Most commercial cat foods, whether wet or dry, do provide a sufficient amount of nutrition. So, if you have a healthy adult cat, feeding them a mix of both wet and dry food can absolutely provide them the nutritious, balanced diet they need, while still being relatively convenient and affordable. Dr. Nicole also recommends always checking the labels for a statement from the Association of American Feed Control Officials (AAFCO), which indicates the food meets the minimum nutritional requirements for cats. She also suggests checking the actual ingredients: “Look for cat foods that contain high-quality protein sources, such as chicken, turkey, beef or fish. Avoid products that contain by-products, fillers, or artificial additives, such as colors or flavors. The ingredient list should be easy to read and understand.” Sorry, Whiskers, no Cool Ranch Doritos for you!
Dr. Bruce also notes that a healthy adult cat should generally eat around 250 calories per day, and however you want to achieve that balance between wet and dry, is up to you (and of course, your cat!) and can of course vary cat by cat based on their age, health, weight, lifestyle, and preference. But the most important thing is that they eat enough food, period—there are no benefits to a cat on a self-imposed hunger strike!
Cats with specific health issues like diabetes, obesity, kidney disease, and urinary tract issues may of course require more of a certain type of food, or even a prescription diet targeted towards their health concerns, so always be sure to talk to your vet about what is the best feeding choice for your cat.
