About Paw Maths

Paw Maths is a small, independent website of free calculators for dog and cat owners, made in England.

Pet food bags give a vague feeding range, “dog years” are usually worked out wrong, and the true cost of a pet is easy to underestimate. These calculators give clear answers in a few taps, using the same methods vets use.

Everything here is free, needs no sign-up, and works on your phone.

A guide, not a vet

The results are good starting points, but every pet is an individual. Always follow your vet’s advice, especially for puppies, kittens, older pets and pets with health conditions.
