I don't have a URL accont. How do I post a photo? I needed help identifying a 6' long black snake with some white markings that is in my backyard curled up in a wet piece of swimming pool. I already registered but now I can't post my question! I don't want to kill it but I have 3 cats that go out into my yard and my neighbor has chickens. I have to decide what to do with this snake pretty quick. If it is harmful I need to get someone to do the job. If it isn't I'll let it alone.
