3 month old Fudge constantly squeaks, in fact the only time he shuts up is when he's eating or sleeping (my OH says just like his mummy ;D). How normal is it to be so vocal? I want to add more piggies near to him and when he's older get him a friend, but I'm beginning to think it'll be so noisy! He does sound very sweet - is he doing it cos he's happy/hungry/pleased to see me/fed up ?
