Thanks everyone! Guess who peed a great big pee over her litterbox as I was getting her carrier? Sigh. Rescheduled vet for tomorrow, no apt left today.
Lyane, Willow is getting a mixture of foods because (1)we're trying to avoid chicken and (2)she needs pate, combine these with (3)low carb and (4)low phosphorus, and it's difficult. Also, she goes through extreeeeeeemly fussy phases when she's nauseas, which ups the fun factor. We also use purebites toppers to keep her motivated, and as reward treats.
We avoid the pate issue by making a slurry with water with the immersion blender.
She gets a mixture of Merrick limited ingredient turkey (which she loves), Weruva Meow Luao (I spelled that wrong lol) and Weruva truluxe glam n punk, which is ideal
but she'll only eat it alone for a while. Some of these are higher phos than I like, but I hope the others bring the level down....wayne has a ratio of the three he feeds. Carbs on all 3 are fine.
We also fed Instinct limited ingredient turkey, I can't remember why we stopped that...now I have to look at it again.
Whole Earth Farms duck pate changed their formula and is now high phos.
If your girl can eat chicken there are quite a few weruva that are low phos I think, like fowl ball and frickazee if I remember correctly. (The Weruvas tend to be lower calorie though, so you need to feed more, and Willow can't/won't eat larger amounts of food).
I suspect that I'm going to have to add a phosphorus binder after this bloodwork because her phosphorus was creeping up last check, and her calcium was a bit high.
Hope this helps some, I'm sorry your girl was diagnosed with crf, it sucks

We also do SQ fluids when constipated/off food or water. I can let you know where we order supplies and meds if you'd like.
With love, Nikki
