Dushka went for her check-up blood test today, and the result is very worrying. Her creatinine is now down from 3.7 to 2.8, and the urea level is 37. The blood glucose is up a bit to 169, though that could be stress. The vet could not suggest anything right now other than what I am doing - Semintra supplement daily and a renal diet. Her athritis is no worse and doesn't seem to be causing her pain when she is manipulated so the glucosamine is working in that direction, at least. If she starts to vomit her food up then they will put her on an infusion to try and restore levels, but for now we must carry on. I can't bear to see her go downhill too - this year I have had too much already. She is 14, my oldest cat, and I have had her since she was 3 weeks old.
