awwww. poor kitty! No concept of the laws of physics -- probably because cats are convinced that they define the laws of physics as they wish. y'know, that would explain quite a lot about the various crashes, thuds, and thumps produced in the middle of the night when he knows I'm not watching him embarrass himself and doesn't quite grok that I still have ears... XD
My cat had 5 years of belonging to people who thought it was just fine for all 3 of their cats to sleep on their bed because none of them was allergic. ^^;; I managed to keep my cat out of my room for the four longest months of my life, until I'd mostly gotten acclimated to him, and since then whenever I even try to close any of the doors he sets up the howling. Of course, I'm fairly sure he was abused as a kitten and then thrown out, given his combination of PTSD and abandonment issues, so I try to make allowances there.
...And then there's the brain-lock when it's 4:30 am and you've been abruptly woken by fangs-and-claws wrapped around your feet in all directions at once and the only thing your brain can process is 'play DEAD, or else he tries to kill the big scary rodents under the covers some more.' It usually takes me at least a minute or two to recoordinate enough to keep still AND yell 'no' at the same time. XD And by then he's convinced the not-moving feet means he's done his job and vanquished the foot-size bed-rodents...
