Possums are cool. I took care of a baby possum once. If you set out two bowls of water, they’ll use one as a toilet. It sounds disgusting, but actually, it makes clean-up very easy. Just dump the mess in the toilet.
I had a cousin that caught a mama possum with babies attached. He wore the babies in his hair for a few minutes before returning them to mom and releasing them.
I have heard that one should avoid putting two male possums in the same enclosure, as one of them will bite off the other one's tail.
