I had no idea that possums eat copperhead rattlesnakes! Wow! I am glad to have them around, too!
I have a lot of critters here, except I've never seen deer in or near my yard. Only the smaller critters. I leave them all alone. I don't mind as long as they have manners and don't destroy my garden. The only critter that I am having a real problem with and have been dealing with them on and off for years is rats! Ugh! They like my backyard because of the fence where they feel safer from larger predators. (Where is my owls when I need them????!) Their newest offense is chewing holes in the screen of my porch to get into my back porch area! Grrrrrrr ......!!!!
