This is the organization where I volunteer on weekends. We rehabilitate orphaned and injured animals and release them back into the wild. We are non-profit, and because of the El Nino southern oscillation and increased rainfall, we are about broke with all the animals we have been getting in.
Yes, we have a couple that raises opossums at their home with permits provided by the organization. We don't have the property to raise all the animals we get, so people have volunteered their land to build enclosures and aviaries while animals are waiting to be released.
And you should know that it is very rare for opossums to carry rabies. They are not considered a common vector.
I did a little armadillo research a few weeks ago. We were camping in a state park and those damn things were everywhere. Pretty tame too, not terribly afraid of people. In addition to the leprosy stuff the north American dillos don't really roll up for protection, but they're know to jump straight up when startled. One reason so many are hit by cars.
My wife got a great video of one eating some dropped bread about three feet from us. I'll see if I can get it posted.
