Here we are really talking of diabetes mellitus – sugar diabetes (the other kind of diabetes – insipidus is rare)
Another disease we see more and more of – rather like the increase being observed in humans.
Aggravated by obesity, diabetes is best avoided so watch your pets weight.
Your pet will almost certainly drink more and eventually lose weight. If you are concerned bring your pet in. A very quick blood test will tell us all. Treatment may involve diet change but usually by the time we get to treat diabetes insulin injections will be required. Have no fear! Injecting is much easier than you think and the needles are very tiny.
