I was shocked when my mum told me for the first time, and i too see it with my own eyeballs. They don't piss and poo everywhere, just inside the toilet, even though no one taught them where to relieve themself. One of the cat dislike ppl grinning like an idiot infront of her, she'll happily give you a tight slap. Been there, done that, a few scratches as a lesson on the cheek. My mum also happily declare one of the 3 seater sofa as their rest area, there goes my weekend nap spot. No matter what, they won't budge even though you force yourself to sleep there, they'll sleep 'on' you.
