I already ordered a 24 by 24 by 48 I’m just waiting for it to get here . Is that big enough?I second Remkon. And of course making sure she does not become egg bound is priority. Until a larger enclosure is provided, a separate egg laying area can be provided. I have read of people using plastic trash cans. Not sure how much research you've already done, like thread has lots of info: https://www.chameleonforums.com/blogs/egg-laying-and-the-laying-bin.345/ And the trash can method is mentioned in this thread.
I also highly suggest looking over the care sheet for Veilds, and checking out minimal required cage sizes: https://www.chameleonforums.com/care/caresheets/veiled/
She'll love that! Good size. Pothos is popular, hardy, vining and fast growing. The easiest way I found to pick plants, is to go to a local store that has a nursery section (like Home Depot, Walmart, Lowes, etc) Find the indoor plants section and compare the names to the safe plants list that Fiona's Mom provided. Indoor plants usually do well in the cham cage environment because the are mostly low light.I need help on what plants to buy for it tho
