What should I do if my male cat passes red urine?

Male cats passing red urine may be suffering from urinary system diseases such as bladder inflammation, urethritis, and urinary calculi. Generally, they will also exhibit symptoms such as difficulty urinating, poor urine flow, frequent attempts to urinate, and cloudy urine. It is recommended to see a veterinarian promptly.

Secondly, it may also be due to accidental poisoning after consuming chocolate, grapes, or onions, which causes hemolysis in the body, leading to bloody urine. Additionally, cats exhibit mounting behavior during estrus, which can cause genital injuries and bleeding, thus causing bloody urine when urinating.

Urinary system diseases

If your male cat is passing red urine, consider whether they are suffering from urinary system diseases such as bladder inflammation, urethritis, or urinary calculi. Your cat may exhibit frequent visits to the toilet with minimal urine output and blood. If you notice this situation, please take your cat to the pet hospital for examination and treatment. Depending on the cat's condition, they may require biochemical, ultrasound, DR imaging, urinary catheterization, and fluid therapy.

Food poisoning

If a cat accidentally eats spicy or unsuitable foods like chocolate, grapes, or onions, they may become poisoned and exhibit bloody urine. If the owner discovers their cat has eaten these foods and shows symptoms of bloody urine or other adverse conditions such as diarrhea, froth at the mouth, or seizures, they should take the cat to the pet hospital for emergency treatment like gastric lavage to ensure the cat's safety.

Estrus

During estrus, male cats may exhibit anxious behavior, howling at night, urinating randomly, and mounting behaviors. When climbing over rough objects, they can suffer genital injuries and bleeding, causing bloody urine when urinating. If this is the case, owners don't need to worry too much. After the estrus period ends, neutering the cat is the solution. Additionally, after neutering, owners should regularly administer medication to prevent wound infection and inflammation.
