On the 4th of April I had a three year old female spayed and because of a larger incision, was in late pregnancy, I kept her in the recovery crate until April 7th and then released her. This morning she showed up to feed and to my surprise, she is acting as if she is in heat and she has 3 males trying to mount her. So, I'm freaking out because I don't want her hurt, incision ripping open, and I didn't think that after being spayed she would go in heat. Does anyone know what's going on? Should I be worried?
