Out of all of them, the fox is the only valuable animal in terms of rarity. They practically give kangaroos away, while opossums... just find a trashcan.

@MagicalJuko That's not how zoos work at all. You can't just trap a wild opossum and throw it in a zoo. There are very tight regulations on the animals you can display in zoos in pretty much all first world countries. They need to be of a certain standard of health and living, and usually also a registered family line. You also can't just buy them. Zoos almost exclusively loan and trade animals between themselves -- putting a price tag on animals is taboo for zoos. Just because kangaroos are overpopulated in Australia doesn't mean they're overpopulated in the zoo exchange. If you were to actually evaluate a zoo kangaroo for value (which you are not supposed to do) they would go in the tens of thousands of dollars due to their pedigree and health standards.
