took are one year old cat in to see the vet because he could not urinate. On exame the vet drew fluid and did a ultrasound. There was blood in the urine and the ultrasound showed some indications of foreign bodies but not crystals. She gave us Clavamox a antibiotic, prazosin for inflammation and Buprenorphine for pain all was ok for two weeks then are cat Leo was back in trouble again with not urinating . Same m.o. , and she told us about the PU surgery, or leaving him there for a few days while they but a catheter in him to reestablish his bladder function. My question is this, we feed are cat raw food that we make from chicken livers and hearts with bone ground up for fiber . Leo drinks lots of water so we are wondering why this is recurring in such a young male cat that is a outdoor cat . Is there something we are missing in Leos care or prevention of this problem . love your videos on youtube and saw the cat being unblocked with a catheter, wish we could do that at home.
