Key Buying Factors
Protein source
Salmon is a novel, easily digestible protein that often works well for food sensitivities. We recommend a single animal protein with no by-products.
Carbohydrate type
Brown rice or other whole grains provide gentle energy without common allergens like corn or wheat. Rice is particularly well-tolerated.
Prebiotic fiber
Ingredients like beet pulp or chicory root help support healthy gut bacteria and firm up stools. Look for guaranteed levels of crude fiber around 3-5%.
Omega fatty acids
Omega-3 and -6 from sources like fish oil and flaxseed support skin health, reducing itching and dander often linked to digestive issues.
Life stage formulation
Ensure the food is labeled for growth or all life stages, with higher protein (minimum 30% dry matter) and appropriate calcium/phosphorus for large-bone development.
Texture and moisture
Wet food can be easier on sensitive stomachs due to higher moisture content, while dry kibble helps dental health. A combination approach often works best.
Care, Cost and Maintenance
Transition slowly
Mix 25% new food with 75% old food for 2-3 days, then gradually increase the proportion over 7-10 days. A sudden switch can worsen digestive issues.
Monitor stool quality
Healthy stool should be firm, chocolate-brown, and log-shaped. Loose, yellow, or mucus-covered stools indicate the diet may not be working. Consult your vet if issues persist.
Portion control
Large-breed kittens have specific calorie needs; overfeeding can strain the digestive system. Follow the feeding guide on the package and adjust based on body condition.
If your kitten still has loose stools after 3 weeks on a new food, try a probiotic supplement formulated for cats (e.g., FortiFlora) to boost beneficial gut bacteria before considering a different diet.
