they grow rather quickly when they are young. How much are you feeding her a day?
Babies grow fast and they need a lot of food. You'll need to start cutting back when she gets to 5 months or so. Overfed females are at risk for larger, more frequent clutches of eggs.
Chameleons in my house, isn't 5 months old a bit early to start cutting back every day? My breeder, Kammerflage Kreations, says to start cutting back at like 12 months???? That seems awfully early. Just my opinion. I guess in the end it all works out.
