There are alot of free roamers in the North East. It is the only way you can reasonably own them if you don't have the luxury of living in a Warm State. It is 5 times the work of having them outside, and I'll bet more than one Iguana fan has given-up the hobby for this reason.
Maybe your Ctenosaura are alot smaller in weight/appetite than the cyclura and that has something to do with the amount of feces and odor. For those that don't know, Any animal protien will also make the smell worse.
Some of my cyclura always use the same area, others are slobs -- just like people. I use formica, cardboard, rosin paper, newspaper, straw and alfapha hey to combat this issue. It is a challenge to keep them warm and humidified, without having the area smell.
