No, cats should not eat only dry food. While dry food is convenient and helps with dental health, it has significant drawbacks. Cats have a low thirst drive and naturally obtain much of their water from prey. Dry food contains only about 10% moisture compared to 70-80% in wet food, which can lead to chronic dehydration and increase risks of urinary tract issues and kidney disease. A diet including wet food better mimics their natural moisture intake. Additionally, wet food is often higher in protein and lower in carbohydrates, which aligns better with cats' obligate carnivore physiology. Most veterinarians recommend either a primarily wet food diet or a combination of wet and dry food. The best approach depends on individual cat needs, but exclusive dry food feeding is generally not optimal for feline health.

The answer is highly accurate, complete, and relevant. It correctly identifies the major drawbacks of an exclusive dry food diet for cats, particularly concerning moisture intake, hydration, and the risk of urinary and kidney issues. The discussion of protein and carbohydrate levels aligning with feline obligate carnivore physiology is also excellent. The only minor point of contention is the statement that dry food "helps with dental health." While some specialized dental kibbles exist, general dry food often provides minimal dental benefits and is not a substitute for proper dental care, making this claim an oversimplification that can be misleading.

The answer accurately outlines the drawbacks of an exclusive dry food diet for cats, particularly regarding moisture content and potential health risks. It correctly highlights the dietary needs of obligate carnivores, emphasizing the importance of protein and lower carbohydrates. However, it could mention that not all dry foods are created equal, as some premium brands may offer better nutritional value. Additionally, individual cat health conditions may necessitate specific dietary adjustments, which could be more explicitly mentioned to enhance completeness.

The answer is factually accurate, covering key aspects like moisture content, hydration risks, nutritional alignment for obligate carnivores, and veterinary recommendations. It is complete and relevant to the question. Minor note: The dental health benefit of dry food is sometimes overstated, as evidence is mixed, but this does not detract significantly.
