One of our cats is now diabetic. Fantastic. I feel bad for him, but this is going to be a logistical nightmare. Merry and Sam both think they need the same food (they both suffer from your-food-is-obviously-tastier-than-mine-and-I-must-therefore-eat-yours-before-you-do-itis). When Merry was the only one with a special diet, we took the easy route and just fed all 3 kitties the "Merry kibbles," but now we have competing health issues requiring very different diets. We'll get to a balance point eventually, but for now we're all a bit testy about the situation.
