Quite a lot of non-rattlers will shake there tail ... I'm not convinced that it's to mimic a rattlesnake, but maybe it's a distraction to the other end to protect its head? Just a guess on my part ...
Barney wasn't fooled though, he could strike faster than this rat snake could, he seemed to think this was a fun new game!
I'm not sure if they actually kill this size, or just play with them ... ?
When I bought this place a bit over four years ago, the basement was over run with mice, and snakes ... I wasn't home a lot, and although I'd trap 8-12 mice every time home, and the snakes obviously couldn't keep up, even with me helping ... Only about half of my house has a basement, the other part has a crawlspace, which has concrete walls, and direct opening to the basement, this little two footer was happy down there ...
I continued to seal up cracks and holes in the basement, one day I went downstairs and found this one ...
It was quite a fight to get it pulled out of the pipes, it didn't want to, but I eventually prevailed, they are extremely strong!
Turned out to be a 5'+ rat snake ... You can see how's it's faking the "triangle head"! I decided then, no more snakes in my house! Ended up evicting 7 snakes, 3 big ones like this!
I got the 4 kittens to not only protect my tractor from mice in the barn (found a nest on top of my battery that was hooked to a tender) but hopefully they would patrol around the house too ... And they do!
Found this one out at the edge of my lawn ...
Once the kittens matured, no more mice, or snakes!
Dug up this nest of copperheads, they didn't like being disturbed! Too bad, they met Mr. Shovel!
