Are those meal worms? I didn't know iguanas could have worms...
These aren't green iguanas. They're Ctenosaura pectinata. They take a bit (not a ton so this is a once a week treat) more meat than Iguana iguana. All my Iguana and Cyclura get nearly 100% vegetable, fruit, legume diet. The Ctenosaura get a few bits of meat in the form of worms or crickets each week.
