I have lived in the country my whole life. Pests and varmints are a way of life out here. This 'possum comes acallin' every night. We have 13 outdoor cats, they require a fair amount of food to maintain but we don't have a serious rodent problem either. We will be lucky to have 5 by spring. We do have a few marsupials who enjoy a cat food meal yet return only used cat food..they don't do anything but eat free lunches, defecate, and screw. They are a necessary part of nature, their job is to clean up messes no other creature larger than an insect will touch. They do this job happily, but when I am buying the food, the recipient must be returning something. We feed the squirrels and birds for the pleasure of seeing them. There really is no pleasure in seeing a 30 pound rat eating food I paid for and leaving a giant human sized turd on my porch. Now opossums are fairly docile (read stupid) and slow moving. In the past I would have quickly dispatched this interloper without even a second thought. Last winter I found 2 on my porch eating cat food. I retrieved the shotgun and they didn't return again. After that I felt bad for a day or two. This was the first time I have been remorseful about killing a pest. Now don't misunderstand, I have never went looking for things to kill (with no intention of eating it)nor have I ever taken pleasure in doing it, it is just a reality of country living. We kill our occasional coyote, opossums and skunks. Now I am devising a plan to relocate this critter rather than killing him. I don't know what to attribute this change of heart to...maybe age breeds compassion?
