Ok, this is an odd question. My Pygmies are 4 months old. Their poop is usually very round. Tonight both of them have more of an oval pellet shaped poop instead of berries. In fact, when I first saw it, I thought I had a big rat in the barn, but then I watched both of them poop while they ate dinner, and it was definitely them, not a rat. It looks normal otherwise, no clumping or anything and it has a normal consistency, just shaped a little different than usual. When I cleaned up in the barn earlier today, the poop was the normal round berries. They're on the same food they've always been on, and browsing during the day. The only thing different this week was that they got some Rumatel deworming pellets, but they got that last month too and I didn't notice a difference in shape then, and it's been 5 days ago since the worming, so I would think that would all be pooped out by now. Should I be concerned about the shape?
