How often do leopard geckos defecate?

[Knash14]

I recently bought a adult male leo from a reptile show, talked to the breeder and he looks fine with a nice fat tail and is active at night walking around sometime during the day to switch hides. In the 2 weeks that he has been with me he has only defecated once. I've also never witnessed him eat anything that i've left in the terrarium. Meal worms, wax worms, crickets, dubai's, nothing he has gone right after.

He needs a little time to adjust, althoug 2 weeks seems like way more than what I have witnessed they take in order to adjusting, my best guess is that something is wrong in his setups, (maybe temperature) and it is causing him to lack apetite, and, if he doesn´t eat, he doesn´t defecate much (He should defecate every now and then, you said he has done it once, it also seems like a bit too little, has he passed urates??), could you post a picture of him and his set up??
