Psycho died about twelve hours later. I had her to the vet when they opened at 8 am and she died around 1:30. She was dehydrated and they gave her an IV. When her blood work came back her potassium levels were triple and her glucose was over 700.
Psycho, as her name implies, was a very difficult cat to handle and treatment has been difficult for the ten years I had her. Almost impossible to get a steroid pill in her (which she was on for the stomatitis which kept her with almost permanent inflamed gums) and antibiotic shots every 2-3 weeks. When she stopped eating the blood sugar just skyrocketed and the vomiting and dehydration just had her system fail. My vet says her heart failed. I was with her when she died, but don't think she was aware as she did purr all night as I stayed up with her and every time I touched her she purred. I just hope she knew I was there. I can not believe how quickly the situation came on and how she went downhill. I have had several diabetic cats over the years and never saw one decline so quickly.
