I only have two, but wish I could have more! And I agree with all the other Moms, they are the sweetest, gentle, most docile little critters! As for them being smelly, no at all!! I have heard that Ferrets (which I love!) do have a certain odor from a scent gland that is very easily controlled. Perhaps that's what you are thinking of? I recommend piggies 100%! Everyone's piggies are so cute!! Great pics, all!
