So, Levi, the one who has constantly annoyed me with his frequent pooping, has kind of got me worried, now that I go back and think about it. The first week or so that I had him, nothing. Then I started feeding him (small rat), and after he... uh... exploded all over my roommate's girlfriend, he's been defecating and otherwise at least once in a 48 hour period, sometimes twice. I've seen plenty of posts that say that they usually go once a week, I'm assuming sometime soon after they eat, or even longer without. Anyone have any ideas, and is a vet visit in order, or is he just cleaning out his system or something?
