Let me preface by saying I'm an American living in South Korea.  My vet speaks English poorly, so we're having some trouble communicating.  Anyway, my six-month old kitten, Mathilda, was spayed two weeks ago.  At that time, the vet inserted a plastic tube in her abdomen because he said she had a fat pocket and the fat was "melting" and needed to drip out of the tube.  I took her home and kept her isolated in my bedroom because I have another cat in the house.  Every day several drops of fat and blood dripped out of the tube.  I took her in daily for antibiotic shots and gave her meds three times a day.  After a week and a half, he removed the tube because it was causing irritation, even though he felt it should have stayed in longer.  Then he packed the tube hole with gauze because (I think) it's too irritated to close.  So the upshot is that at two weeks after surgery, my cat is still stitched up and the vet says she won't be healed up for another two weeks.  When I asked him why the tube was necessary at all, the vest said that it was a common procedure if the cat was overweight.  I've never heard of such of thing.  Can you help me clear up the point of all this suffering Mathilda's going through?
