I work at my cities municipal shelter and a couple weeks ago a lady brought in a very small three week old guinea pig that she turned into the shelter. I adopted him his name is Pepe, and within a week also found a local shelter and adopted him a friend, who I have named Petey. Petey is the tri-color american and Pepe is a dark brown what looks like might be a coronet according to the rescue and other people i have asked who are familiar with guinea pigs, but we will see when he gets bigger! I haven't had guinea pigs in about ten years and I'm really happy to have them running around again, I'm even happier I got to rescue them.
