Symptoms of urethral hyperplasia in cats:

1. Difficulty urinating. General symptoms include screaming when urinating and frequent urination.

2. Poor energy and appetite, vomiting, and not eating much.

3. Bladder enlargement.

Causes of cat urethral hyperplasia:

1. Long-term urethral infection in cats does not receive timely targeted treatment, and severe inflammatory reaction stimulates cat urethral hyperplasia.

2. Because urethral stones are not surgically removed in time, the urethral mucosa at the stone site is stimulated for a long time, leading to urethral hyperplasia in cats.

3. Long-term urethritis and urethral emboli stimulate the urethra and can also lead to urethral hyperplasia.

4. It may also be due to abnormal glomerular filtration, allowing macromolecular substances to enter the ureter and reach the urethra, resulting in urethral hyperplasia.
