Animal calculators: any species ↔ any species
A hamster grows up in weeks, an elephant in years. While everyone multiplies a dog's age by seven, we compare any species with any other — from a beetle to a whale.
- The most accurate age conversion: up to 8 matching life-stage points (birth, childhood, maturity, old age…) and a special formula instead of multiplying by period coefficients like vet-association calculators.
- Any species ↔ any species: hamster → cat, parrot → tortoise, human → capybara. Thousands of pairs, not only “cat and dog”.
- How much would you weigh in a hamster's body, and how many shrimp would your cat eat.
- Unusual reminders: birthdays and anniversaries in the years of other animals — congratulate a friend on a beetle anniversary or celebrate a capybara birthday several times a year.

How it works
We know that an animal's exact birth date is often unknown. That's why the birth-date picker lets you set an approximate range of dates or ages. The finest precision of that range is 15 minutes. We also take time zones into account to work out the birth date as accurately as possible.
Why is it more accurate than “multiply by 7”?
Each pair gets its own curve through the life checkpoints of both species, so a puppy and an old dog are converted differently.
Can I compare any animals?
Yes: pick any two species — a human, a pet or a wild animal — and the calculator converts age, mass or diet.
What are the mass and diet curculators?
They answer funny questions seriously: how much you would weigh as a hamster and how many shrimp a cat needs — using body proportions and metabolism.
