Your wife must have really known what she was doing back then. These are not the iguanas that occupy so much of our efforts on this forum. I think that's mostly because the Cyclura are so easy.
Well, to me it's obvious you have Cycluras, like Cuban Rock Iguanas. Or Cyclura nubila caymanensis'. I'd love to have a Rhino. Can you send a baby to me?
They are all well known for being very mellow and friendly if you give them half a chance.
If you had Iguana iguanas, the typical pet store $30.00 iguanas, you would have a whole different story LOL!
That one who knocks on your door? You just have to sit down with him and have a talk about respecting one's parents.
That "albino", could be worth thousands. Is it an offspring from an original pair? Are it's eyes red? That's true albinism.
Why don't you have the females spayed? Isn't keeping several just an awful lot to do? Or are you in business with these guys? On a down note, I'm sure it's obvious to your wife that inbreeding will start in if you let the babies mature and mate with each other.
Giant Green Iguanas (Iguana iguana) CANNOT live together, no matter what. A few might be able to pull it off, but that's bad information to all the paired and tripled iguanas who rip each other to shreds.
