Hi background: my cat was diagnosed as diabetic 3 years ago and has been eating dry diabetic food ever since,twice a day - and 3 units of caninsulin twice a day - this has been stable for 2 years - was up and down in the first year. due to what turned out recently to be a sore mouth, different vet at the practice suggested wet diabetic food - which she is loving. she is so much perkier and actively wants to be fed at the normal 2 x mealtimes. I have read on here that the wet is much lower in carbs - so until the test kit arrives I have reduced her to 2 units twice a day. i realise I am guessing but I am thinking better to give slightly less than too much - coupled with the fact she seems so much better and perkier in herself. what I am really wondering is - after reading all the testing you guys on here do - why/how was she maintaining or appearing to be maintaining a level of 5.6 which vet said was near perfect at each test time- and only being tested 3 or 4 times a year by the vet - no home testing ?
