Sounds You Don't Want To Hear From Your Cat
Kitty Witty knocking a roll of quarters off the counter onto a tile floor at 3 a.m. producing just enough of a loud, unfamiliar scary horror movie noise to make you just about jump out of the window.
The "WTF" meow from behind a closed closet door. The one that sounds like the Furball of Fun is saying "let me out before I go poopies on your new shirt and under a few things you might not find for awhile."
The sliding of claws across wood floors, also at 3 a.m., into chairs, baseboards, etc as little Sweetie Pie has trouble stopping while chasing the toy mouse he just batted across the room.
The shrieking sound Puddy Tat makes as he gets his tail caught in the refridgerator door as he inspects what is in there as you stand looking (hoping) there is something good to eat, but does not move out of the way in time as the door closes in on him.
But the most enjoyable sound:
The purring from Finny Finn Finn Finnmeister Finnigan as he snuggles up on my chest after I get in bed (as long as I get in bed before 3 a.m. play time).
