If I do get another pet or reptile, it'll be a very simple one to keep, like a crested gecko or an African fat tailed or something. This is the first time I had a problem with MBD. Supposedly I have to give calcium to leopard geckos as well, but I raised juveniles with barely any supplements, superworms mostly, and not a single sign of MBD. Same with my Blue tongue (Except he was like 3 weeks old), I gave him (most of the time) canned dog food with mixes of fruits and veggies. Although of course the dog food already has some calcium, so that's helped me. I know canned dog food may be bad with certain ingredients, but I check the ingredients, make sure nothing is wrong, and either way, he's been eating it for about 2 years and 2 months now and not a single problem has happened to him.
Regardless, IF I get another animal, it definitely won't be a chameleon, or anything more difficult to keep in a very long time. For sure if I get something, the only disorder it would have might be because of TOO much calcium. It'll never have a shortage of calcium. Only animals I've been thinking about are either Caiman Lizards (Definitely don't have space for that, not anymore at least) Ackie Monitors (Don't have space either and too expensive at the moment) Cresties (Its a possibility I could get one, but I highly doubt it) Leachies, AKA giant geckos (Way too expensive for now) and Green Tree Pythons (My mom doesn't like snakes, also a bit expensive, can't have it now at least) so chameleons are way off my wishlist.
