(partially kidding, but only partially.)
I'm starting to suspect that the loudest voices are cats who have either learned to type or to pay for lobbyists, trying to push your feline agenda on the rest of us.
On the other hand, we have to keep the toilet seat down or they'll try to drink toilet water.
I begun suspecting that one day when my wife was preparing dinner. Soon after she took the meat from the fridge to work on it, our baby started crying and making noise for absolutely no reason. My wife immediately dropped everything and went to investigate, and the cat used this opportunity to attempt to steal our dinner meat.
Ever since, I've been noticing many more cases where the baby and the cat are either simultaneously attempting to do things they're not allowed to, or the baby starts distracting us while the cat goes out to carry out some mischief. It's all coordinated too well to be happenstance.
But I have come to believe they are far smarter than me, particularly with scheming methods of sneaking around to quietly appear when they can get food. One used to push donut boxes off the side so that they would burst open, and would then run off with a donut. I have no idea why he wanted to eat donuts. He also tried to eat bread through the wrapper. Or they fein illness. Our one cat had an operation on his leg so we put a little box as a stepping stone so that he could get onto the bed, and then onto the window sill. Turns out he didn't need it at all and could jump perfectly fine, but would still use the box all the time.
They're really clever, just not at jigsaws or sudoku.
The problem is cats are really good at hiding pain - being physically able to jump doesn't mean it isn't uncomfortable or painful for him.
We have a pair of very senior cats (18/19ish years old) and make sure the house has little staircases dotted around to make getting on to their regular lounging spots easier, as we noticed they prefer to use a step if something happened to be available - while they are still fairly mobile, I suspect they are developing some level of arthritis. Given they've been good companions for nearly two decades it's the least we can do to make sure they're comfortable.
Apps which lay their buttons out contrary to the conventions of their platform are evil. Apps which randomize the positions of their buttons are unspeakably worse.
I always, always thought this is what X buttons do, so I was simply closing the tab :))
