Hi colleen, I had an iguana for about 7 years and loved her very much. She loved a dip in the tub. I always ran my tub with about 1-2 inches of water in the lower end, because the tub bottom slants for dranage, and left the upper end w/o water so she could get out of the water if she wanted to. I Would let her swim around for about 20min and then return her to her cage. Do not leave them alone because they can get out. I did this 1-2 days a week and it worked well for me. Best of luck and i think he is a doll.![]()
