I feel good knowing that I care enough to even have been suspicious of diabetes. Some other owners may have not even have thought there was an issue. He seems very healthy and happy regardless. I am very confident that we are doing everything we can to keep him comfortable. I really doubt there is anything a vetrinarian can do but I will call and see what they say.
Yes, you do sound like a caring pet owner but you need to take the next step & get proper treatment for the little guy.
He may seem happy & healthy now, but if he has ketones he is heading to serious trouble. Remember, small pets like hamsters hide their illnesses until they become very sick. Because it is almost impossible to place iv's and treat life-threatening emergencies in dwarf hamsters, it is better to have him treated while he is relatively stable.
A diagnosis of diabetes requires confirmation of both high blood sugar & high urine sugar. But the presence of high urine sugar & ketones in a species that is highly prone to diabetes, makes the diagnosis very likely.
Diet can play a role in treatment (pellet only is recommended) but your little guy needs insulin. Now! Some vets may not know how to treat diabetes in dwarf hamsters but if you find a vet with interest in exotics or a least a vet who knows who to a call, a proper treatment plan can be made.
The diagnosis & treatment should not be that expensive in a stable patient. However, by waiting until the weekend, you will likely need to go to an emergency clinic which costs more. But you need to go, today!!
Good luck to him!
PS I find it curious that people don't trust their vets but are willing to trust the nonsense they find on the internet!
