And that is fine if that is what works for you, stick to it. More power to ya.
However in 99% of the cases I wouldn't really consider the wobble a health issue. A quirk maybe, but I haven't had any health issues with any of our spiders that was linked to their wobble. Ever notice how people brag about how their spiders are their best eaters and best breeders? Well I will certainly back those people up because our spiders are hands down our best eaters and breeders too.
So what you are saying is that if it has a bad wobble you automatically put it down? Is this anything like yanking teeth out of a rats mouth before feeding it to a snake so it can't bite back? If so I am NOT down with that at all.
Me personally, I don't give a crap what those uptight, holier than thou art jerks at Fauna think. I've met quite a few in person and let me tell you, I really wished I hadn't met most of them. I haven't used Fauna in a good year because of the people there.
