I just posted some off my thoughts on this in another thread. I take in animals from time to time, and find them homes. Mostly reptiles. I would like to start a legitimate reptile rescue. Especially bearded dragons. My local craigslists are full of them. And almost all of them are in bad shape. Its amazing to me still, that they are still touted as an easy to keep, beginners reptile pet. I don't have any now, because, to keep properly, 1 bearded dragon takes up as much time, effort, and money [maybe more), than every other reptile in this house.
But, I do have "high end" reptiles, and I do plan on breeding some of these, so there would be a clear conflict of interest if I ever wanted to establish an N.P.O.
Its allot of work, and I applaud you for what you've done. Especially with the animals you've done it with. The mistreatment of lizards is a large problem. And it its almost completely due to a lack of preparation by the owners, then the problems start, and they no longer want the animal, but somehow want to make money on them.
I posted on your thread on your rescue iguana. But if you need help treating his MBD, I can give some good advice, and torn you on to some good online resources.
