My heart is breaking . My 4yr old tabby twinkie was diagnosed with kidney failure. She's really weak , drinks lots of water & is still eating which is good. She is the most attached cat out of my bunch. I love her sooo sooo much and the vet said she's very anemic. She has very low protein so thats why he doesnt want me to give her fluids because he said she was just bloat. He said in her case its really bad since shes so young and it only gets worst. I dont know what to do I dont want to put her down till I see her reallly weak where she cant even stand. She still stands but doesnt move just stays in top of my table and thats where she uses the bathroom. If i put a litterbox she will try and eat the litter. It kills me . I never put a cat down to sleep. Im only 20 years and she is one of my first pets. Any suggestions? Help? I dont know when to put her down. ? my heart is broken ;[

Here's my sweetheart ;[
