How long does a guinea pig sheds its hair?
Guinea pigs tend to shed year round. This is especially true of the longer hair varieties. If you have a guinea pig, be prepared to get used to some spare hair. There are a couple of things you can do to ease the amount of hair that ends up on your shirt though. You can bathe them with small animal shampoo. My local pet store carries shampoo just for guinea pigs. You can also get a shed brush. Once my piggies got used to it, they loved being brushed.
