The 3 Week Challenge is a Purina ONE® mission to help more cats lead happier, healthier lives. You could see visible results week by week.

Start your cat with Purina ONE® 

With its delicious taste and high quality ingredients, Purina ONE® will provide your cat with all the nutrients she needs, and the flavours she loves.

High levels of energy and vitality

You could see your cat’s energy and vitality levels increase aided by the high quality, complete and balanced nutrition of Purina ONE®.

A healthier* digestion *Compared to a product without chicory

Purina ONE® contains chicory, a natural ingredient that is proven to help improve digestive health. Thanks to appropriate fire sources and the high digestibility of Purina ONE®, you could also notice that your cat is passing smaller, firmer stools.

Healthy skin, shiny coat, bright eyes

Purina ONE® contains specific nutrients – including Omega 3 & 6 fatty acids and essential vitamins and minerals – to help keep your cat’s skin healthy and her coat shiny. A high level of antioxidants also helps support bright, healthy eyes.

Strong natural defences

Purina ONE® Bifensis® formula contains beneficial functional bacteria proven to help support your cat's natural defences by helping to support natural antibody production.
