My cat Bo went to the vet last week and was dx as diabetic, his glucose level was 436. He was put on Prozinc insulin by the vet at 2 units twice a day. He has lost a lot of weight in the last 3 months and drinks water all the time. The vet told me to change his food to a perscription food for diabetic cats--- MD. Bo does not like the food. I have been reading this site for the last week and have now changed his food to wet foods from Binky's chart, but Bo still has not been eating good. Yesterday he seemed really sick so I took him to the vet this morning and the vet said he has ketones. I have researched and know that ketones are not good, but how bad will this be for him. The vet is keeping Bo overnight and giving him fluids, but he said the blood glucose was registering high (I don't know the number). My vet said Bo could probably come home tomorrow but I don't want him to come home to soon. How will I know if it is safe to bring him home? Thanks for any help.
