Our science

We are nutritionists first. Nutrition is a science.

Every Keos formula starts with a nutrient profile, not a marketing brief.

Dogs and cats

A cat is not a small dog.

It's a common mistake — treating cat nutrition as a scaled-down version of dog nutrition. Cats are obligate carnivores with distinct metabolic needs: they require more protein relative to body weight, cannot synthesise enough of their own taurine, and process fat and certain vitamins differently to dogs. That's why Keos formulates cat and dog ranges separately, from the ground up, rather than adjusting a single base recipe by species.

Cats need 11 essential amino acids; dogs need 10. The difference is taurine — essential for heart and eye health. Every Keos cat formula includes taurine as standard.

How a formula is built

The six building blocks

Every Keos formula is built around six nutritional categories, balanced against life stage and species.

01

Proteins

Muscle maintenance and tissue repair — the largest single input by cost and by importance.

02

Fats

Concentrated energy, essential fatty acids, and coat and skin condition.

03

Carbohydrates

Digestible energy sources, chosen for digestibility.

04

Vitamins

Metabolic cofactors — A, D, E and the B-complex, dosed to life stage.

05

Minerals

The calcium-phosphorus ratio, plus chelated trace minerals for bone and enzyme function.

06

Water

Moisture content kept low for shelf life, with fresh water always alongside the bowl.

The rulebook

What FEDIAF actually means

Not a logo — a nutrient specification. FEDIAF, the European Pet Food Industry Federation, publishes minimum and maximum nutrient guidelines by species and life stage. Every Keos formula is made to meet them.

The quality guarantee

Every batch is tested before it ships.

Nutrition, digestibility, stability and safety — every batch, not a sample. No exceptions.

1,000+samples tested since December 2021
100%batch conformity
18 monthsshelf stability confirmed in aging trials
40°Caccelerated stress testing at 75% humidity, by an external French laboratory
Palatability

A bowl they'll finish.

In a 2022 two-bowl preference trial, Keos Cat All Stages Seafood was chosen 66% of the time against 18% for the reference food. In 2023, Keos+ Cat Adult performed at or above Royal Canin on palatability.

Shelf stability

Verified outside the factory.

Long-term shelf stability is checked through aging trials and accelerated stress testing (40°C / 75% RH) run by an external French laboratory — proof the food holds up long after it leaves the line.
