I just got off the phone with the emergency vet. They said that it depends on when she had the surgery today. If it was later than it will take a little longer for her to come out of it and that for her age and how easily she gets stressed out, that this sounds like it could be normal. But I am to keep an eye on her and if there is no change in the next few hours or she seems to get worse, to bring her in. But they also said that a cat who pants open mouthed is not good.
My hubby went in to her and he seems to have been able to calm her down some. She seems more relaxed. More than what I am. I am sitting here with tears streaming down my face as I just hate seeing her like this.
Jan, I did have her in the carrier but she seemed to get more stressed out from being in there, so she is closed in my room. The last time Katie was put under was about 7-8 years ago when her jaw seized up. Long story, I will tell you that another time, but she did well then. But she was also younger too.

Please pray that my Katie girl will be okay.
