Why can't sterilized cats eat fish? - briefly
Sterilized cats should avoid eating fish due to its high mercury content and potential for causing urinary tract issues. Mercury can accumulate in their systems, leading to serious health problems, while the high phosphorus content in fish can exacerbate existing urinary tract conditions common in sterilized felines.
Why can't sterilized cats eat fish? - in detail
Sterilized cats should avoid eating fish due to several significant reasons. Firstly, fish is high in phosphorus and magnesium, which can lead to the formation of crystals in the urine. This condition, known as struvite crystals or bladder stones, is particularly problematic for sterilized cats because their urinary pH tends to be higher than that of intact cats. A higher urinary pH creates an alkaline environment where these crystals can form more easily.
Secondly, fish contains a high amount of fat and low levels of protein, which is not ideal for the nutritional needs of sterilized cats. After being spayed or neutered, cats often have a slower metabolism and are prone to weight gain. Consuming foods with a higher fat content can exacerbate this issue, leading to obesity and associated health problems such as diabetes and joint issues.
Moreover, many fish species contain high levels of mercury and other heavy metals. Prolonged consumption of these contaminated fish can lead to the accumulation of these toxic substances in the cat's body, potentially causing neurological problems and other health complications.
Lastly, raw or undercooked fish poses a risk of bacterial infections such as salmonella and listeria. Cats have sensitive digestive systems, and consuming contaminated fish can cause serious illnesses including vomiting, diarrhea, and in severe cases, sepsis.
In summary, the high levels of phosphorus and fat, potential for heavy metal poisoning, and risk of bacterial infections make fish an unsuitable food choice for sterilized cats. It is essential to provide a balanced diet tailored to their specific nutritional needs to ensure their overall health and well-being.
