I have recently purchased my first guinea pig and I am so happy with him. His name is Kimper and he's still quite young. I bought him from a pet store...I know I know...didn't do my research BEFORE I bought him, but now I know the dangers pet store guinea pigs face...first hand. I went today to a SuperPetz, not the store I bought Kimper from, to buy a little igloo thing for him...had been temporarily using a shoe box for him to hide in, but as you can imagine that was chewed up within a matter of seconds it seemed. Well, I got to the store and decided to look at the guinea pigs for a while. Unfortunately, when I arrived at the "cage" my girlfriend and I were shocked to find a cavy near death. He was lying in the corner with all the others cavies just looking at him. The poor thing was lying there twitching his feet and breathing really really heavy. My girlfriend immediatly called a person over to check on it and apparently there had been no one checking on them all day. There were so many cavies crammed into that little plexy glass cage that I would have been surprised that they would have noticed anyways. There was no hay or anything in there for them. I decided not to do business with them and went back to the place where I bought Kimper...they at least know how to house and feed the cavies as well as supervise them in case of emergency. I just wanted to share my experience for anyone thinking about buying a cavy from a store. So far Kimper is doing great. He's growing every other minute it seems. He's happy and healthy, but it seems that I might have just been lucky to get a healthy one.
