So our poor 13 yo girl has been for her MOT today and turns out she's diabetic. I brought the check forwards a couple of weeks as she's suddenly started drinking a lot more. Not a complete surprise as she had triaditis last year and her pancreas is damaged. The specialist vet did warn us she may do.
Got an appointment tomorrow to go through how to do the insulin injections etc. Feel sorry for her as she's had a rough year.
