Well I was doing some research on the white ears and they look just like Virginia possums, except their not from the US. Since I've been researching the four eyes for a long time, and they are a lot smaller I think that's what I'll settle on. I don't know, I might just get both. I need to check the Oregon F&W list first though to see if the white eared possums are legal here.

If I do settle on a larger possum it would have a larger cat type cage, with shelves, a hidey box, room to climb etc. preferably at least 6 feet tall. My old Virginia's used to free roam my house, so if I can litter train this one it will most likely free roam during the day and sleep in it's den at night.
