Whats up with the wiggle?

Question
When my guinea pig is having some floor time roaming around the house, he will often stop and while keeping both front feet on the floor, lifts each back foot while rocking his bottom back and forth, foot to foot, back and forth.

SO what's that all about? Thanks.

Answer
John,
This could be popcorning! I don't know if this is how they do it, but I have heard of pop corning guinea pigs.

they do this when they are happy, so i have heard!

Don't worry about it though, if it is pop corning it is perfectly natural!

enjoy a long happy life with you little buddy!!
