Just finally heard from the vet about Dinky's bloodwork.
Her liver and thyroid are fine--it's her kidney function that is low and she is also slightly anemic, which can be a side-effect of decreased kidney function. I will get together with Dots early next week to find out exactly how to go about treating Dinky's condition. I found a great website about CRF (chronic renal failure) and have set about educating myself. I am glad I learned how to administer subcutaneous fluids--that is a major part in managing this condition. I guess I'll know more after I talk with Dots. She seemed more concerned with Dink's anemia at the moment.
Dinky herself seems totally unconcerned with anything. I have had a couple days now to adjust to all this. This is the way that Dinky will age and she will probably succumb to kidney failure or a related problem in time. But for right now, she is looking great--her usual bright and active self--so I will roll up my sleeves and see what I can do to support her. Older cats are prone to hyperthyroidism, diabetes or kidney failure, so I need to know how to treat this condition. Assuredly Dinky is not the last cat we have who will face this problem.
