Wow that's pretty amazing. What a great group of vets. One would think Patrick would have trouble hitting prey with his tongue since he no longer has accurate depth perception but he did a pretty good job grabbing a cricket in one part of the video.
I had a panther chameleon that had cancer in one eye and had it removed. It didn't take him long to figure out how to hit the bugs again with great accuracy. Rather amazing!
When he first had the surgery done he walked in circles for about a week..then some how he figured everything out again. I had to help him with the bugs at first too..held them closer at first so he had less chance of missing but it didn't take very long before he could get them on his own free ranged in the cage. He amazed the vet too.
