My ragdoll cat has an upset tummy, bless her. She has a lot of poo down her fur and I've no idea how to get rid of it. I've never had a long haired cat before, so I'm not quite sure what to do. She occasionally has had this before and we've just sort of snipped it out, but it's really bad this time and she smells quite a bit and I know it's upsetting her. Any ideas???
