Well,..under normal circumstances in nature, young rossalleni would no doubt be consuming anoles on a fairly regular basis, and I've even been quilty of feeding a few Anoles to snake's that I've had over the many years I've owned them. But in all actuality, lizards can harbor substancial amounts of intestinal parasites that can be transferred to your otherwise healthy snake.
This can even be a potentially bigger problem if you live in or around the city where many pesticides are used in the area for insect control, as lizard's consume vast quantities of insects that can have some exposure to these chemicals.
The bottom line is, with all the availability of rodents from stores, and on-line frozen sources, it really isn't worth the risk in my opinion.
BTW,....that's a SWEET looking Everglades youngster!
