I was thinking the same thing- that it looked more like 2 males doing some combat, but I was giving him the benefit of the doubt since we saw very little of the snake's tails. But you can see how each snake repeatedly tries to dominate the other-pushing down each other's heads. Mating rat snakes are generally far more cooperative-not to mention, successful.
I've bred a few of my rat snakes in the past, & with all that action, they'd have easily been joined up. Either way, it was hilarious that they ended up on his leg, & almost oblivious to his presence.![]()
