Crazy Iggy!  

Could he be hungry? This may sound strange but try putting some warm water in a spray bottle and spray him. My iguana loved to be sprayed. I read somewhere that you should do that anyway. It puts moisture in their air and they are used to warm tropical environments. How old is he and how long have you had him? Mine used to ram his head into the side of the cage but that was because he was trying to get my cat.

He's probably Horny. Needs a little Iguana love. I'm serious about this, not sure how to solve the problem just let him get over it i'm sure like all of us he will relax eventually and accept his fate

Are you 100% sure, he's a he? I ask because I have a female iguana and during this time of year she will do anything to get out from where she is...and she's free roaming and has TONS of room. She is going though a period (usually from November-January) where she wants to prepare a place to lay her eggs. When she was younger, she would lay at many as 40 eggs. Although she hasn't laid any eggs in a couple of years (she's 10 years old), she still goes through this ritual every year.

Does he give you little HEAD-NODS? And does he flare his pouches at you?

Sometimes, iguanas will react to different colors. My iguana would get angry at certain shades of the color red for some reason. He liked to climb up on my red towel and sit.

This may be a male agression issue, or a territory issue, or a cage size issue.

I think you might want to let him out to roam around your house.

Give em room to roam...

You got lots of good responses on this one. You might also make sure his temperature is correct. If he is too hot, he may be trying to get out of the cage.

Google "Melissa Kaplan." She is an expert on the care of iguanas. She also wrote the book "Iguanas For Dummies."

Another good site to look at is iguanaden.org

Hopefully you can find more ideas as to why he might be doing this. Be careful and watch him closely. Iguanas are hard headed, persistent little buggers. You want to make sure he doesn't cause any damage to his skin. If he repeatedly bumps or rubs the side of his cage, he can open a raw spot, which can cause all kinds of problems.

Good luck, & keep up updated!!

not sure either but you should have a pan of water in his cage for im to poop in and also with males if a lady in the house is in her cycle a male will sence it and act up our males do it all the time We read that it is normal behavior also just a suggestion
