About Calc.pet

Calc.pet started from a simple observation: dog and cat owners ask the same questions every day — how many calories does my pet need, can my dog eat this, when will my pregnant dog give birth — and reliable answers are scattered, buried in veterinary manuals or in generic calculators with no clear source.

Our goal is to bring those answers together in fast, free, straightforward tools, always citing the scientific or veterinary source behind each formula. You can check all of them on the methodology page.

Calc.pet is an independent project, maintained by a single developer, with no ties to pet food manufacturers, veterinary clinics, or laboratories. When we recommend a product through an affiliate link, it's clearly disclosed.

No calculator on this site replaces a veterinary consultation. If your pet has an emergency, seek professional care immediately.
