Sorry for your experiences, Janice. I have never had an opossum kill my chickens, ducks, or any other thing. I had one as a pet years ago and he was wonderful...I don't have rabies and neither did he. They are extremely gentle animals and I have never had any problems with them my entire life...even before I rehabbed them.
Most of my dogs and cats are rescues from someone dumping them, etc. My great border collie, Dreyfuss was dumped in a freezing irrigation ditch in January in Colorado...the other two didn't make it. I, too, live in an area where people dump animals all the time. As I believe I've heard somewhere around here..."Compassion is not species specific". Opossums aren't dangerous. Rattlesnakes are. We have our fair share out here. I do not rescue anything that could KILL me or my animals. SHEESH the judgement around here! Either way...they found a home. Mary Dudley, LVT
