Before You Buy
Key Buying Factors
01
Protein Source
Look for named animal proteins like chicken, salmon, or turkey as the first ingredient. Indoor cats need high-quality protein to maintain lean muscle mass.
02
Fiber Content
Fiber helps with hairball control and digestive health. Aim for at least 3-4% crude fiber from natural sources like peas or beet pulp.
03
Fat Level
Indoor cats are less active, so moderate fat (12-16%) helps prevent weight gain. Omega fatty acids support skin and coat health.
04
Limited Ingredients
For cats with food sensitivities, limited ingredient diets with a single protein source can reduce allergic reactions.
05
Added Nutrients
Look for taurine (essential for heart and eye health), probiotics, and vitamins. Avoid artificial preservatives like BHA/BHT.
06
Brand Reputation
Choose brands with a history of quality control and transparent sourcing. Check for recall history and feeding trials.
Living With It
Care, Cost and Maintenance
Transition Slowly
Switch food over 7-10 days by mixing increasing amounts of new food with old to avoid digestive upset.
Monitor Portion Sizes
Indoor cats need fewer calories. Follow feeding guidelines and adjust based on body condition score.
Provide Fresh Water
Dry food has low moisture. Ensure constant access to fresh water to support kidney and urinary health.
Pro tip
Our team recommends rotating between two high-quality grain-free foods every few months to provide nutritional variety and prevent pickiness.
Frequently asked questions
Is grain-free dry food necessary for indoor cats?
Not all cats need grain-free, but it can benefit those with allergies or sensitive stomachs. Grain-free diets often have higher protein, which aligns with a cat’s carnivorous needs.
How much should I feed my indoor cat?
Feeding amounts depend on calorie density and your cat’s weight. Typically, indoor cats need 20-30 calories per pound daily. Check the package and adjust to maintain ideal body condition.
Can grain-free food help with hairballs?
Yes, if it contains adequate fiber (around 4% or more) from sources like pea fiber or beet pulp. Fiber helps move hair through the digestive tract.
What should I look for in the ingredient list?
Look for a named protein (e.g., chicken, salmon) as the first ingredient, whole food sources for carbs, and added taurine. Avoid artificial colors, flavors, and preservatives.
Are there any risks with grain-free diets?
Some grain-free foods use legumes as fillers, which have been linked to dilated cardiomyopathy (DCM) in dogs, but the risk in cats is low. Choose a balanced food with moderate legume content.
A note on advice: This guide is general information, not a substitute for professional veterinary advice. Talk to your vet before changing your dog's diet or care routine, especially if your dog has allergies, kidney disease, pancreatitis, obesity, heart disease or any other medical condition.
