While Iguanas consistently top the most popular pet lizard in the reptile hobby... they probably shouldn't! Iguanas can make excellent pets, and we at Pet Central actually have an Iguana, "Keith", as a store pet who is the best lizard ambassador to exist!
Iguanas get big, need a lot of room, eat a lot, and most importantly are very commonly quite aggressive. They can make awesome pets for the experienced reptile keeper!
