Save Rimba

I have adopted Rimb (my cat) since 6 month a go, she is super active but 1 day I found out that she is not as active as before, she turned to be so pasive, I brought her to the clinic but the doctor suspected her to have imflamation of lungs. The doctors gave medicine, day after day she is getting worst. She did not take any food as she did not smell the food and started not to move until the doctor suggested me to bring to the specialist hospital. But the cost is quite expensive as she need to go under a surgery. I hope you can help me to save Rimba..
