Different animal.
Your Opossum is a rodent .
Our possum is a marsupial .
The biggest ones, brush tailed possums are about the same size as a Racoon and have a similar diet, nectar, flowers & fruit.
Really good eating, light sweet meat.
The Kiwi's started farming them to sell the meat to Japan & China as Kiwi Bear.
You could probably get it in the USA, definately in NY.
Fur is very fine and really warm, makes excellent gloves.
Down side is they raid gardens, have very noisy randy fights in mating season & seem to like to hootenanny on your roof at 3 am wearing hob nailed boots.
