hi all. my guinea pig used to have brownish poop. today i noticed that it was more towards BLACK than brown and it was partially wet. at first i thought he might of peed on it but i checked and there were no pee stains. the water couldnt of gotten it either. anything i can do or is this normal? thankss. XP Edit: i just noticed that his poop is kinda squishy. gilbert squished his poop! usually its hard...any suggestions on this?
