Weird blood values in my cat (bile 95 vs 13 )

Hi, I have a question about my cat Rover hes 1 year old and neutered. A while ago he was having some problems with his blatter being ( mind my english ) full/unable to unload, he was catheterized and after that it looked okay again. Day after he was unable to unload again and we choose for surgery in where his penis/etc was removed so couldn't get obstructed anymore. The Vet send the stones they found to the US for research and it came back as being Urate stone, something very uncommon for a cat of this age. We also let the vet do some blood work and that came back positive mostly. It seems Rover has a very high bile value -> don't know the specifics but the rate they told me was 95 in where +/-13 is a normal one. Since my own vet and the academic study center can't really give me a final answer they suggested it could be a liver shunt and that he would need more tests. The problem is that he only has the high gal count and for the rest is very healthy, recovered very quickly and is one happy cat again. We feed him raw since we got him and now just dilute his food more so he pees more. Since we know it's Urate i also add more muscle meat to lower the purine protein count. He is happy, active and feeling good. Peeing like a boss and shows no sign of being unhealthy. The biggest problem is that they can't give a full answer because they don't know / haven't been many studies about bile for cats and/or it is harmfull for having such a high value. Only thing for sure it is not normal.
