iguanas need about a whole room they are ventours creaters and love to roam but be careful of mals they will jump on the back of your neck and bite and scratch your neck.They love to go for a walk. So take them outside for a walk about 5 times a day.They can get up to 10' long they also get to 15-20 yrs. If this isn't wat u thought u want maybe get a beared dragon or a leopered geko plz take this in conserin

iguanas are quite easy to look after like bearded dragons and leopard geckos, BUT need a a huge amount of space. people that look after them properly give an iguana about half a small room sized enclosure as well as letting them out daily. do alot of research on websites, its hard to write here the exact care. but if you cannot give the lizard at the very least 6 foot by 5 foot space with enough height for them to not have to sit on the floor (they like to climb and rest on branches) then i wouldnt even contemplate it and look into getting a small lizard. if that seems ok then do alot of research.
