I have 2 spiders one it bearly knowdess the other I can't even really see it unless he overexcited then I can see a slight wobble, in both cases I have to look for it to notice it. I wanted a text version of the issues so I could print it out for refernce ( myself ) in case I ever loose net and get a bunch of snakes dopped on me again lol so Iknow what I looking at/for to prevent a un needed trip to the vet if just something that happens in that morph. ( like the minor kinks and not freaking out thinking I just had a snake dumped on me with a broken spine. )
