When I got Stewie, his poops were huge. I mean large in circumference and long. About 6 months ago, I quit seeing these in the drop pan. I figured he was pooping girl size poops. Then I noticed smaller poops...

I didn't think anything of it till I was clipping nails and noticed when Stewie pooped they were individual small oval pellets coming out, sort of compacted together when he pushed them out of his cloatia. He doesn't seem to strain at all, just small poops.... Should I be concerned?

Right now they only have an open water source only that is changed daily.

At home I provide water silos. I haven't ever used water bottles(I did back in the beginning- long story) . Maybe I should along with open water source for him?

I provide a water bottle and my food dish is divided so I put water in one section, Plus in one and salad in the other.
