One of my guinea pigs has started having clumpy and mushy poos. I noticed they didn't look quite right yesterday but today it's gotten worse. They are oddly shaped, mushy and sometimes I'll notice big clumps all stuck together. They aren't runny, but they are soft and both my guinea pigs keep stepping in them and smushing them into the fleece liner of their cage. She's still active, eating and drinking, although not as much as usual. I'm going to call the vet in the morning to get her an appointment booked but I'm wandering what I should do while I wait. I was thinking of stopping the veggies and just weighing her daily to monitor how much she's eating? Any other advice would be a great help.
