i have seen one spider who had bad 'wobbles'. i have seen 100's who have none at all. i have never heard of a cleft palate in supers. and surely your friends should have been seen by a rep vet before he euthanised(if he indeed did)to make sure it did. as you said he 'thought'.
it really makes me angry when i read people, who probably dont own these snakes, call them deformed. my spider, and any spider i have seen was not deformed, unless you call regular eating a deformity. my super cinny is certainly not deformed, and as i said before my yellow belly has this head, but my black pastel does not. funnily enough both the yb and the sc are prolific feeders too.
maybe the kinks in the caramel should be brought into this, as i would imagine kinks to impair these more. or the albinos eyesight.
it also makes me very angry when i read of people thinking snakes are disposable, that really annoys me.
