My Devon rex is sick Please help, I need ideas to get her eating again!?

She is 5 yrs old and had fatty liver disease I spent a lot of time, effort and money to get her fixed and back to normal. She is my baby, my life! 4 days ago she wasn't eating or drinking as much. So I took her to the emerg and they ran blood tests everything came out fine she was just a little dehydrated and was sent home. She still isn't really eating or drinking, I just can't really afford the constant emerg fees(as I'm still paying for last yr). I've tried wet food tripe, kitten milk, canned tuna, canned salmon, and I'm even trying her old food that she loved she is eating a bit more than her now food but I need more.!? Any suggestions PLEASE I love her! and want her to be the happy kitty she was!
