Depends on how much you feed him/her. When mine were babies it seemed like I was going to the pet store every other day to buy crickets. Then I got this bright idea to order 1000 of them. Big mistake. Half of them died and the remaining stunk up my room. Anyway, I would say start with a smaller amount like 25 or 50 and see how long it takes your little one to finish them. And yes, some of the crickets will die before they become food. Also, toss in a chunk of potato or carrot for the crickets to eat. Good luck.
