Why it pays to do the maths
The old rule “one dog year equals seven human years” has long been outdated, and the feeding guide on the bag rarely fits your pet exactly.
Our calculators take size, age, activity and food type into account and give you an honest orientation you can discuss with your vet.
Frequently asked questions
Are the calculators really free?
Yes, 100 %. No sign-up and no hidden costs, just like our coupons.
How accurate are the results?
They give you a solid orientation based on recognised formulas. Every animal is individual, so discuss important decisions such as a change of food with your vet.
Where do the formulas come from?
The age tables are based on the AVMA, food needs on the RER formula. The breed quizzes use breed traits we collected from recognised sources.
Can I save or share my result?
In the cat breed quiz you get a link to your result that you can save or share. For the calculators, a screenshot is the easiest way.
