My cat isn't standing after spay, peeing a lot. Should I call vet?

Hi and thanks for using Petco Pet Education Center, formerly Petcoach! Sorry to hear that Zoll is having a prolonged recovery. Don't feel hesitant to call the emergency number that the clinic provided. If she was more awake I would advise that you try to get her to eat a small bit of food. That will often help them recover but don't try it unless she can hold her head up. One thing you can do is take some sweet liquid such as honey or sugar water and rub it on her gums and tongue without getting bit though. That may help her recover faster. Also get her warmed up. She might be cold and not recovering due to lower body temperature. Use care but warm her up somehow with warm dry towels or something else. Just use care and don't burn her. It is possible she has some kidney or liver problems and that the drugs are not being metabolized properly. The reversal agent (I'm assuming what that is) usually works faster in normal patients. Again I would call the emergency number. She may need more reversal agent or fluid therapy to speed up recovery. She is probably urinating because of the anesthetic drugs she was given. I'm sorry you are having a tough time with her. I hope you can contact somebody.
