I swear if God exists, he meant for opossums to be pets. They can eat just about anything a human can and then some (though I've heard they have some specific dietary needs if you keep one as a pet), they can't get rabies, they're very docile and rarely bite, they readily adapt to urban environments, and they're very expressive.
The only catches are that A) I've heard pet opossums do have some specific dietary needs, B) their lifespan is like spinning a roulette wheel (sometimes they only live 2-3yrs, sometimes they live 10+, evolution selected for breeding over lifespan), C) they're nocturnal. However "A" could be fixed with opossum-specific pet food, and "B" and "C" could probably be "fixed" with several generations of selective breeding.
