How can I successfully manage a multiple cat household?

To successfully manage a multiple cat household, provide each cat with their own space, litter box, and food/water bowls. Regularly clean and maintain these areas to prevent territorial issues. Provide plenty of toys, scratching posts, and vertical space for exercise and mental stimulation. Monitor their behavior and address any conflicts or health issues promptly. Establish a routine for feeding, playtime, and grooming to create a sense of stability and reduce stress.
