So we got a guinea pig a couple months ago and its 4 years old. We got Pudgy from a family that listed him on craigslist becuase they were moving. Well he's very grouchy and always chatters his teeth when I try to catch him to play with him and he hates laptime. I don't get it, we give him veggies everyday and spot clean everyday but he's just grouchy all the time. We used to have 3 other guineas like a year ago and they were very happy and nice and would come up to us if we went to the cage. We also gave Pudgy a cage 8 times the old one he had. He popcorns sometimes but doesn't like us touching him or anything. I have a picture of his cage in my gallery.
