Do Poros have butts?

So me and my friend in a state of philosophical wonder last night came upon the age old question of "where do poros take a dump from?". So of course this led to many questions about poro anatomy. Do they have butts? Do they have ears? We can assume they have noses as we've seen them sniffing things in cinematics, we also know they have eyes, mouths, four legs, and two horns.

I contacted riot support about this important question and got this response "This is Kramsyhr, and I will be your support specialist for today. Hmm, this is really an interesting topic. I have wondered about this myself. I believe they have butts, ears, noses and a reproductive system, however, all these may be covered by that thick fur. Well, at least I do think they have butts. Where would all that Poro-Snax go after feeding it to them in ARAM games?"

Shoutout to Kramsyhr for the awesome response btw. Moving on though, anyone else have any ideas about how poro's bodies may work, or is there possibly a riot member who could enlighten us on this subject?
