HoHoHo!  Merry Christmas!  Your guinea pig will look the part for you holiday events in this very detailed elaborate guinea pig Santa costume!  Made with a red velvetty type fabric, a nice white fuzzy trim, and a velvetty belt with gold lame buckle.  Great for your family Christmas pictures (you do include your guinea pigs, right?).  

I'm sure you have more than one guinea pig, get two, and one can be Mrs. Claus!
