My iguana had cat and dog friends. But this is a neighbor’s cat, and the iguana in this house can’t quite decide what to do. He could charge the cat–that’s sometimes an option for iguanas, and it can be quite scary–but it seems he’d rather not. Note he’s perfectly okay with the dog with whom he shares the house.
And then watch how cleverly the iguana solves his problem. Somebody raised him to be a good boy!
(Iguanas are social animals, and if you want one to be a good pet, you have to bond with and train him while he’s still young and little.)
