My cat has been diagnosed with an enlarged kidney. There is a lump on her top right side of the middle of her body. She has been losing weight for the last two years, very gradually. She is now 6lbs and has lost 3 lbs in the last 3 months. I finally took her to another vet and they are saying she has a very large mass on the xray. THey compare her blood work to the last and they do feel she is doing better in that area. She has a small amount of protein and white blood cells in her urine. But nothing to indicate Kidney failure. She also has a small stone in her other kidney. They are checking her urine for bacteria. They are suggesting that she still have the enlarged kidney removed even if it is bacteria in her kidney. They would normally give antibiotics for this. I really did not want to have her undergo such an invasive procedure. The last month I have been changing her diet to a more natural one. She is eating and going to the bathroom normally. Is there anything I can do at this point to help her. I am very distressed over this situation.
