I posted a few week ago about my male cat peeing blood. It was a UTI. We took him to the vet, they said his bladder was solid, and they gave him a catheter, and held him for a few days. When he was released, they said he was peeing on his own, and to give him penicillin antibiotic for 2 weeks to get rid of the UTI> He has been acting better, but over the past few days, where he sits, its bloddy liquid, and now brown. He is always soaked in it. I came into the living room this morning and there was that brown liquid drops up my wall, on my computer, everywhere! Some of it was 3-4 feet up the wall! What is going on?! Why is he spraying all over the house, and whats this brown stuff??? It went everywhere. It has been a week since he got back from the vet. Thanks.
