But this would happen if they are given proper care, enough food, and a place with good air circulation and lots of sunlight.

Most iguanas are herbivores while some are omnivore or carnivore depending on their habitat. Terrestrial dwellers are carnivore, they eat mealworms and wax worms while the forest and tree dwellers are herbivores, eats young leaves, flower buds and fruits.

How will you know if your Iguana is growing properly?

Hatchling usually measures for about two and a half to three and a half inches snout to vent. When it reaches and emerges from the egg it grows three-quarters of an inch a month for almost three months. The growth of young iguanas slows to a half when it is three months old with a snout to vent of five and three-quarter inches. Iguana reaches for about 9-10 inches stout to vent in just one year.

The growth of your iguana in this stage is very fast. During its twelve to fifteen months, it will grow for about triple of its original length. The growth length of iguana slows radically as the iguana continues to grow for next years. This time give your iguana a proper diet so that it would not get bigger and bigger.
