I wonder if you could measure something like IQ for cats.
We had a cat who literally taught himself how to operate door handles just by watching humans.
Meanwhile, the lovely cat in my pfp doesn't even know that she can push a door open if it's already slightly ajar. She instead tries to put her paw into the gap or just sits there and waits for a human to literally just give the door a little push. I love her but she's so dumb.
