Frequently asked questions
What tools does ThePawManual offer?
Are the calculators free to use?
Yes. Every calculator on ThePawManual is free, runs in your browser, and doesn't require an account or email address.
How accurate are the calculators?
They're built on published veterinary models: size-aware aging formulas, the resting-energy formula vets use for feeding, and researched price and breed data, never rules of thumb like "multiply by 7." They give a solid estimate, not a diagnosis; a veterinarian is still the right call for anything health-related.
What tools are coming next?
A pet name generator is next. Each tool ships only once it works, so there are no placeholder tools on the site.

Cat Age Calculator
A cat's first year of life equals about 15 human years, the second year brings the total to 24, and every year after that adds roughly 4 more. That means a 5-year-old cat is closer to 36 in human terms, not 35 (the "multiply by 7" number): close by coincidence at that particular age, but […]

Cat Food Calculator
A 10 lb (4.5 kg) indoor, neutered adult cat needs roughly 180–250 calories a day, and a more active neutered cat of the same size about 260. That's usually less than the feeding guide on the bag suggests. Enter your cat's weight, life stage and lifestyle below, add the calories from your food's label, and […]

Dog Age Calculator
A dog's first year is worth about 15 human years, and the second year adds roughly 9 more: putting a 2-year-old dog at about 24, not 14. After that, the old "multiply by 7" rule doesn't hold up: each additional dog-year adds somewhere between 4 and 5.5 human years depending on breed size, because larger […]

Dog Food Calculator
A healthy, neutered adult dog needs about 1.6 times its resting energy requirement each day: roughly 350 kcal for a 10 lb (4.5 kg) dog, 790 kcal for a 30 lb (14 kg) dog and 1,500 kcal for a 70 lb (32 kg) dog. Puppies need two to three times their resting energy, very active […]

Pet Cost Calculator
In the US, a typical adopted medium-sized dog costs about $750–$1,650 a year in food, routine vet care and supplies, and a cat about $550–$1,350, before insurance, grooming or boarding. The first year costs more because of adoption, spay or neuter, vaccines and setup gear. Choose dollars or euros, describe your pet and your plans, […]
