I used kale for the longest time... thank God nothing happened(knock on wood). Now I give collards, carrots, butternut squash, the occasional banana slice, and the occasional apple slices. Also, AZ is really hot sometimes, I hope the superworms I ordered will come alive rather than baked to death.
By the way, when people say beardies are hardy lizards, they aren't kidding! When I first bought my now 5 and a half year old beardy, I gave him crickets a bunch, kale and carrots, and calcium, never did I give multivamin until now. Then, to make matters worse, after him becoming 2 or 3 years old, I suddenly had the *****ic thought that he didn't need protein so I stopped giving it to him until now. Lastly, I used reptile carpet for a while but then switched to walnut shells and recently sand. He's an incredibly accurate hunter when chasing crickets but I would still change his substrate to tile if I was allowed to. Unfortunately, due to my current circumstances, I'm not allowed to make the switch. Fortunately, in every other aspect besides bedding, I have since much improved and give him supers, crickets, the occasional waxworms, calcium, herptivite multivitamin, plenty of collards, carrots, and other foods, and bi-weekly baths(and of course a decent
uvb bulb and basking light).
