I'm a first time Guinea Pig owner, I've had 2 for only a day now. Their names are Reese and Rolo. I've been watching them a lot and I've barley seen Rolo drink. I want to assume I just haven't looked over while he's drinking. I don't know if there's anything I can do to make sure he's drinking or if there's a different way to give them water. They are a year old and have used the bottles that hang on the cage for a long time. I dont know if I'm over worried or if somethings wrong.
