Hi, Our 5 year old cat Buddy was diagnosed yesterday as having Diabetes. Not knowing anything about feline diabetes I was happy the vet was going to tell us what to do.. Buddy's glucose reading was 480. The vet gave him 4 units of Prozinc which I now know was a high dose. He sent us home with insulin, syringes, weight management canned cat food and told us to feed him that until we order the prescription purina D/M cat food (which I now know is not the best and should be avoided). He told us to start giving him the 4 units of insulin every 12 hours.. suggested 6 or 7 morning and evening which would be the best times for us but since he didn't get his first one until 10am ..that with readings that high I should give him another at 6 or 7 pm last night that it would be ok.. that didn't happen. He hasn't had one since and I'll explain why.. My husband is diabetic. He has an Accu check meter. After reading how to check your cat's glucose I did it with his meter. At 4:13 pm with my husband's meter the reading was 114. At 6:57pm the reading was 80. At that time I was afraid to give him any insulin.. I especially wasn't going to give the 4 units the vet said. I'm actually very upset thinking that if I did not know the dangers (thank God I looked into it) my Buddy could have died!.. At 10:30 (or 10:50 I can't read my own writing) the reading was 81. Buddy sleeps by my head so I was able to know how he was during the night.. I'd wake up and pet him, talk to him and just let myself know that Bud was ok.. Before I go on I will talk about the food.. Bud use to eat meow mix freely.. I have 3 cats and of the 3 Bud got the fattest.. over 19 lbs. I began to notice he wasn't able to jump into the window any more. He was drinking more and eating all the time. I decided he needed to go on a diet. I started removing his food at night completely and only giving it a couple of times a day for an hour or so. He started losing weight and very easily. So fast that I was sort of concerned and over time stopped removing the food. By this time I noticed the litter wasn't going as far.. I was scooping much more often and it was harder to scoop. I realized the urine was like concrete. I had to figure out which cat was doing this and realized it was Bud..so the vet trip and the diagnosis.. He weighed 16.6 at the vets.. Now back to the food. He didn't like the weight management food.. I had took away the meow mix from him.. and when the reading at 6:57 pm was 80 I was concerned after the huge dose of insulin. I could picture it going too low so I got my husband to go to the nearby store and pick up some other canned cat food. He ate it a little better. But I was still concerned so I must admit I put the meow mix back down for a bit.. I don't think he ate much of it. The reading this morning was 57. He seems ok.. I certainly didn't give him any insulin.. I was thinking if the readings were up I'd give one unit or so but nope, couldn't do it.. I fed him some canned food and I'm watching him.. he's laying around and looks ok. Not sure what to do .. I'm thinking of going to walmart today to get a relion meter. Not sure what else to do at this point..Thank you for your time. So sorry this is a jumbled mess. I have a lot to do today but wanted to get this posted.
