Yep, it's a snake!
And we think it was after these cute little things
They were all found out in my parent's shop. The mama cat had moved her babies to a very difficult area for her to get (much less for us to rescue them) and while we were searching for them, we came across the snake. Luckily, my dad took him and moved him out across the fence in the pasture. He was a spreader--acts like a rattlesnake but isn't a rattlesnake. Fun day, eh?
