What is the reasoning: Cats are better pets than dogs for people seeking low-maintenance, adaptable companions. Pet care studies show that cats require only 20 to 30 minutes of daily play, self-groom for up to half their waking hours, use indoor litter boxes, and cost significantly less in annual care than medium-to-large dogs, which demand 1 to 2 hours of daily outdoor exercise. Because cats manage their own hygiene, eliminate waste indoors, and require less dedicated exercise time, they fit much more seamlessly into busy schedules, tight budgets, and smaller living spaces. Therefore, their independence and cost-effectiveness make them the superior choice for modern lifestyles.
