Why can't cats have pollock? - briefly
Cats should avoid pollock due to its high levels of histamine, which can cause allergic reactions, and its potential to contain harmful parasites or bacteria if not properly prepared.
Why can't cats have pollock? - in detail
Cats are obligate carnivores, meaning their diet must consist primarily of meat to meet their nutritional needs. While pollock, a type of fish, is a source of protein and can be included in a cat's diet in moderation, there are several reasons why it should not be a staple or sole food source for cats. First, raw or improperly prepared pollock can contain thiaminase, an enzyme that breaks down thiamine (vitamin B1). Thiamine is essential for a cat's nervous system and energy metabolism, and a deficiency can lead to severe health issues such as neurological problems, weakness, and even death. Cooking pollock can neutralize thiaminase, but relying heavily on cooked fish still poses risks. Fish-based diets, including pollock, are often high in phosphorus and magnesium, which can contribute to urinary tract issues, particularly in male cats. Additionally, fish lacks certain nutrients vital for cats, such as taurine, an amino acid critical for heart health, vision, and reproduction. While some fish may contain taurine, it is not present in sufficient quantities to meet a cat's dietary requirements. Moreover, feeding cats excessive amounts of fish, including pollock, can lead to an imbalance of fatty acids, potentially causing inflammation or skin issues. Fish can also accumulate environmental toxins like mercury and heavy metals, which, over time, can harm a cat's health. Lastly, some cats may develop allergies to fish, leading to digestive upset or skin irritations. Therefore, while pollock can be an occasional treat, it should not replace a balanced, species-appropriate diet formulated specifically for cats. A high-quality commercial cat food, supplemented with occasional safe protein sources, ensures cats receive all the nutrients they need for optimal health.
