How It Works

Estimates costs across: first year (setup/spay-neuter/initial vet), annual recurring (food, routine vet, supplies, insurance), and lifetime projection (expected lifespan for dogs and cats). Includes emergency medical contingency.

  2. Cat (18-year lifespan): First year: $1,800. Annual: $1,100. Lifetime: ~$20,000.
Result: Dog lifetime cost: ~$28,000 ($155/month average). Cat lifetime cost: ~$20,000 ($93/month average). These costs vary significantly by breed, health, and geography (veterinary costs are higher in urban areas).
