Since all spiders show some signs of spinning (going off of 8ballpython's blog here) is it ethical to keep producing them? A snake that constantly spins in circles probably isn't 100% right in the head.

Do the more intense spinners feed well, poop well, etc. etc.?

I'm not saying its not ethical, I just wanted to hear some thoughts on it.

And I know people love doing animal to animal comparison's so here one is...If a breed of dog showed the same behavior wouldn't people react more negatively to it? I know if both of my dogs started spinning 24/7 I'd be extremely worried about their well being and I certainly wouldn't breed them knowing that their offspring would show similar traits. But then again pure bred goldens are prone to hip problems, bull dogs end up slowly suffocating themselves to death, etc. etc. So...thoughts?
