Feline urethritis may manifest as frequent and persistent urination and defecation, but only a small amount of urine can be expelled each time, or even none at all. Difficulty urinating, pain, and sometimes screaming may occur. Blood may be present in the urine, and the cat may frequently lick its anus and genitals. Some cats may also experience vomiting, lethargy, and decreased appetite. 
Treatment for feline urethritis:
1. Feline urethritis can be treated with intravenous fluids. If the symptoms are severe, a urinary catheter may be necessary. This is because if a cat with urinary retention cannot urinate in time, it may lead to acute kidney failure.
2. Feline urethritis is essentially a bacterial infection, so anti-infection measures are essential. These usually involve intravenous infusion, anti-inflammatory injections, anti-inflammatory drugs, and urethral flushing to alleviate the symptoms of feline urethritis.
3. If the cat has hematuria accompanied by urethritis, hemostasis should be performed. The specific method should be followed according to the advice of the veterinarian.
