They told me she would need the liquid calcium every day for the rest of her life.
Definitely not true. This would not make sense for a chameleon getting the proper gutloaded feeders and the correct lighting. This is done to help a chameleon that has had issues due to husbandry shortfalls, once they are corrected the extra calcium would not be needed. It is done to get them back to the place they need to be, not to keep them there.
