Lonecat,
I'm so pleased that you are a vet, and a very good one I'm sure , but I have to comment on a couple of things you have said from my personal experiences.
When my cat was diagnosed as diabetic 5 years ago, he was very unwell and the vet pushed us towards euthanasia, suggesting he would not improve and have no quality of life. I did not agree with this and cat is still leading a healthy life on bd insulin. The vet wanted to put him to sleep, not the owner.
Home testing of diabetic pets ( cats and dogs) is not a step too far. Its easy to learn, painless for the animal and relatively inexpensive. The reason most owners in the UK do not home test is either that it is not suggested or they are put off by their vets and staff who have little or no experience of it. I watched my current and past vets fumbling to get samples from my animals ears and was shocked. Its much easier to test on the inner lip or carpel pad. Have a look at the amazing K9 diabetes website and you tube for more info. I have since then taught my wonderful vet and his staff and other owners to home test and they manage fine and love the lack of distress to their pets and valuable information it gives.
Fructosamine testing is really not that useful IMO as it only shown average readings over the last 4-6 weeks, It completely misses highs and lows and these are what give rise to problems in animal diabetes. For example a dog could be having lows of 3 and highs of 20 and the fructosamine may show "good control" .
As a human nurse I know we would never start a patient on insulin and not start home blood testing. Its far too dangerous. Its not a step too far for parents to learn to test their childrens blood. No one would question this, in fact it would be dangerous not to.
