What Is Katsuobushi?

And Why Do Cats Love It So Much?

Have you ever noticed that the moment you open a bag of cat treats containing dried bonito flakes—or sprinkle them over dry kibble—your cat comes running immediately? That’s because of the unique aroma and flavor of Katsuobushi, a famous ingredient in Japanese cuisine that has also become a popular component in cat food around the world.
This article will introduce you to Katsuobushi and reveal why it is so irresistible to cats.

What Is Katsuobushi?

Katsuobushi is made from skipjack tuna (bonito) that has gone through a complex preservation process lasting several months. The process begins by filleting the fish and boiling it, followed by repeated smoking and drying until the fish becomes extremely hard—almost like a piece of wood. Once fully processed, it is shaved into thin flakes or ground into a powder, which is the form most people are familiar with.

In Japanese cuisine, Katsuobushi is a key ingredient in dashi broth and is often sprinkled on dishes to enhance umami, the rich and savory taste.
For cats, however, Katsuobushi is specially produced with significantly reduced salt and sodium levels to ensure it is safe and suitable for feline health.

Why Do Cats Love the Aroma and Taste of Katsuobushi?

Cats have an excellent sense of smell and are naturally attracted to the scent of marine fish. Katsuobushi has a strong, savory aroma and is rich in free amino acids, which contribute to its deep umami flavor. In addition, it offers several nutritional benefits that appeal to cats:

• High-quality protein: Helps build and repair muscles and body tissues
• Appetite stimulation: The distinctive aroma of dried bonito helps encourage picky eaters or cats with reduced appetite
• Skin and coat support: Rich in essential fatty acids such as Omega-3 and Omega-6, promoting healthy skin and a shiny coat
• Nervous system and eye health: Contains taurine, an essential amino acid that supports heart function and vision in cats

Prebiotics in Cat Food

Prebiotics are nutrients that support the growth of beneficial bacteria in the gut (probiotics), which play a crucial role in digestive health and immune function.

Key benefits of prebiotics include:

• Improved digestion: Helps enhance digestive efficiency and prevent diarrhea or constipation
• Hairball control: Adds dietary fiber, making it easier for ingested hairballs to pass through the digestive system
• Stronger immunity: A healthy gut contributes to a stronger immune system, helping cats fight off illnesses

The Perfect Combination: Katsuobushi + Prebiotics

When Katsuobushi is combined with prebiotics in products such as Sugoi Crunchy Prebiotics with Dried Bonito, the result is dry cat food that not only tastes delicious but also supports digestive and overall health at the same time.

This combination is commonly used in many cat food products, including treats and dry kibble, to deliver dual benefits:

• Katsuobushi acts as a natural appetite enhancer, encouraging cats to eat with enthusiasm
• Prebiotics work to support gut health, ensuring better digestion once the meal is finished

With its irresistible flavor, enticing aroma, comprehensive nutritional value, and health benefits, it’s no surprise that Katsuobushi has become a favorite ingredient for many cats—making mealtime happier and more enjoyable every day.
