Quick answers, calculated in your browser
These tools work right in your browser: nothing you type is sent or stored. They're based on the same sources as our guides (the AVMA, International Cat Care, the Merck Veterinary Manual and US cost data), and each page explains how the result is calculated.
What each calculator does
- Dog age in human years: by size, because big dogs age faster.
- Cat age in human years: with your cat's life stage.
- Daily food portion: calories and cups of food per day for dogs and cats.
- Yearly cost of a dog: food, vet care, prevention, insurance and extras.
- Can my dog eat…?: look up whether a food is safe, OK in moderation or toxic.
Calculators give estimates. They don't replace advice from your veterinarian, who knows your pet.
