She was drinking more for the past few weeks and they took blood today. She had a very high glucose count at 400. She's always been a tiny cat weighing 7-8 pounds. They gave us a special food and we're going back in 3 weeks for another reading. If the dieting doesn't work, any idea what the cost of insulin is? She'll need 2 shots a day. I'm home in almost all of my free time so I can dedicate the time to her. I'm just not sure on the insulin cost.
