I'm sure we all have nicknames for our cats, outside of their actual names.

Buffy is a domestic shorthair, a striped orange tabby. Typical moggie
with an 'M' on her forehead.

Short hair, yes. Thick fur, wow! I've recently taken to calling her
Fluffy McBuffypants. Or Buffy McFluffypants. Either one works.

She doesn't seem to mind.
