Ignore the title of this video. These are not “stupid” cats. No–they are cats trying to cope with things that are, well, very hard for them to understand. Clothes dryers and toasters–what sense is a cat supposed to make of them?
BTW, many people report their cats “fold” when they put a harness and leash on them to take them for a walk. But the shoulder harness and leash may trigger the “carry me” reflex that a cat has as a kitten, and his mother wants to carry him in her mouth.
I put a cat harness and leash on my monitor lizard once, so I could take her for a walk; but she bit the harness in half and clearly made known her disdain for the enterprise.
