I had one of my kitties spayed a week and a half ago, and the incision was closed like a belly button rather than like a football's stitching. If that makes sense... A week and a half later the stiches are out (they're the kinds that dissolve naturally), and she has what looks like a human outie belly button (size and shape, too). I worked up the nerve to touch it, and it's really hard on the inside, like it's packed solid. Is that normal? I had another cat spayed by the same vet with the same type of stitching, and no outie. Should I be worried? Will it go away naturally? What's in there? Hmmm....
