Exactly! My sister worries that she spoils her dog but I explain that animals aren’t children, we aren’t supposed to be raising them into well adjusted people who need to go out on their own into the world. They’re just pets, we keep them for companionship and joy, and giving them simple pleasures and seeing them happy is the point.
Interesting, I’ve read / heard that cats heal themselves through purring but even that was just a guess with the next leading theory being that they’ll purr when in pain to comfort themselves.
