Caring for a pet iguana requires creating the proper habitat. You should provide a spacious enclosure with heating and UV lighting, a basking spot, and hiding places. Ensure the enclosure has branches for climbing and a shallow water dish for soaking. Feed your iguana a diet of leafy greens, vegetables, and occasional fruits. Regularly clean the enclosure, provide fresh water, and monitor their health for any signs of illness. It's important to handle your iguana gently and safely to avoid stress.
