Possum tastes fine. Haven't had it for years, but here is what we used to do.

If you trap one first step is to put it in a cage and feed it table scraps for a week)they are known for eating roadkill).

Then clean it and boil it whole for an hour.

After that we would cut it up into 4 pieces and put it in the slow cooker with whatever was handy - potatoes, carrots, onions, etc.

It was good that way - the key is to boil off some of the fat.
