These are animals not gadgets. They do what they want when they want. If he's hungry he'll eat if hes not he won't . My cham sleeps hanging from his tail at night which isnt normal but he likes doing it.
some people feed every day, some feed every other day. There is no wrong answer. As already stated, its important not to overfeed. I feed 3 to 5 cricks or the equivalent in other types of feeders every day. Some feed 6 to 10 every second day.
I feed hatchlings at least once every day as much as they will eat in a couple of minutes leaving a couple of extra crickets in their cage since they are growing. Once they are about 3 or 4 months old I feed them every second day as much as they will eat in a couple of minutes and leaving a couple of crickets in the cage for later. I continue feeding them every second day from then on except for during the winter when its cooler and their metabolism slows down a bit...and then it could be that they will get fed every 3 days. There's no set rule. I just don't overfeed them constantly and I don't feed them if they are getting fat. I control the females' diet more than the male's too with the hope that they will not lay big clutches....or maybe not lay at all.
i have a male adult chameleon and i have been speaking to a chameleon specialist in the uk and he told me its fine to feed my chameleon everyday but i keep reading on here that you should on feed him every other day???
