I found this site couple of months ago searching for natural remedies for my 10 years old neutered male cat. He pees with on his urine. Initially he started peeing on my carpets and I notice blood. I took him to the vet expend a lot of money and he continued the same. I have been giving him the ACV. He is not longer peeing out of the litter box and pees at least three times during the day and twice to three times at night, but continues peeing with blood. Please help! Any other natural remedy to cure the blood in the urine?
