I do not know
It probably depends on what kind of pet. If it were a dog, there would probably be a lot of loyalty. But if it were a goldfish, conversations would be quite short. If cats talked like they act there would probably be many conceited comments made... but I don't really like cats... Philosophically speaking, some animals would probably speak and reason a lot more like humans then we might expect! For example, maybe some of the more intelligent animals such as elephants, chimpanzees, or orca whales would talk about things that would make sense to humans.
