Cattle can, in fact, suffer from diabetes. Most commonly, cattle will contract type two diabetes; type one diabetes is far less likely to be seen in cows (although it is not unheard of). Diabetes in cattle can be caused by cows being overweight, or being fed poor quality feed. If cattle are exhibiting signs of diabetes, they should be examined by a vet. The condition is treatable, like it is in humans, with regular injections of insulin. There is no need to keep a diabetic cow separate from other cows (except perhaps for feed reasons) as diabetes is in no way contagious.
