Why do cats like fish?

Cats like fish because they are obligate carinvores. They have a long-standing reputation for being fond of fish. This is often attributed to their ancestral roots as carnivores and their natural hunting instincts. Let us explore the reasons behind cats’ love for fish and what makes this type of food so appealing to them.

It is their Natural Instinct

Cats are natural predators and are equipped with instincts that drive them to hunt and eat meat. Fish is a common prey item for many feline species in the wild, and their attraction to it is an evolved response to their natural instincts. When a cat smells fish, it triggers its predatory instincts and they are naturally drawn to it.

It has many nutritional benefits

Fish is a rich source of protein, vitamins, and minerals essential to a cat’s health. It is also high in omega-3 fatty acids, which can help to keep a cat’s coat shiny and healthy. These nutritional benefits are one reason why cats like fish so much and why it is often recommended as a supplement to their regular diet.

They like the taste and smell of fish

Fish has a strong and distinctive smell and flavour that cats find irresistible. The strong odour of fish can trigger a cat’s sense of smell and taste, making them eager to try it. Additionally, the flaky texture of fish is appealing to a cat’s palate, making it an enjoyable food for them to eat.

Fish is a familiar food for cats 

 For many cats, fish is a familiar food that they have been eating for most of their lives. Whether it’s through eating canned or dried fish-based cat food, or through catching and eating fresh fish, cats associate the smell and taste of fish with positive experiences and good times.

What are the nutritional benefits of fish for cats?

Fish can be a nutritious and beneficial food for cats, providing them with essential nutrients that support their overall health and well-being. Some of the key benefits of fish for cats include:

  •  Fish is a rich source of protein, which is essential for maintaining a cat’s muscles, skin, and fur. Cats need a high amount of protein in their diet, and fish can provide them with a good source of this important nutrient.
  •  Fish, especially fatty fish such as salmon, are high in omega-3 fatty acids. These healthy fats can help to keep a cat’s coat shiny and healthy, as well as support heart and brain health.
  • Fish is also a good source of vitamins and minerals, such as B vitamins, vitamin D, and phosphorus. These nutrients are important for maintaining a cat’s overall health and well-being.
  • The omega-3 fatty acids in fish can also help to support joint health in cats. These fatty acids have anti-inflammatory properties that can help to reduce joint pain and stiffness, making them especially beneficial for older cats.
  • The omega-3 fatty acids in fish can also help to support heart health by reducing the risk of heart disease. Additionally, fish is low in saturated fat, which can help to maintain a healthy heart.

Can cats eat raw fish?

Yes, Cats can technically eat raw fish, but it’s important to be mindful of the potential risks associated with feeding them raw fish. While some cats may enjoy eating raw fish, there are several concerns that pet owners should be aware of, including:

  • Raw fish can contain harmful bacteria such as Salmonella and E. coli, which can be harmful to both cats and humans. Cats can also be exposed to parasites such as tapeworms if they eat raw fish that is infected.
  • Fish is naturally low in thiamine, which is an essential nutrient for cats. Thiamine deficiency can lead to a range of health problems, including neurological issues, anorexia, and seizures. 
  • Feeding a cat a diet that is exclusively made up of raw fish can result in a nutrient imbalance, as fish does not contain all of the essential nutrients that a cat needs. This can lead to health problems if not addressed.

What kind of fish do cats like the most?
