My kitten was spayed one week ago, and she has a rather large lump at the site of incision. I was told she may have a small lump immediately after, but is this normal for a week later? She's also been acting very strange -overly affectionate. She's usually full of energy and can't sit still, but for the past week, she cries if she's not in my lap. She has to sleep on me at night and meows if I do not pet her constantly. This all coincides with her being spayed. Any ideas? Help is much appreciated
