of my four cats are (mostly) raw-fed. My vet knows about this, and finds their recent blood test results unremarkable, despite the fact that some of their values are technically "out of range" or near the extreme end of what is statistically "normal". I'm not worried if my vet isn't, but where's the data on this? Does it even exist? Do I need to perhaps compare my cats' results to those of small wildcats, and if so, where's
Mind you, this is all just being asked on the basis of my pervasive obsession with all things feline-related. I'm not a vet or an aspiring one, and I know you are not my vet.
But as for the specifics of why I'm curious...all 3 of my younger kitties (feral-born mutt-cat littermates; they'll be turning three years old next month) have creatinine levels of 2.1 - 2.4 mg/dL, and BUN levels of around 32. Judging from a cursory read of info around the web, you'd suspect these numbers to mean HOLY KIDNEYS, BATMAN! Moreover, the younger cats' creatinine and BUN are a bit *higher* than those of my 10-year-old Siamese
...who was just flagged for early-stage renal insufficiency because her urine tested as exhibiting abnormally low specific gravity.
BUT, here's where it gets interesting: my vet seems perfectly happy to attribute the younger cats' results to their very high-protein/practically-zero-carb diet, and isn't at all worried. The younger cats have normal specific gravity, which is apparently indicative of good kidney function as they're properly concentrating urine and their other results look great.
Again, if the Dr. is cool with things, so am I -- her response to my older cat's results seem a strong indication that she knows her stuff.
But I'm still really curious as to whether there are any actual, reliable data out there showing typical lab values for kitties who are NOT on a standard commercial diet.
All I find when I search are (a) "holistic" health sites and message board posts (which are not even close to the level of credibility I'm after) and (b) papers published by large pet-food companies who, for completely understandable reasons, aren't apt to conduct large-scale studies of foods other than those they themselves produce.
I'd been figuring zoos, etc., would probably have this information available online somewhere, but I've not found anything useful yet. Is all this stuff just buried behind a paywall somewhere or am I missing the obvious? Thanks!
