Drinking and urinating a lot is what you see in most cases. One of the first signs of diabetes is urinating a lot. For example, you can notice that the puddle corner is constantly wet. Hamsters produce about 7 ml of urine a day. A Dwarf Hamster with severe diabetes can urinate up to 75 ml per day. This is also accompanied by large amounts of drinking and you will probably have to refill the drinking water more often. This could be a sign that your dwarf hamster has diabetes. Incidentally, drinking and urinating a lot does not always indicate diabetes, it can also indicate a problem with the kidneys.
