I'm a little worried about this too. I know this is an older post so maybe you can help me out

I've had my BP for 9 days; he's been fed 2x (yesterday was his latest meal) & no signs of any poop/urine at all. I'm hoping maybe he's just using his meals to put on some weight & might not need to go. He looks healthy, but maybe underweight for his age. He hatched 10/28/14 & his weight at shipping time was 140g, which seems a little low for almost 7 mths old.Haven't weighed him yet, but a scale is on th way. What do you think?
