Wednesday, June 17, 2015 The Nugget Newspaper, Sisters, Oregon Tales from a Sisters Naturalist by Jim Anderson Opossums and cats in the news The other day an email arrived in my in-box contain- ing a message from a Sisters resident who was wondering about opossums in Sisters. She wrote: “My horse is showing signs of EPM but there aren’t opossums in Central Oregon. The EPM is contracted through eating opossum poop, and I get my hay from a grower in Sisters.” EPM, Equine Protozoal Myeloencephalitis, is a dis- ease that affects the central nervous system of horses. It was first discovered in the 1960s, and considered rare, though recently, an increasing number of cases have been reported. Early research in the Southeast U.S. identified the opossum as a host of the disease. However since that time it has been learned that all wildlife can be a host and vector, but it’s spread mostly by outdoor cats. As an example, horses in the Rocky Mountains have been found with EPM where no opos- sum has ever lived — but just about everyone has a “barn cat.” And here it is in Sisters, where no opossum have ever lived either… The villain is literally underfoot, rubbing on the horse-owners boots. Outdoor cats are more trouble than they’re worth, and they spread some very nasty dis- eases in their poop. So much for that; let’s talk about opossums, the only native marsupial living in the wilds of North America. They are confined to the east and southeastern latitudes, and transplanted to the humid Northwest. When I worked with OMSI in Portland and lived in Beaverton, opossums became part of my life, being underfoot (literally) 24/7. I had a U-pick farm in Beaverton and had to deal with opossums getting into my pickling cucumbers and cornfields. They also made themselves at home with the food I gave my goats, geese, and chickens. I began won- dering what they did for a liv- ing in and around Portland. To help find out I placed a small, numbered plastic tag in the ear of every possum I came into contact with and released them. People called me with opossums in just about every kind of human contact you can think of, so to increase those contacts I asked the Beaverton police department to give me all their opossum calls, which they were delighted to do. The best one happened one night when the duty offi- cer asked me to come to a home in downtown Beaverton where a resident was com- plaining about “burglars” in his home. I got there just in time to hear the home-owner say, “I tell ya’ I can hear them in the walls trying to get in my house!” The officer in charge looked at me and I asked the fellow where he could hear them. He marched us off to a hallway and kicked the wall with his foot, “Right here!” he said. I dropped to my knees (it was a lot easier back then) and took out my stethoscope and listened to the wall. He was right, I could hear all kinds of bustling behind the sheetrock. “Yep,” I said, “I can hear ’em too.” And with that the guy took his jiggle- saw and proceeded to cut out a suitcase-sized piece of the sheetrock. Two things happened almost simultaneously as he cut the hole in the sheetrock: first, a huge mass of plastic bags came tumbling out of the hole, and at the same moment one of the officers investigating the back- yard shouted,”Hey, inside the house, you gotta come and see this!” We all hurried to were the officer was standing, and in the light of his torch we could see 40 or more opossums headed right for a bunch of Volvo cars and sta- tion wagons filling the backyard.
