Hello everyone! I am new to this group. I have two male guinea pigs that are about a year old. I have had them both since they were very young. Vibe is a white crested, and I think that Matrix is a Abyssinian and Peruvian mix. I have a 2by3 C&C cage and I use fleece bedding by PiggyBedspreads. I have been noticing that my long haired guinea pig, Matrix often is moist on his belly. He also keeps getting little dreadlocks in his armpits. Does anyone have any advise of how to avoid this? I change their fleece bedding every three days, I also brush him weekly, and bathe him monthly. I am at a loss of what to do. Any advise is much appreciated! Thanks!!
