Is a cat cheaper to own than a dog over their lifetime?

Yes, cats are significantly cheaper over a lifetime. A dog's lifetime costs (12–14 years) average $15,000–$30,000+ depending on size and breed, with large breeds costing more due to food, medication doses, and boarding. A cat's lifetime costs (12–18 years) average $8,000–$15,000. The biggest cost gap is in services: dogs need grooming ($400–$1,200/year for professional cuts), dog walkers ($100–$300/week if needed), and training—all costs that most cats never incur.

Which pet is more expensive to insure—cats or dogs?

Dogs are more expensive to insure: average comprehensive dog insurance is $50–$100/month vs. $25–$45/month for cats. This reflects higher vet utilization rates for dogs (dogs visit vets more frequently and for more serious conditions on average), higher surgical costs (orthopedic issues are common in large breeds), and breed-specific conditions in purebreds. Cats have a reputation for lower veterinary utilization in part because many owners take them less frequently, which can mean less preventive care but also genuinely lower acute illness rates.
