My guinea pig scamp has been having smaller than usual poops that are basically two toned- a mix of light and dark brown. The light parts seem pretty dry. Nothing about her diet has changed and she still eats everything I feed her (green leaf lettuce, half a grape, small cucumber slice and cherry tomato and 1/8 cup kms pellets) right away. She seems to be acting totally normal. She's never been much of a big drinker, but I'm wondering if this could be dehydration? She eats a ton of Timothy hay too which she always has access to. Suggestions about weird poops?
