AP has nice 6x2x2 cages that I have my eye on for my boas. I'd get the heat cable and also a RHP to keep the ambient temps up. I'll get the shelf for them to climb and thermoregulate on and also will get the glass sliding doors cause a boa will pop out the plexi doors. They are not cheap and shipping is a bear, but they are great and given the number of years a boa will live in one I'd say it's pretty cheap real estate ~this is how I presented it to my hubby!
