Here's another informative vocabulary lesson to build your FELINE LEXICON ...
From DaisyMae's Feline Dictionary of Terms and Phrases, the phrase of the day is:
MAKIN' INVISABISCUITS (verb) ... may kin in viz uh biss kitz ... A derivation of "makin' biscuits" when a feline kneads a stationary object using his/her front paws in a rhythmic manner simulating early kittenhood behavior with the sole purpose of stimulating milk dispersal from a lactating queen.
When a feline "makes invisabiscuits," s/he is recumbant and kneads the air while purring in a blissful manner.
Note: Invisabiscuits are not to be confused with the very foul and flatulent "air biscuits."
1. When he's especially relaxed (or high on 'nip!), Sparky Fuzzypants likes to tempt Mom to pet him by makin' invisabiscuits and purring like a misfiring lawnmower.
