How can I effectively train my cats to stop pooping on the floor?

To effectively train your cats to stop pooping on the floor, you can start by ensuring they have a clean litter box in a quiet and accessible location. Use positive reinforcement, such as treats or praise, when they use the litter box correctly. Clean up accidents promptly and consider consulting a veterinarian to rule out any medical issues. Consistency and patience are key in training your cats to use the litter box.
