Its a common occurrence in my house.. and the snakes do it too.. Ha.. But seriously, yeah, its not unusual for that to happen. I give my snake tanks the visual and the smell test every day and if I smell something foul but cant see it, its guaranteed to be in their hide. I wish I could train them to poop in one spot. ha ha. I would make millions!! "Tarzan - The Snake Whisperer".. LOL..
