Our girl will hold hers until we take her outside whether it be 5 days after feeding or 15 days after feeding, during the 2 weeks of ghastly weather we recently had on the Mid North Coast we were unable to take her outside at all but in this time she had had 3 medium rats, when we were able to get her out in the sun the 1st thing she did was poop and it looked funny almost artistic lol it was urate, poop, urate, poop, urate, poop looked just like all 3 nicely digested rats 1 after the other....never ever defecates in her enclosure, don't blame her it stinks big time.................................Ron
