When it comes to urates, now that our girl is an established member of the household, she usually leaves urates after about 3-4 days....when we first got her it was literally over a month before she pooped...even now we've had her since Feb 1st and she's pooped maybe on average 1x per month. I think it is really up to the snake - varies greatly also on feeding schedules. When I feed a large mouse I get a poop, when I feed med. mouse I get urates.
