Why Do Cats Like Fish? Can Cats Eat Fish?

The Intriguing Connection Between Cats and Fish

Cats and fish seem to have an age-old connection that has puzzled pet owners and animal enthusiasts for generations. Whether it's the sight of a shimmering fish in an aquarium or the smell of freshly cooked fish on the kitchen counter, many cats exhibit an undeniable fascination for these aquatic creatures.

In this blog article, we will explore the various reasons behind cats' attraction to fish, delving into evolutionary and behavioral factors that might shed light on this intriguing feline behavior.

Decoding Cats' Love for Fish

Instinctive Predatory Drive

One of the primary reasons why cats are drawn to fish can be traced back to their ancient hunting instincts. Cats are natural-born predators, and their ancestors relied heavily on hunting fish and other small aquatic prey to survive. Over time, this predatory drive has been ingrained in their genetic makeup, leading to an innate fascination with moving, shiny, and wriggling objects—characteristics often associated with fish.

Visual Stimulation

Cats are visually oriented animals, and their eyes are adapted to track fast-moving objects efficiently. The darting movements of fish in the water can easily catch a cat's attention, activating its hunting instincts and stimulating its playfulness. This visual stimulation can trigger a cat's innate curiosity, leading to an ongoing fascination with fish.

Why Cats Go Crazy for Fish Flavors

The Smell of Fish

The sense of smell is crucial for cats with an incredibly keen olfactory system. The aroma of fish can be highly enticing to felines due to its strong and distinct odor. This enticing scent might trigger their curiosity and desire to investigate further, even if they have never encountered live fish.

Food Reinforcement

In many households, cats are often offered fish-flavored cat food, treats, or even bits of fresh fish as an occasional treat. Positive reinforcement through food rewards can reinforce a cat's interest in fish-related stimuli. When exposed to fish in any form, they associate it with a pleasurable experience, leading to a preference for fish-related objects and scents.

Omega-3 Fatty Acids

Fish is rich in omega-3 fatty acids, which are essential for a cat's health and well-being. These fatty acids are crucial in maintaining healthy skin, a shiny coat, and supporting cognitive functions. While cats can synthesize some omega-3 fatty acids independently, obtaining them from their diet, particularly from fish, can be beneficial. As a result, cats might be naturally drawn to the aroma of fish due to their instinctual drive to seek out nutrient-rich food sources.

Variety and Novelty

Cats are curious creatures that thrive on novelty. Introducing new scents, textures, and tastes in their environment can be stimulating and enriching for them. The occasional offering of fish-flavored treats or fresh fish can be an exciting change from their regular diet, satisfying their desire for variety and novelty.

Temperature and Texture

The temperature and texture of fish might also be attractive to cats. A cool, moist fish may feel soothing to their sensitive paws, making it a tactile experience they enjoy exploring. Additionally, the texture of fish, with its slightly chewy and tender flesh, can appeal to their taste and chewing preferences.

Cultural Influence

Cultural depictions and media representations can influence the association between cats and fish. In cartoons, books, and advertisements, cats are often depicted with a strong affinity for fish, which can further perpetuate the idea and influence perceptions about cats' preferences.

Social Learning

Cats observe and learn from their environment, including interactions with their human companions. If a cat observes their owner preparing or eating fish regularly, it may develop an association between fish and positive social experiences, increasing attraction towards fish.

Emotional Fulfillment

Some experts believe that cats may associate fish with feelings of comfort and emotional fulfillment. When offered as a treat or during a special mealtime, their human caregivers' attention and positive interaction can create a positive emotional connection with fish-related experiences.


Additionally, while offering small amounts of fish as an occasional treat is safe, a diet solely consisting of fish is not recommended for cats, as it lacks essential nutrients that cats need to thrive. Always consult a veterinarian to determine your feline companion's best diet and treats.
