My male cat has recurring blood in urine and cystitis. What to do?

Updated On September 23rd, 2025

Pet's info: Cat | Domestic Shorthair | Male | 2 years and 10 months old | 12.35 lbs

My cat has blood in his urine. The first time was 4 weeks ago, we took him to the vet and he got antibiotics which he completed, the blood in urine started again about 4 days ago, vet told it's cystitis and got a shot antibiotics, methigel and new food. It got better but today I saw he has blood in his urine again. Is this normal, what should I do? He's a male cat 3 years old.

Hi, and thanks for your question. These signs might be compatible with a urinary tract infection/inflammation. Stress related (idiopathic type of inflammation) infection and presence of crystals are the most common causes of it. Other causes must be investigated at this stage. Urine analysis and abdominal radiographs or ultrasound may be needed. These signs must be checked as soon as possible as urinary tract infection can be dangerous in male (especially neutered) cats as it can develop into a urinary tract obstruction/blockage. A clinical examination at your local veterinarian is essential to confirm these clinical suspicions and treat appropriately.
