Alright, vets. Let's hear what should be done for this cham besides putting him in proper husbandry and possibly administering injectable calcium?
And FYI, I went to vet shool, as mentioned above. Even graduated (guess that technically makes me a DVM), but found a much more profitable field and never actually put my vet-ness into practice. So, I'm not some kid with no experience running his mouth.
I didn't specialize in chameleons or reptiles, so I can say with experience that for MBD, besides X-rays to determine degree of MBD and possibly injectable calcium, there is not much more they can do.
Again, I cannot stress enough the point of my initial post (which everyone seems to have missed and taken off with in the wrong direction), THERE IS NOTHING MORE EFFECTIVE THAN YOU MAINTAINING NEAR PERFECT HUSBANDRY. You don't need a vet for that. There is absolutely nothing vets can do if he is kept in poor husbandry.
Or is a vet and her special education and training able to stop MBD for a chameleon who is never gutloaded, supplemented, or provided UVB?
