Callie's twin brother, Patches, has been showing symptoms of diabetes. He has lost about a pound, seems to not be grooming himself and the litterboxes are wetter than in the past. I just took his blood glucose and it was 410 at 2:30 in the afternoon. I can't get him into the vet until Saturday morning. I plan to try to keep him on Fancy Feast till then. If he is diabetic, I want to try a trial of Pate food only before going on insulin. Callie passed away in her sleep about 6 weeks ago and I still have all her supplies and Lantus insulin. For some reason, I haven't been able to give her things away. I knew siblings were more apt to have diabetes. I do have some questions, how often should I test Patches's blood glucose if he isn't getting insulin and how long should I keep him on the food only trial before putting him on insulin?
