I have several possums that roam my farm and come up to the house. They, like coons, are scavengers. We have one that is missing his tail completely. We nick named him stubby. He is a beta possum. There are some alpha possums running around that he is scared of and will retreat and leave the food he was eating when the alphas approach. My wife dumps all the food scraps out in the front yard. About dusk, they make their daily trot up through the yard to see what kind of treats they can find for the evening. We have several large coons that roam, too. As long as they don't bother anything around my house or out buildings, I leave them alone and let them do their thing.
Now, Squirrels, on the other hand, I have a total hate/hate relationship with those bastards. They chew on anything and everything, from steering wheels on equipment, to fuel lines, any type of plastic body panels to siding on the barns and anything else they decide looks like something they can hone their teeth on. Living in 25+ acres of mature woods, there is a never ending supply of moving targets.
