My little dudes will usually each drop 2-4 turds in one "sitting". I imagine they will poop 2-4 times overnight. Often I will spend time with them and they will poop twice in under 45 minutes.
I don't think its a worrying amount. They have high metabolisms and eat kind of a lot of food for their body mass. That food has to go somewhere :p
(Off topic but I hate not mentioning it, try to get pablo a friend if you aren't already!)
