I just had my kitty spayed this past Tuesday. She is recovering very well and seems to be in no pain. My only concern is that the area right under her incision sight feels sort of hard, like a knot. It is not swollen, red, or draining fluid. It has been that way since we brought her home, so it's probably nothing. I plan on calling the vet first thing in the morning, but wanted to ask just to ease my mind until then. Does this sound normal? It has been a while since my other cat was spayed so I don't remember. Thanks!
