My cat refuses to learn that she has to paw at the litter instead of the side of the litter box, the mat outside the litter box and the wall next to the litter box in order to bury its crap. Also that when I yell at her and she tries to escape the better route is the one that is easily available farther away from me on the other side of some piece of furniture instead of the narrow space between my legs and said piece of furniture. Also that she shouldn't headbutt as hard as she can the scoop full of kibble on its way to her food bowl. Also how to actually meow instead of chirping and bleeting. And, yes, she gets under foot all the damn time.
This cat is f'ing stupid. My other cat got taken to the vet yesterday and was away for about 9 hours. The f'ing stupid one's been hissing, spitting, growling, screaming and snorting at the other one ever since I brought him back.
