Thank you. I've just left them to it. They have a huge tunnel and a hidey house but if thats what they want, who am I to stop them. They are training me well. I don't mind as long as they aren't eating the vetbed...
Thank you for getting back to me. I'm getting to the end of my teather with worrying. I think I'm just over worrying because I'm new to looking after guinea pigs and over thinking things!
But now I think they have mites!
