We took our 16 year old cat, Max, in for her check-up last weekend. The results were not good, but they are definitely confusing to us. She has elevated liver enzymes, elevated thyroid levels, elevated kidney enzymes, a slight anemia, protein in her urine, and a mass in her kidney.
She is now five pounds - she has lost a couple of pounds since her last vet visit. She is doing well physically, though - she eats a lot, drinks a normal amount of water, pees and poos normally, and has good energy for a cat her age. One different thing she is doing is meowing a lot, though - every time we go in the kitchen, she goes in there and meows for food.
The vet would like us to do an abdominal ultrasound (for $400); the vet who was examining her did a short ultrasound just to see what was up with her kidney, and she found that at least half of her kidney is just a mass - no normal kidney tissue.
I’m waiting to hear about her urine culture results - they think she either has a bladder infection or protein in her urine because her kidneys are bad. We haven’t heard from them for a week, so I don’t think it’s an infection.
The vet would like to put her on a low-protein diet because of her kidneys, and on a low dose of thyroid medicine for her hyperthyroid levels. The vet also thinks that bringing her thyroid levels down could possibly help her liver enzyme levels, kidney enzyme levels, and anemia. I’m not sure about this - when you put all these things together, it kind of sounds like she isn’t doing too well - her thyroid levels aren’t terribly high (about 67 when the upper limit is 55, I think).
Any ideas? Should we go ahead with the ultrasound to find out the extent of the kidney problem, and if there is any liver involvement? Should we do the low-protein food and thyroid meds? Should we just let her eat whatever she wants, because she doesn’t have that much time left?
