I have 2 long-haired cats and they both have diabetes. I have them shaved or groomed 2 or 3 times a year. The groomer won't touch them unless they are knocked out completely. I have never had a problem and didn't worry so much since the groomer is in the vet's office. But we did have a cat a few years ago that lost weight suddenly, so we took her to the vet. She was really scared and the vet gave her an injection to calm her so he could examine her. We didn't know she had diabetes. She went into a diabetic coma and died. It was horrible. I would hate myself something happened to them. Any advice? The vet says it is perfectly safe but I still worry.
