kitty cat quirkiness

my cat barks at birds, chews through the catfood bag, sleeps under the sheets, plays with socks, can't resist a drawer, opens cabinet doors, puts ponytail holders in his food dish, chases ice cubes, tips his litter box, lies on his back with his feet in the air, attacks suitcases, runs headfirst into windows, and "helps" make the bed. he's never been into milk or fish or any of the human foods that cats typically like - he's a catfood and treats kind of kitty. he's a bit of a loner, but he does like lots of attention first thing in the morning and as soon as his parents get home from work. he's the softest kitty ever and he always smells good (his litter box is another story). he loves to get brushed and he loves to sit on anything that happens to be on the floor. also, he is left-pawed, just like his mommy.
