Greetings from Seattle! My cat, Boo was diagnosed with diabetes in September 2012. Before that, she was overweight until about two years ago when I put her on a raw food diet (Rad Cat and Primal). Despite that, she still became diabetic (most likely genetic). She experienced ketoacidosis and spent three nights in the hospital. SInce then, she has been on Purina DM and is now up to 4 units of Lantus Glargine twice a day. Still to date, her numbers are running a bit high and not quite yet regulated. Here's the issue, about every two weeks, she gets quite sick (i.e. vomitting, diarrhea, and doesn't want to eat more than a 1/4-1/2 a can - she usually eats a full can twice a day) she also urinates outside the box. This sickness lasts a couple of days but with some Pepcid she gets better and back to normal. I've even taken her to the vet and there's no ketones or anything of concern. After the sickness subsides though, she still tends to urinate outside her litterbox once a day (the rest of the time inside the box). The vet has raised concern that it might be IBS, but since it's very sporadic, she's not sure. Anyway, I'm getting annoyed and I truly believe it might be her diet and possible IBS flair ups. I've addressed changing her back to raw, but the vet is opposed to it until her insulin is regulated. I figured it might be better to do it now as there would be a less likely chance of her becoming hypoglycemic since she's not at the optimal dose yet. I don't know. I like my doctor, but I feel they are so robotically programmed to only recommend the prescription foods that I don't know whether it's right or wrong. Despite the diabetes, Boo was very happy, healthy and energetic on the raw food. Anyone have any experience with these symptoms and issues or changing foods mid-treatment? I'm sifting through the archives, but there's so much information. I thought I might get some more up-to-date responses here. Thanks for your help! Ryan Oh, and for the record, I now have an AlphaTRAK 2 at home to do testing. Though Boo does not make it easy to test.
