Iguanas as Pets - Iguana Care Sheet - Red, Blue, Green Reptiles - 2019

Iguana care sheet – All you need to know about iguana care

When you are thinking of getting iguana as pet animals into your house, you should be well aware of the rules and general instructions related to iguana care. Iguanas are of different types, with the most common ones being the green iguana, blue iguana and the red iguana. Out of these, the green iguana is the most commonly chosen type of pet. The basic rules related to care and protection of these pets are the same; however, there may be slight changes required in the types of diet and feeding frequency.  An important point that you need to understand is that caring for iguanas is not an easy task. Pet iguana care demands a lot of attention, effort and time from you. It is also quite expensive to maintain an iguana. This article helps you with some of the basic points that you need to keep in mind while caring for your pets.

Cages and supplies

Pet iguanas need a lot of space to move around; hence their cages should be big and spacious. On an average, an iguana cage should be at least 3 feet deep, 6 feet wide and 6 feet tall. You have to follow this size even when you buy a baby iguana because they grow at a tremendous pace. Like most of the other pet animals, iguanas are not very fond of toys. Iguana toys are mostly soft or stuffed animals. However, they don’t get excited about throwing these toys up and playing with them. They like outdoor activities and playing in the water very much.

When you take your iguanas outdoors, you have to use an iguana leash to control them. You can use mobile cages; however, they are very costly and not reliable. An iguana leash, on the other hand, is fit enough for baby and adult iguanas as well. The only hitch here is that not many iguanas may take to leashes pleasantly initially. You need to invest a lot of time and patience in making your pets accept these leashes and enjoy them. This is also an important element of iguana care.

Irrespective of the food that you give them, ensure that they are rich in two important nutrients – calcium and other minerals. You need to remember that calcium and phosphorous should be in the ratio of 2:1 only, at all times. Iguana foods should contain greens, vitamin and mineral supplements every day.
