Pottering in the garden, I've come across a couple of almost cat poo like things on the lawn. Only they seem to have a lot of hair in them! Our girl cat is very long haired, could these be coughed up/pooed out hairballs? We do brush her regularly, but shes always grooming herself. I have zero knowledge of hairballs, are they normal? Anything we need to do incase these are hairballs?
