Thanks the grey boys are one year old brothers, I swear they are twins. I have yet found a marking to tell them apart. I just watch their actions :cheerful: The brown one is about six months.
They are so cute! They look just like my two silver agoutis, here are some pictures of them: https://s211.photobucket.com/albums/bb254/envisionary333/My%20Piggies/, https://s211.photobucket.com/albums/bb254/envisionary333/My%20Piggies/?action=view&current=MayaRoxyPearl.jpg. They have different markings so I can tell them apart, though.
Don't you have problems with the piggies chewing up the basket?
Do they eat it? I don't think that's safe for them. You might want to get them a "grassy hutch" instead, it's a hidey house that is safe to eat.
i buy all natural baskets so they are perfectly safe thanks though! besides once they shred them most of the pieces get removed with the litter change!
