The individual vitamins can not replace each other. The functions of these organic substances from animal and vegetable foods are quite specific
Fruits and vegetables five times a day: Vitamin bombs are indispensable for our health. Cats, however, can not do anything with it: they do not need to take vitamin C with their food because they can build it up in their own liver. The carotene from carrots or spinach, the provitamin A, which can transform humans in the intestinal mucosa to vitamin A, cats can not use. The mouse hunters depend on the supply of vitamin A, which is contained exclusively in animal food, such as the mouse liver. The vitamin requirement of humans and cats is therefore very different.
Healthy or poisonous – that’s what the crowd does
Vitamins are organic substances from plant and animal foods. They control, accelerate and influence innumerable bodily functions. The right dose plays a decisive role here. Both too much and too little of the fat-soluble vitamins can cause damage. Since commercial complete diets are tailored to the needs of cats, additional vitamin hunts for healthy animals are superfluous. Fat A is soluble in vitamins A, D and E. Vitamin A is important for the health of the skin, mucous membranes and eyes. Because of its lipid solubility, it can not easily be excreted through the urine, but is stored in the liver and kidney. Therefore, an over-supply of vitamin A rich food or vitamin supplements can lead to symptoms of intoxication. So beware when feeding raw beef liver, as it is a true vitamin A bomb. If the cat receives a message: Do your cat enjoy it? Skin problems, fertility and vision problems occur.
Self-catering with regard to vitamin D.
Vitamin D is essential for healthy teeth and bones. A deficiency is extremely rare, because complete food contains enough of it. An overdose of additional vitamin supplements is more likely and can lead to calcifications in the kidneys and blood vessel walls. Rich in vitamin D are especially liver, cod liver oil and fish. Vitamin E is an antioxidant with a cell-protecting effect, found mainly in grains and nuts, but low in animal foods.
Good to know
The demand increases with high-fat fish with a high content of unsaturated fatty acids. The regular excessive consumption of tuna in oil is therefore not advisable. Unlike the fat-soluble, there is no risk of overdose for the water-soluble vitamins C, H and B complex. At the same time, this means that no major vitamin stores can be stored in the body. A deficit in the various B vitamins, which fulfill different functions in the metabolism, is evident within a few weeks. For example, the ongoing shortage of vitamin B1 causes movement disorders. Rich in B vitamins are especially liver, meat and yeast. The extremely rare deficiency of vitamin H, also known as biotin, leads to dull hair and dandruff.
