Hi I am new here today so forgive me if I am on the wrong thread and if anyone can tell me where I should post that would be really helpful. My lovely Luna (aged 11) has lost around 3kg (6.6lbs)in weight and just been diagnosed with diabetes. She is now only 5.7kgs (12.54 lbs) She was given caninsulin by vet at 2 units, once per day for a week which resulted in her in visibly spiralling down within 30-40 minutes every time and having a fever. Her Nadir with caninsulin was about 7-8 hours after injecting. The vet wanted me to give her another 1 unit at night but I refused due to what I consider to be an adverse reaction. The vet finally agreed with me that it must be the caninsulin causing her to have a fever. We changed her to Lantus 2 days ago. For the record, we are finding the Lantus pen difficult to use (there is no 'feeling' with the very fine needle as it goes through the skin) and you can't actually visibly see if any insulin has been delivered - you have to trust in the pen. Also, it only has a choice of delivering 1 unit or 2 units - no other measures. We are testing BG at home (poor Luna having me and my husband for cat parents lol) . First day she had 1 unit at night, second day (yesterday) she had 2 units in morning and 1 unit at night. BG readings yesterday were 10:36hrs - 455, 13:16hrs - 316, 16:49hrs - 324, 22:34 hrs - 401. We really expected the readings to go down at the 16.49hrs test. This morning she has had 2 units @ 10:22 and her BG was 425. We tested her again at 14:24 and her bg is 363 . These readings seem weird/very high? The vet wants us to give her 2 units in the morning and 2 units at night but I am so scared of overdosing her. We don't really know the best time to test her today now but will probably go for 18:30 hrs - does anyone agree/disagree ? The vet is amazing but unfortunately not very experienced with diabetes in cats and is also leaving to go to Australia on Sunday! Any advice would be really appreciated.
