Hi! I have two guinea pigs and I've noticed that one of them poops a lot less than she used to. The poops themselves look super healthy, but I'm worried why there aren't that many of them. I used to have to spot clean the cage twice a day, (it's fleece) but now I could get away with every other day. She doesn't seem in pain at all and still eats fine and is active. I would also like to point out that her and her cage mate both rub their bottoms over the floor or their pillow sometimes. Should I be worried? Thank you.
