Actually, I think that did happen to me. Cats are perceptive and seem to know that something has happened, and want to check you out.
My wife and I also returned to babsysitting our 3-year-old twin grandchildren the day after I got home, and I survived that, too. They were very good about avoiding Grandpa's "owies," but curious to see the incision.
I think you'll be fine, but watch for any unusual symptoms.
