thanks!

She will get 5-6 feet with tail. It doesn’t matter how big without because you need to account for the tail as well...the top gets thick enough to count as part of their overall size so they cannot move if you have them in a cage too small.

What do you mean spray? Like a cat? Or does she mean pee all over the place? They don’t spray like a cat but they pee with a bunch of force and a lot of it. Their poop is about the size of a small dog or cat when they get big....only much messier. They go to the bathroom 1-2x a day on average.

An iguana is not a "pet" for a child. It will require a very large space, preferably in your own home. A "cage" is good for the first year or so, then a natural enclosure is needed.

Temperment...My alligator is easier to handle than the iguana. The iguana is very ill tempered and, did I mention he’ll poop all over the house?

xta- i cant get a bearded dragon because my mom had friends that had 2 and did not clean them (cage) or handle them and they were mean and smelly, so she is afraid of them.

As for your questions, I didn’t feel like sorting out the good posts from the sarcasm up there so here they are:
1. if they sprey when they pee-
Iguanas pee and poo at the same time and it can get messy, more of a big runny puddle of pee than a spray but a runny puddle still makes a mess when running off a shelf or basking branch. They can be trained to use a water pan fairly easily, or give her daily baths, often times the bath water will stimulate a poo responce. Be prepared to do daily cleanup though or your iguana just may "poopie paint" the entire habitat with her claws and tail.

2. what size cage i need to build (not make into a closet space)
a juvinile iguana needs a cage aprox 4 feet long by 2 feet deep and 2-4 feet tall. An adult iguana if kept in a cage needs a habitat at least 6 feet long, 4-6 feet deep and 6-8 feet tall if you want her to be very comfortable.

3. how much time i should spend with rexanna (i found out that rex is a girl so i named it rexanna! !)
Idealy you should handle her daily if not a couple times a day. Also provide some type of visual stimulation if you can, iguanas see in colour (in fact they see more colours than we do) and love to watch subtle movements like fish in a fish tank or cartoons on TV.

4. how big female iggs get only body.
an adult iguana gets to be 5-6 feet and 12-20 pounds give or take thier tails should be taken into consideration since they are very thick and powerful (an adult iguana can break the leg of a cat or small dog with a well placed tail whip) Green iguanas can also live 15-25 years in captivity with the proper care

5. how often they go to the bathroom and how big no pics!!!
An iguana will usually go 1-2 times a day (hatchlings and juviniles sometimes more often) as far as size goes, trust me you want to train her to go in a large pan of water (like a dish pan or plastic storage tub)or similar. Her poo will be similar in size to a small dog (ie: pug, boston terrier etc) and add up to a cup or more of liquid at the same time that can run everywhere.

6. post your cages please!

Our cages are made from cabinet grade plywood (maple/birch) and coated hardware cloth. A box cage 4 feet wide 2 feet tall and 2 feet deep with wire mesh on top for heat lamps and shelves/branches for basking and climbing works well for smaller iguanas (adults need something much larger) Other options are to convert an entire small bedroom or a large closet into a habitat, using linoleum flooring in the bottom and a wire separation between the heat/UVB lamps and the living area. Remember that a small habitat will not keep your iguana from growing, but it will make it stressed, uncomfortable and eventually sick.

7. what i should put at the bottem of its cage (i got this dirt substitute, whould that be good, you soke it in water and it expands.)

You should not use any particulate (little pieces) substrates because as someone mentioned, it can get eaten and cause a blockage of the intestines. Your best bet is something easy to clean- newspaper topped with paper towels or we personally use regular old bath towels for our 4 iguanas, they are easy to change, rinse off, then toss in the washer with some bleach they also give the iguanas a good surface to "wipe" on which they will do after going to the bathroom. The exception to this is when she gets older and mature (3-4 years) you have to provide her with a nesting box to lay her eggs in or she can become egg bound and can die without surgery.

Yes it is a big book but well worth the read !!!!Patrick’s Iguana Site
