My two females both have seemed to stop producing stools. its been around 3 weeks, give or take a few days. they are still accepting food and look and seem fine.

my male in same rack is still producing stools.

they are around 7 too 8 months old, male is siting at 474Grams and one of the females is 568grams.

should I be worried about anything, or can they go awhile without digesting and excreting there food.
