I have two male guinea pigs and I’ve noticed one or both of them have been having very wet poops like diarrhea. This started a couple of days ago and I haven’t been able to tell which one has been having this issue. I have seen them both have regular poops since I first noticed this, but I keep finding dried up spots of what looks like diarrhea in their cage. I feed them an unlimited supply of oxbow orchard grass hay, oxbow adult guinea pig pellets, and a handful or two of either spinach or a spring mix lettuce per day. The only thing I can think of that could be causing this is I recently changed their pellets food. I have always fed them oxbow pellets but a little while back I had to buy a small bag of kaytee pellets as I couldn’t find their regular food and they needed more. I just switched them back to the oxbow pellets about a week ago so that’s why I feel like the pellets might be causing this. Should I continue to feed them the pellets and hope that they just need to get used to them again or could there be something else that might be causing this? They’ve never had this issue before so I’m not sure why they’re having it now. Any help would be great!
