I took my 12 year old cat in for a dental cleaning, she had her cleaning done, once she was getting recover for her anesthesia her heart stop. I was called once that happened, they asked if I wanted them to continue with her CPR. I said yes, they got her back to use. She needed surgery to fix the problem. That same day the surgery was done. She had to stay one night. And I am very happy that both doctor and staff help our baby . She's home with use doing very well .
