My 7 yr old kitty, Loki has had tough month. Had a UTI, a week later a random fever, then they discovered a heart murmur. They did further testing and the results indicated kidney disease and cardiac disease. Next Thursday they are retesting his urine and blood to confirm kidney disease or if he has another UTI. I'm waiting on an appointment for a feline cardiac specialist to run tests - EKG, etc to find out more about his heart. At $1k now plus the upcoming appts will be $1k more.
