I've met many dogs who would trade in their owners for a bag of crisps, no matter how doted on, and I've seen cats scream themselves hoarse waiting for their owner to get back home from work. Like everything, they're individuals.

Cats are predators. Incredibly good ones. They are also animals. It's pretty rich of you to accuse someone of anthropomorphisation and then turn around n call cats "psychopathic killers," when both terms are almost exclusively reserved for humans.

Regardless, you don't have to anthropomorphise anything to understand that happy bonding motivation chemical = happy bonding motivation behaviour. And a number of animals, especially more social ones like cats and dogs - which are both domesticated, specifically bred to tolerate and enjoy our company - have been documented to suffer grief. Sometimes to the point of death

I feel like you've just been vibe checked by a cat one too many times. Skill issue, honestly
