05
Digestibility
We evaluate fiber content and ingredient sources to ensure easy digestion and optimal nutrient absorption.

Section 05
Care, Cost and Maintenance
Transition Slowly
Introduce new food over 7-10 days by gradually mixing with the old food to avoid digestive upset.
Portion Control
Follow feeding guidelines on the package, adjusting for your cat's age, weight, and activity level to maintain a healthy body condition.
Fresh Water Always
Ensure your cat has constant access to clean, fresh water, especially when feeding dry food, to support hydration and kidney health.
Pro tip
When transitioning to a new grain-free food, mix small amounts gradually and monitor your cat's stool consistency. If you notice loose stools, extend the transition period.
Frequently asked questions
What does 'limited ingredient' mean?
Limited ingredient diets use fewer components to minimize the risk of triggering food allergies. They typically feature one protein source and few carbohydrate sources.
Is grain-free better for cats?
Many cats thrive on grain-free diets, but it's not necessary for all. Grain-free can benefit cats with grain allergies or sensitivities, but always consult your vet.
How much protein should cat food have?
We look for at least 30-40% protein on a dry matter basis, as cats are obligate carnivores requiring high protein for optimal health.
Why is taurine important in cat food?
Taurine is an essential amino acid for cats, supporting heart health, vision, and reproduction. All quality cat foods are supplemented with taurine.
Can I mix different grain-free foods?
Yes, but do so gradually to avoid digestive issues. Mixing can provide variety and different nutrient profiles, but ensure the overall diet is balanced.
