Hi Chris,
The alumina has helped in terms of the stool (its now not as dry and hard, still balls though) and also with the stiffness. The urination and thirst is still present. Although the vets thought she was anywhere from 8 to 18 years old, my feeling is that she is closer to 8 years. I think she probably started having problems (urinating outside the box) and her owners probably got fed-up and threw her out, who knows (she had been a pet for sure, as she was declawed & probably spayed). I am highly suspicious of kidney or bladder stones which are vertually impossible to detect. Confirmation to suport my suspicians would be the dilute urine yet no sufficient renal failure detectible at this point. This keeps leading me to lyc and calc-c. Notably, calc-c according to Boger has spots over the cornea (this cat has a lot of spots in her eyes, which is why the vets feel she may be 18 years old, however her mouth and teeth signify she is much younger). She is more active these days, but still sleeps quite a bit (with not much muscle to her, I would expect the smallest exersion to be somewhat exhausting). She also still feels cold and seeks out heat whereever she can. I'm trying to give her less sub-q fluids because she does find it uncomfortable (the fluids are warmed and drip controlled, the sensation must really bother her). Anyways I'm going to watch her closely this next week and now that she has some appetite, I'll try to get her eating raw and more fats like creme etc.
