The snake passed. It definitely was 1.2 meters (4 feet) or more. Since the cat killed the chipmunks and I'm taking out the habitat and the snakes, a part of the appeal of the yard is lost for me. It's been a long time since I noticed Racoons or possum too. The owl is rarely heard anymore and I haven't seen the hawk alight in years.
I am still excited about the progress on the yard. I have great plans!
