Why Fish is Dangerous for Cats?

Even though cats really love fish, it’s not advisable to feed your cat with fish. This is because fish is not safe for cats. Below is an outline of the reasons why you should not feed your cat with fish:

• Causes urinary tract disorders.
Fish that is usually used in canned pet foods is gotten from the unsavory leftovers of seafood. These leftovers are commonly known as trash fish. It is contains bones and has high levels of magnesium and phosphorous. This is not safe for cats especially if they have a history of kidney disease or urinary track disorders. Most cats usually develop urinary track blockages and infections when they eat this canned food.

• It’s allergenic.
Most cats are highly sensitive or allergic to fish. These allergic reactions are very intense when they occur. It is ranked as one of the most common feline food allergens. These allergic reactions are as a result of high levels of histamine found in fish foods. Histamine is a protein that is usually involved in allergic reactions.

• Insufficient synthesis of vitamin K.
A bacteria that is found in the guts of cats usually help cats synthesize their own vitamin K from foods. However, this is different when it comes to fish-based foods. These foods don’t support sufficient synthesis of vitamin K in cats. This vitamin is critical for proper blood clotting.

• Development of hyperthyroidism.
Canned fish-based cat foods usually cause hyperthyroidism in cats. These cases are very common in older cats. Hyperthyroidism is a condition whereby the thyroid gland becomes very active such that the heart and other body systems start functioning very quickly. This can easily result to death in cats.

• Danger of factory-farmed fish.
Some canned fish-based foods are being made from factory-farmed fish. These fish are usually reared in overcrowded net pens found in highly polluted coastal waters. They are also fed with antibiotics, anti-fungal and dyes. These chemicals are later transferred to cats when they eat foods made from these fish. These fish are also exposed to highly toxic chemicals such as PCBs.
