I am a guinea pig newbie. We adopted Cuddles and Patches last Sunday from a guinea pig rescue and so far we have all been adapting really well. They are around 1 1/2 - 2 years old and are both female. I noticed today that in their cage they have like crumbled, dusty looking poop as well as their normal poop. Is this a sign of something wrong or could they just be smashing up their poop or something. They typically get Romaine lettuce, green pepper, zucchini, a small carrot each a day, and occasionally tomato and/or cucumber along with plenty of timothy hay and their pellet food. One of the girls, not sure which one, has sneezed once today and both of their noses are dry. Both are eating really well and are drinking lots of fresh water.
