Cats

Speaking Cat—Donovan-Style

Boingitykitty: (adj.): Any cat performing the frantic chasing of non-existent anything. This behavior is usually observed in the early hours of the morning, but can occur at any time, especially when you have guests over.
Remain calm. Your cat will return to "normal" when it's damned good and ready and not a minute sooner. Attempts to capture or confine the cat will result in an approximate doubling of the length of the boingitykitty period.

Felindrical: (adj.): Term used to describe the shape of a cat in full stretch of extremities.
Felunking: (v.): An activity in which a cat attempts to explore the deepest recesses of any object or place possessed of an opening large enough (in the cat's opinion) for it to enter. Places discovered during this activity are often used to store favorite playthings and snacks. Felunking is often performed behind appliances, underneath furniture (or area rugs), in closets, and sometimes bedclothes or just-filled laundry baskets which have come from the dryer. Derivative of "spelunking."
If your cat has learned English and has misjudged the dimensions of a felunking site, it may sometimes give itself away by calling for help. "*Meeee-out!*"
Furballistic: (adj.): Describes both the actions and mental state of a cat in the deepest throes of expelling the results of its most recent efforts to completely depilitate some section of its body, usually performed when the cat is doubled over atop your just-cleaned Persian rugs.
Take the rug back to the cleaners and start brushing kitty once in a while.

Kittensmitten: (adj.): The state of a human upon meeting and falling in love with a very young cat.
Kittyinna- Kittyonna-: (pre.): A generic prefix and variant which allows the speaker to describe where a cat is or what it is doing (and in some cases, both, as in "Kittyonnamouse" or "Kittyinnabox".)

Rumblekitty: (n.): Any cat actively engaged in the audio simulation of a diesel engine running with a cold glow plug or two. Experts maintain that this can be a sign of either pleasure or displeasure on the part of the cat.
I personally believe that it acts as an aid to digestion (an important part of catness). At least the cat is not boingitykitty. Enjoy the (relative) peace and quiet.

Snuggleupagainst: (n.): A cat who for some reason has decided not to flop down in a dignified sprawl on your lap (or whatever you happen to be trying to do or read) but is otherwise determined to be as close as possible to you. The word is a derivative of "Snuffleupagus," a character from Sesame Street.
Don't move unless you absolutely have to. The only excuse a cat will actually accept is that the food dish was empty and you were just getting up to fill it. So you'd better actually be doing that.
Sphinxkitty: (n.): A cat reclining in a posture in which none of its feet are visible.
Ask the cat where its feet are. When it looks at you as if you are stupid, take that as an answer and go change the litterbox.

Tummysideup: (adj.): Describes a cat lying on its back, all four paws elevated. Derivative of "Sunny side up," though it is noted that the position is actually the inverse of that described by the etymological root.
Ask the cat if it got the number of the truck. Then scritch tummy until satisfied. (The cat's, not yours.)
