The conclusions is: Mir is doing great for an 18-almost-19 year old cat.
Everything in the blood work was smack-dab normal except her blood-urea nitrogen level was very slightly elevated. Basically a creatin (sp?) count which usually indicates kidney issues and not processing protein optimally. Her urine sample came back pretty good however, so they just recommended I find her a good low-protein geriatric-cat diet and get her blood checked again 6-12 months from now to keep an eye on her kidney function.
Finding a new food is going to be VERY annoying because she is sensitive to grains. I hatehatehate Science Diet - she was so greasy and unhealthy when on it before. They didn't think she was near serious enough to warrant any kind of prescription diet though.
I also need to give her daily glucosamine for her maybe-arthritis.
Her teeth looked good - some tartar, but not enough to need a tooth cleaning in such an old gal. No masses or weird lumps. Her nose-cancer looks about the same as it has for 6-7 years, and this vet agreed it's probably one of those non-invasive sarcoid/sarcomas - also not worth worrying about since it isn't itchy and grows SO slowly.
She doesn't have any other signs of kidney issues like weight loss or barfing - I just noticed she seemed to be peeing slightly more, which is why I took her in for blood work. According to the vet if I notice THAT much of a difference (literally it was one tick above "normal") in her habits, then she's in good hands. I know Mir has a small bladder because she has a thickened bladder wall from having like 3 bladder stones removed in her youth, so that was something I factored in too.
So the summary of results: doing SUPER for an elderly kitty, kidneys not bad but I'll need to keep an eye on them, and what is probably a touch of arthritis in her deformed leg/foot.
I'll do some research on the other Wellness diets - maybe the one for urinary-tract health would be good for her. Any recommendations for high-end brands (without corn or wheat for SURE) that have good senior/ancient cat dry food diets? She isn't overweight and only tends to get fat and nasty if she is eating grains so...
I hope she keeps on trucking for many years to come. Ahh kitties!
