Shalom Lynn: The glucose levels for a ferret after a 4-6 hour fast + 85-150 (non fasting up to 207. This is via a blood test. I have no idea if a urine test would come out the same. Any vets out there know??? Feed a good quality of kitten food (better yet ferret food) with a minimum of 30% protein. It is said that ferrets over 4 can use a good quality cat food, but I don't know.... ( Any comments on this, guys???) As for weight loss, maybe give him a few veggies that he likes (mine like cucumbers and red sweet peppers) and cut down on the ferret food, but at that age, be careful. I would consider talking to a good ferret vet before taking any action. There are so many things that can cause problems. Self diagnosis and advice from people long distance can be fatal to your ferret. So, please don't take chances with your fuzzy's life! Hope this helps.
