I had my kitten spayed and she had the normal lump/swelling from internal stiches. But, after it all went away she still has a good-sized fat pocket on her tummy. The vet tech said sometimes when they get spayed fat seeps out and gets trapped. She said it will never go away but shouldn't bother her. Is this true, or did they mess up? It doesn't look right - she is a healthy kitten with a pooch hanging down from her tummy! I've never heard of this happening. Anyone else??
