When I first got my corn snake, we were feeding her on wednesdays and she would poop the next monday pretty much like clockwork. Then one week I switched her feeding day to friday, and the next week fed on sunday, and it's been sunday ever since. The weird part is, she doesn't seem to poop as often anymore. The first time she missed a poop, I gave her a lukewarm bath right before feeding her and she dropped a fairly normal turd within 5 minutes. This time I've fed her twice, it's wednesday, and still no poop. As far as I can tell there have been no husbandry changes at all. How concerned should I be?
