Hey Kitten,
I too hope your doctor can help you. I'm so sorry for what you're going through.



And i hope this is just a passing relapse with your cat. I can't help thinking if she improved once, she can improve again. The weight loss is normal if she does not eat, or does not eat enough. She absolutely must eat.
All i can suggest is
- try different foods and see if you can entice her: eg if you can find jarred, pureed baby foods that contain meat only, or, make a tuna mousse in the blender, or the (most time consuming), boil chicken and blend that.
- if she abjectly refuses all forms of food, try seeing if she'll lap up diluted wet food.
- failing that, i know this sucks, but i'd forcefeed. she has to eat.
Also you need to ensure she gets enough liquids, and with the scarce eating, that her electrolytes are replenished. there is a fluid replacement liquid you can use which will replace her electrolytes. i don't remember the name, but Bizi used it when her cat was sick...
(
Bizi do you remember what that stuff was? i think humans use it too....???)

p.s. is she exhibiting any
changes in behavior ... esp,
hiding? does she play? if not ... try getting her to play. nothing strenuous, something she can do sitting or lying: bat-the-feather, grab the string... that sort of thing. these are hunter-activities. feed after play, not before.
