Why Do Cats Eat Fish?

Cats, being obligate carnivores, are naturally drawn to a diet rich in animal protein. Fish serves as an excellent source of high-quality animal protein and essential nutrients that are crucial for their overall health. This article delves into the reasons behind a cat's preference for fish, highlighting the nutritional benefits and dispelling myths surrounding their dietary habits.

Why Cats Love Fish

Cats are obligate carnivores, meaning they require a diet composed mainly of animal sources. Fish, being a low-fat animal protein, provides a potent source of essential nutrients that contribute to a cat's health and well-being. Just as humans and birds have their preferences for fish, it's natural and expected for cats to enjoy it as part of their diet.

Wild Ancestral Diet

Despite popular belief, the wild ancestors of our domestic cats were not entirely unfamiliar with fish as prey. Many wild cats, including the African and European wildcats from which our domestic cats evolved, were known to hunt fish alongside small mammals. Fish were a common part of their ancient diets due to the abundance of aquatic life in their natural habitats. As a mother cat teaches her kittens to catch mice, they are also taught to catch fish, indicating that fish consumption is a learned and important part of their natural diet.

Nutritional Benefits

While cats might not understand human nutritional recommendations, their natural instincts lead them to choose foods that are optimal for their health. Fish, for instance, is an excellent source of high-quality animal protein, essential fatty acids, and other nutrients that are also found in other forms of meat but in varying degrees. The natural attraction of cats to healthy, nutrient-dense foods like fish underscores the importance of including such items in their diet to prevent health issues.

Myths and Realities

A cat's diet is more complex than just a love for fish. While fish is an important part of their nutritional needs, it's not the only source of animal protein they require. A cat's diet can vary widely, with some cats being particularly fond of fish while others might prefer other meats like chicken or beef. This wide array of preferences is not unusual and can be attributed to individual tastes.

Last week, I encountered a variety of dietary habits among the cats I treated, ranging from the unexpected (such as Nerf gun bullets, foam string, and even broccoli) to those that align with nutritional recommendations. Despite my efforts to guide their diets, cats often follow their instincts, leading them to consume a diverse range of items, not all of which are healthy or protein-based.

Conclusion

While cats might not eat fish just to show off, it's an important part of their diet for maintaining optimal health. Understanding the nutritional importance of fish for cats can help pet owners make informed choices about their feline companions' diet, ensuring they receive the nutrients they need to thrive.
