Dog vs Cat: Which Is Cheaper to Own?

Here is a direct annual cost comparison for a typical medium-sized dog vs a typical domestic cat:

| Category | Cat | Dog (medium) | |---|---|---| | Food | $300–$500 | $400–$800 | | Routine vet | $200–$400 | $300–$700 | | Grooming | $100–$300 | $200–$600 | | Insurance | $200–$450 | $400–$900 | | Supplies/misc | $100–$200 | $150–$300 | | Daycare/walking | $0 | $0–$2,400 | | Total | $900–$1,850 | $1,450–$5,700 |

The wide range for dogs reflects the enormous variation between a low-maintenance breed with DIY grooming and no daycare vs a high-maintenance breed in an urban environment with professional grooming and daily dog walking.

Cats are cheaper on average, but several cost areas catch cat owners off guard:

Litter: Ongoing litter cost is often underestimated — $150–$400/year depending on litter type (clumping, silica crystal, biodegradable) and how many cats you have.

Dental disease: Cats are highly prone to dental disease, and dental cleaning under anaesthesia ($200–$600) is recommended every 2–3 years from middle age.

Hidden vet costs: Cats are notorious for hiding illness. By the time a cat shows obvious signs of kidney disease, hyperthyroidism, or dental pain, the condition is often advanced — making treatment more complex and expensive.

Boarding: Cats do not do as well in kennels as dogs. Many cat owners use professional cat sitters at $15–$30/visit — potentially $300–$600 for a two-week holiday.
