About two months ago, my cat's behavior changed. She is now about 8 years old. After doing some on-line research, I took her to the vet. They confirmed my fear. On that day, I climbed on a roller-coaster. The vet took extra time with me to explain what was happening to my cat's body; why she was using the litter box more often, which caused her to drink more water. What I remember thinking at the time was, "Boy, I sure don't want this." I also thought of all my friends who live with diabetes every day.
