The high water content of wet food benefits pets prone to urinary tract issues, kidney disease, or those that drink insufficiently. Cats evolved as desert hunters and often have a low thirst drive, making wet food particularly valuable for feline hydration. Wet food tends to be more calorie-dense per dry-matter unit and more appealing to picky eaters or pets with dental pain. Downsides include higher cost per calorie, shorter shelf life once opened (refrigerate and use within two to three days), and less dental abrasion than kibble. Many owners combine wet and dry food to balance cost, dental benefits, and hydration. Always check for a complete-and-balanced AAFCO statement.
