Neither is universally better — wet food supports hydration (important for urinary health), while dry can be convenient and may help dental health. Many cats thrive on a combination.
Urinary health
Cats evolved as desert animals with low thirst drive — wet food increases water intake.
Weight management
Dry food is calorie-dense; measure portions carefully.
Dental health
Some dry diets are formulated to reduce tartar, but brushing remains the gold standard.
