I have two new guinea pigs. They are still nervous so I've just been feeding them and making sure they have fresh water and hay. I feed them pellets and I've been giving them carrot, cucumber and red bell pepper and today I gave them a bit of apple. They are eating really well, eating tons of hay and they seem happy and a bit more confident. The one is hiding a lot and I've not seen her drink. I cleaned out their cage today best I could and saw she has diarrhea and where she has been hiding is a big patch of it. Should I get them to a vet or will is stress them out? Will it go away by itself? Am I feeding them too much/the wrong things? I've heard some GPs don't last long once they have this especially with not drinking? The other doesn't have it so could she just be stressed from the new environment etc? Any help would be appreciated, thanks.
