We took our 12 year old kitty Sam to the vet today. I am feel very overwhelmed by the news were given of diabetes. Any advise or tips to make my kitty's life less traumatic then visiting the vet all the time. We purchased our first bottle of insulin today and was told not to change his food until our next appointment in 2 weeks. What foods are recommended once we do change his diet? It's sure been an emotional day at our home. I am feeling guilty that the financial part of his treatment is a concern for me. Have others felt the same way?
