I use an entire bag of orzo (500 g), 4 cups (1
liter) of water, and put a
box / can of tomato product (usually thick sauce like pummaro, but diced
if I'm out), and double everything else (cheeses, herbs, zest, etc.), and bake it for the same amount of time in a large circular aluminum pan.
The vet suggested that I empty a
liter box for the cat to pee, but he just won't go into that empty
box to pee... I wonder
if blood test would work too... also, I feed thim grain free canned food (mixed with 2 tablespoons of water) and I also give him some boiled chicken breast as a snack.
