Nala seems to be drinking plenty of water, and doesn't seem to be dehydrated on the skin-pinch test. She's on to me on the chicken-flavored pill pockets that her Azodryl goes in, and I just bought another package of the chicken, so this afternoon I'll stop by the store and exchange it for beef flavor. Once I get her started, she does eat her meals of chicken/rice/sweet potatoes/ricotta cheese about 1 cup total volumn. Vet checked her teeth, and didn't notice anything of concern.

Her sudden rapid declince is the hardest thing to watch.
