They're so little! I live in Kentucky, where we have really large opossums (pronounced in the local dialect without the first "o") so I'm always surprised to see how cute and little the Brazilian ones are.
Well you may not be able to own them in Virginia (I think the opossums here are adorable!), you could always get in touch with ARK, the local wildlife rescue and become a wildlife rehabilitator. I know they work with a lot of native species. I was actually going to contact the lady I was in contact with a while ago (life got busy and I lost her email) today and try and go ahead with becoming a wildlife rehabilitator soon.
