I have what I think is a gopher snake in my yard. I also have round tail ground squirrels and lots of holes and tunnels. Snake went into squirrel burrow and curled up inside. The ground squirrel came and pushed the dirt over the opening. I reopened the hole. GS covered it up again. Haven't seen snake since. Have you ever seen anything like this? Why would a snake crawl into a tunnel with no outlet? Should I assume he is dead? I was so excited to have him in the yard. Thank you.
