Doc forgot to mention that the medical term for a hairball is BEZOAR!
Wouldn't that make a great name for a cat, or a fanfic Kat?

Formerly, bezoars were highly valued (especially big ones from goats, etc)
because of their magical properties. There are even some in the crown jewels
of Britain.

Now how about that for odd?

When a cat sharpens claws, she pulls them off in sheaths. So you get little
hollow claw-castings.
