My advice was not necessarily directed toward an extra feeding. As long as the animal is getting an appropriately size meal (I'm a fan of 10-15%), then there should be no reason to feed today and then feed tomorrow. I was simply saying that if you've fed it today and it's next feeding day is 5 days away, there is no need to skip or put it off if the animal hasn't defecated. As I said, I have one that will pass 3 days after feeding like clockwork, and she is getting a 10-15% meal. Meanwhile another one that will only pass after every 3rd meal. (They are MASSIVE.) If I waited for her to defecate, she'd only eat once a month. Both get weighed once a month and are growing fine.
