My husband and I bought two female guinea pigs from this store. When I got them home I noticed that one had a sore spot on its leg.I called Petco and they said one of their suppliers has a problem with ring worm, yet Petco continues to buy from them. Petco offered to treat my guinea pig, but they said she would have to stay in their care for four weeks! To me that is not a good health guaranty!Be careful when buying guinea pigs from them.
