My kitty was diagnosed two weeks ago and I took her in for her second BG test (her first was before she was on insulin). Her first BG test was at 327. The Vet put her on 1 unit of ProZinc, but when I took her in today her BG was 482. I've changed Mei Li's diet to low carb canned food twice a day so her BG should be going down. My vet says everything is fine and the raise is normal and is insisting she stay on the Purina DM kibble. I know the rise is bad because my mom has diabetes and if her blood sugar was that high I'd be rushing her to the doctor, but my Vet is acting like everything is ok. She won't even really talk to me about BG testing at home accept to say don't do it, and never even warned me about the possibility of hypoglycemia much less what to watch for or how to treat it. So needless to say my Vet is useless and is just draining my bank instead of helping my cat and I don't know what to believe from her or not. Does anyone know if the spike in BG is normal or what might be causing it, and if there's other insulin that works like ProZinc that isn't as expensive (it's $120 for 40 units), and if there's a good vet in Aurora, CO that knows how to treat this better then mine.
