A few comments on the foregoing:
Badgers, when taken young and tamed, can be very good pets I have heard although they are rather exigent pets that demand a lot of care and handling.
Dogs are really quite exigent pets in their own right, but we love them so much and are so habituated to caring for them we often don't recognize what a pain in the ass they really are.
It is ridiculous to state that parrots are incapable of affection or bonding with their owners. They can be very affectionate. Cockatoos in particular can become almost hysterically and neurotically attached to their owners, often engaging in self-destructive behavior if separated for any great length of time.
Some fish, koi in particular, can become tame enough act friendly with familiar people.
Some people find creatures like guinea pigs and rabbits to be satisfactory pets, although they do nothing for me.
I guess snakes and lizard can be tamed enough to act docile with familiar people although I don't like reptiles, period.
It is my firm belief that anyone who keeps a pet like a snake that requires live prey has a somewhat sick and sadistic streak in them. I might make an exception if the live prey is something like a brine shrimp or a mealworm, but I just strongly dislike the idea of feeding a living fellow mammal to a reptile, which I suppose is "speciesism" on my part.
