I'm an earth snake. I've had encounters with Pigs and we didn't get along at all, and more recently I've had encounters with an evolved pig and we got along fine.
My mum's a rabbit as well as a few other close relatives. Rabbits and snakes have different abilities and both are needed, so they can be complementary. But also since their very different they can have trouble getting along if there is a lack of acceptance of differences. I just read about it, this says more then I could about computability of snake and rabbit
