Every calculator, to scale.
Growth, food and weight, pregnancy and heat, age, and the honest cost of a pet. Each one shows its range, its sources and the date they were checked — and nothing you type leaves your browser.
The calculators are being built. Each one appears here as soon as it is ready.
What the calculators do, and what they don’t
Every calculator is free, needs no account and runs in your browser: the weights, ages and dates you type are not sent to this site, not stored on it and never put in the page address. A link such as “Turn these calories into cups” carries them to the next calculator through your browser’s session storage, and that page deletes them once it has read them.
Each one works from published veterinary sources and openly licensed data, shows a range with every answer, dates its sources and says “Not modeled” where no source exists instead of guessing. The arithmetic is covered by automated tests.
The calculators give estimates, not a diagnosis or a plan: your vet examines your pet and decides. The guides explain the rules behind each one.
