They eat along side my cats all the time and I have regularly had to drag them out of live traps by their tail and other then hissing and showing their teeth I have never seen in aggressive behavior you might want to make sure you have opossums. I was suprised when I started having to take them out of traps that they didn't try to bite me.(Warning do not try this at home results may very,I may just be a opossum whisperer)
may be rabid.
