The following methods can be used for cats to urinate indiscriminately:

1. Urinary system problems: If blood in the urine occurs, you need to go to the pet hospital immediately for examination and treatment.

2. Bad habits: If it is because of bad habits, you need to scold the cat immediately when it urinates and put it in the litter box.

3. Estrus: If it is estrus, you can take the cat for breeding or undergo sterilization.

4. Place multiple cat litter boxes: You can place multiple cat litter boxes in the room and use different cat litter.

5. Odor stimulation: You can spray alcohol on the spot where the cat urinates, or place a few orange peels to prevent the cat from peeing.
