My cat Franky is 10 years old. His symptoms are weight loss hair loss especially around the neck and shoulders but also on feet. And inside of legs. Unkempt appearance, he looks like he is wasting away. He appears very weak and listless. His urine protein creatinine ratio is 1.0 so it's a bit high and his urine was the color of coca cola. His urinalysis had blood in the urine and protein loss in the urine. But his blood tests were all normal his X-rays all normal and his ultrasound of the abdomen is normal. He has a history of being blocked and had to be surgically unblocked twice but that was a year ago. The vets are puzzled as to what is wrong with him! He also is doing this very strange behavior, he keeps shaking his feet as if they were wet and he's shaking them off but they aren't wet. And he keeps twitching his tail nonstop. Also it seems that his coat is bothering him because when I pat him he kind of cowers or shys away from my pats. What is happening to my poor kitty?!? Has anyone had a similar situation? I am doing fluids and kidney diet food because of the high UPC but his bun and creatinine were normal though the vet said his kidneys were small. Please help!! All advice welcome !
