2 months before he died, he started having blood on his urine. I brought him to a vet and she requested for a blood test. When the results came out, lots of medicine with vitamins were given including a prescription food. After that, he was fine for a while but after one week, he started releasing blood clots through his urine,(looks like shredded liver). Vet wasn't explain to explain what happened. Can you help me? My mind wouldn't rest until I get the answers.
