Who provides PetYardstick

PetYardstick is provided by AdModifier LLC ("we", "us"). Its pages and calculators are free to use. By using them you agree to these terms with AdModifier LLC.

Not veterinary advice

The results are worked out from published veterinary references. They are general starting points for healthy animals, not advice about your own pet. Every animal is different. Before you change your pet’s food or plan around a pregnancy date, check with your vet, and contact a vet at once if your pet seems unwell.

Names of organizations and companies

Names of veterinary organizations, publications and companies appear only to say where a number comes from. PetYardstick is not connected with, or endorsed by, any of them.

As it is

The site and calculators are provided as they are, without any promise that a result suits a particular purpose.

Copying

The text, drawings, examples and code of this site are ours. You may link to any page and quote short parts with a link. Please do not copy or republish whole pages, tools or the design.

Changes

We may update these terms; the version on this page is the current one. Questions: hello@petyardstick.com
