Section 03
Key Buying Factors
01
Protein Content
We recommend at least 40% crude protein for active adult cats. Higher protein supports lean muscle and satiety.
02
Ingredient Sourcing
Named meat sources (chicken, duck, salmon) indicate quality. Avoid vague 'meat meal' or 'poultry by-product'.
03
Grain-Free Certification
True grain-free formulas replace grains with legumes or potatoes. Look for verified labels from the manufacturer.
04
Omega Fatty Acids
Omega-3 and omega-6 from fish oil or flaxseed promote skin and coat health. Minimum 0.5% combined is our threshold.
05
Limited Ingredient Profile
Fewer ingredients reduce allergy triggers. Ideal for cats with sensitive stomachs or food intolerances.
06
Guaranteed Analysis
Check moisture, fat, and fiber levels. Dry food should have moisture below 10% and balanced crude fat (12-18%).
Section 05
Care, Cost and Maintenance
Transition Slowly
Mix new food with old over 7-10 days, increasing ratio gradually to avoid digestive upset.
Portion Control
Feed according to weight and activity level. Use a measuring cup; free-feeding can lead to obesity.
Hydration Matters
Dry food provides minimal moisture. Always provide fresh water and consider adding wet food or broth.
Pro tip
When switching to a new grain-free food, monitor your cat's stool consistency for the first two weeks. Loose stool may indicate intolerance to a specific protein or legume.
