The wet vs. dry debate is one of the most common questions veterinary nutritionists field. The answer is genuinely nuanced — both have legitimate roles, and the best approach for most cats is a combination.
\n\nThe Case for Wet Food
\nCats evolved as desert animals and historically got most of their water from prey. Their thirst drive is low, which means cats on dry-only diets are often chronically mildly dehydrated. This contributes to the high rates of urinary tract disease and kidney disease in domestic cats.
\nWet food is typically 70–80% moisture vs. dry food's 10%. For cats with urinary issues, kidney disease, diabetes, or constipation, wet food is often the most important dietary change a vet recommends.
\n\nThe Case for Dry Food
\nDry food is more calorie-dense and economical. It can be left out without spoiling (unlike wet, which spoils within 30–60 minutes at room temperature). Some cats prefer its texture, and it's practical for automated feeders. The dental benefit often cited for dry food is largely a myth — most cats swallow kibble whole without any scrubbing action.
\n\nReading Labels
\nThe first five ingredients tell you most of what you need to know. Look for: named protein as the first ingredient (chicken, salmon — not "poultry meal" or "meat by-products" as the primary source), no corn syrup or artificial preservatives, and a named fat source. AAFCO "complete and balanced" statement means the food meets minimum nutritional standards — look for those that achieved this through feeding trials, not just formulation.
\n\nPractical Recommendation
\nFeed wet food at least once a day (or use a wet food as the primary diet), supplement with measured portions of high-quality dry if needed for convenience. A water fountain alongside dry food also increases hydration significantly.
