Some cat has been peeing blood. There were suspiciously dark spots on the floor and wall that suggest a male cat is spraying bloody urine. I dampened a cloth to wipe it up and could smell the metallic odour of blood. Now, what to do? The young cats aren’t even a year old yet. Could they be getting kidney gravel? And if so, which one is it? Blockage of the tiny ureter in male cats is a serious problem. Is there any choice but to hie them both off to the vet for tests?
