Chameleons' natural habits make it difficult to care for them. Chameleons are arboreal, which means they live exclusively in trees. They need cages with ample foliage for climbing and privacy, and the enclosure must be quite large. Chameleons aren't that difficult to care for once you've got their setup right.
Once the configuration is correct, it's much easier to take care of them. However, they require more attention and vigilance than most other pets to make sure they are happy and healthy. However, one caveat: Chameleons are very difficult to maintain and inexperienced reptile owners should not start with this reptile. That said, they're not the most difficult exotic pet to care for either.
It's not hard to see why so many people fall in love with chameleons and want to keep them as pets. Yes, chameleons are a bit difficult to care for and extremely difficult if you don't research properly beforehand and buy impulsively.
