You’ve been getting some terrific input already. Pardon if I may repeat some.

Your sweet little girl is maybe somewhere around 4 months or so. I’m not so great at guessing and i can only go by the size of her casque. Right now you should be feeding her once a day in the morning. The amount is never easy to figure for a girl of this age and I probably give a different number every time, but she still has some growing to do. I’m going to say to give her maybe 15+ feeders of appropriate size daily. Your feeders need to be smaller than the space between her eyes, and it’s better to err on the side of being too small rather than too big. Veileds grow very quickly and as young as 5-6 months old she could be sexually mature and producing eggs. It’s essential to get your husbandry as perfect as possible ASAP for any chameleon, but even more so for young ones and our veiled girls. Young chameleons have no resources to fall back upon and if their husbandry isn’t correct in all aspects, they can decline and pass quickly. Right now, I’m going to direct you to the most accurate and up to date source of husbandry.
https://chameleonacademy.com/chameleon-basics/ Do make sure to read thru all and also check out the species specific info for veileds. As you’ve seen, we are a helpful bunch so ask whatever questions you have and someone will do their best. I’m going to search Petco’s website and provide you with links of the items needed. There is still much more to be said about care of our sweet girls, but we have a bit of time.
