I think this is at least somewhat true--I have two 2010 babies in the house, and they eat every 6 days and poo about once a month. If that! I use newsprint for bedding, and I usually wait until there's at least one poop before I change it out--and with these hatchlings, I swear I wait two or three times as long between poops. AND THEY'RE HUNGRY ALL THE TIME. So I don't think they're constipated/
I can't remember if I went through this last year with the 2009s, because I don't record bowel movements.
