Danish stand-up comedian Nikolaj Wulff ( shared this photo of his pet guinea pig getting REALLY excited about finding a piece of carrot. I have the same expression when I run across a slice of cake. Carrot cake, of course. Via I Can Has Cheezburger?
The fun thing about having pets is spending time interacting with them. It& not fun for them or you if all they do is sit in a hutch or cage all day, waiting for their next meal. Of course, you should always have two or more guinea pigs, as they.
