    My cat Rumsey had a serious kidney failure due to a urinary tract infection, which led to the removal of one of his kidneys. He continued for a year on and off with crystals in his urine and frequent uti's. Until we finally got the right rx food and the right rx prescriptions. On top of the one kidney Rumsey has now developed a heart murmur about four years ago diagnosed. With the help of his medicines Amlodipine and clopidogrel. It has now been 6 years since his surgery and near death experience and he is going strong lovey doves sweet heart. Thanks to the medical team at hillside animal hospital Dr Rosonke and chewy.com
