The cabinet could be 20 feet tall and they'd still figure out how to get up there.
My parents have 4 cats and these ones are a lot different than all of the other cats we've had over the decades. My parents have a wall mounted cabinet where the bottom portion is about 5 feet off the ground and the top of it is about 8 feet off the ground. There's about 6-9" between the top and the ceiling, and various decorations up there.. The kitchen table is about a foot in front of it, at normal height, about 3-4 feet from the ground.
One day I noticed one of the cats was on top of the cabinet! That's a good 6 foot jump at a steep angle (100°, 110°? I suck at Trig) and she didn't move a single decoration!
Assuming a cat can jump just over 2m (record is around 7' apparently) then you have a launch velocity of around 6.5m/s. Plugging this in as an escape velocity works out to around a 1-2km diameter asteroid. Not huge, but not bad for a small animal.
My error bars are quite large, so it's only an order of magnitude calculation.
Quick reminder: you SPCA will tell you that a cat living 100% indoors will ensure Kitty and the surrounding bird population are happier for many years longer.
"He rarely goes out" is the worst setting.
Your car isn't somehow special either.
It used to be double. DOUBLE! now it's even worse.
Fuck birds. They should have gone extinct 65 million years ago with the rest of the dinosaurs. This is the age of mammals. They had almost 200 million years (plus 65 million freeloading after their time was up), that should be way more than enough. Let the cats have their fun.
Just in case people do take this seriously, birds are important. If you want to take your cats out, supervise them or put them on a leash. The environment and your cats ARE better off not mangling with each other.
even if you dislike birds, cats don't limit their murdersprees to just birds. they're an invasive species; do yours a favor and keep it in like I do. Their lives are longer and better.
That's the spirit! Let bats take those ecological niches! Bats are cool, and unlike birds they don't go crapping everywhere, they do it tidily in their caves.
Holy shit, is this the reason of "can't decide if want to be here or there, so I must scream", not the wish to be on the other side but the very door itself?
I believe so. Cats' brains seem to be unable to deal with closed doors, in my experience. If you add a passage, like a cat's door to the door, then it's fine.
