.)

Alas, the memory of circles overlapping with sets and subsets ever eludes me. Might have to go search online for some old grade-school workbooks and revisit this dauntingly dark segment of my childhood....
