Louie is currently under the care of the Feline Diabetes Remission Clinic at the Royal Veterinary College in London, they are recognised as one of the leading expert centres in feline diabetes in the world. Here's what they did when I took Louie to see them 1 week after diagnosis Dec 7th.
1) took him off dry food and put him on Purina DM wet food. Dry food is banned.
2) changed his insulin type
3) did every blood test he needs
4) showed me how to use a glucometer and test him
5) advised me to start filling in the spreadsheet on this message board
6) told me it was imperative for me to test at home
7) showed me how to plot his curve using their free cellphone app
since then he has been diagnosed with acromegaly but that was something they picked up straight away and tested for because of their suspicions (further proof they absolutely know what they are doing). He is going for a CT scan on 5th January to look at his tumour with a view to having it removed. They have said they DO NOT need to do bloods again because the bloods they have are perfectly adequate. I have shared my spreadsheet with the vet who is looking after him at the RVC and also his curves. She emails me with advice regarding numbers, curves and any changes in insulin. She is requesting I do my own testing as and when I feel necessary but to plot a curve at least once a week. She does not need to see me, in fact she's gone to Slovakia for Christmas and New Year so is advising me from their. If it wasn't for the acromegaly I would not necessarily need to see her at all.
What I'm trying to say is that is how one of the worlds leading experts on feline diabetes sees how the standard treatment and testing should be. I would seriously think about changing you vets, either they are not confident enough in their abilities to treat Skinny or they are after your money.
