the spider wobble

[Kinalyx]

i guess this is moderately off topic, but i was wondering why its consider "normal" for a spider to have a wobble, or even a major wobble?

I see carpets going for as little as half price due to a slight wobble, theyre considered to have neurological issues, while spiders have it all the time.

I guess what im asking is, are spiders neurologically inferior to other balls, or other snakes in general.
