How can I deter my cat from peeing on the carpet?

To deter your cat from peeing on the carpet, try providing a clean litter box, keeping the litter box in a quiet and accessible location, cleaning up accidents promptly with an enzymatic cleaner, and consulting with a veterinarian to rule out any medical issues. Additionally, consider using pheromone sprays or deterrents, providing enough mental and physical stimulation for your cat, and ensuring a consistent routine for feeding and litter box maintenance.
