Changed my bedding for my rats heath... URI better for it?

[~*~Perfection~*~]

My rat Nutmeg, Has a sevre URI. She was given Batril tablets but it is mostl ikely it isn't going to work, and that her chance of life is slim. This is her second.
They were on carefresh and considering it's really dusty for rats, i am changing to Yesterdays news.
I am hoping this will help her URI more. I also got baby food for her (To weak to eat) and i put the tablets in tomorrow so she will eat it. The flavours i got are :
Apple Rasberry, Strawberry, Mixed Veggies, and apple blueberrie.
So far she has only tried the strawberry. She has gotten realy clingy and I am super sad I dont know if she'll make it.

She is actualy eating, but she's sleeping alot.  I dont know if she can pull through. It'll be 2 ratties so close, lost one, I dont want to lose another.
