If to conduct survey among passersby on a subject "who such obligate animals", then every second will answer that it is a predator, and will be to some extent right. Very few people from individuals with the average level of thinking know the exact answer to the question posed.
General information
Obligate call the predator feeding on exclusively animal meat, and production at the same time is comparable by the sizes with the hunter. Spiders, scorpions, some species of insects treat this look. But the main representatives obligate are all predators of the cat family.Now the cat is considered to be a pet. But once you look narrowly at the physical structure, habits, habits of individuals, to remember their relatives from the world of the wild nature (tiger, a lion, a panther, a hyena), and the opinion changes a little. Since the birth they well developed muscles, fast reactions, ability to see even at night, flexibility, inquisitiveness, dexterity – all this characteristics of an inherent predator.
Features of foodThe main difference obligate that other similar animals (such as, for example, wolf, a bear, a dog, a fox) can exist some time on vegetable food or constantly take it together with meat. The organism of a cat of it does not accept. It is because of the special anatomic structure of a stomach and composition of saliva. A stomach of the representative of the cat family very short is also not capable to acquire vegetable food. A peculiar structure of a mouth, arrangement of cutters and canines allows an animal to tear only food to pieces and to swallow, without chewing. The lower part of a cat's jaw moves only up-down, cutting big pieces of meat on smaller. As a part of cat's saliva there is no amylase. With its help vegetable food is digested. This type of livelihood is simply not necessary to obligate. The vital food of a cat are such products as meat and fish. Eating this food, the animal will always be healthy and strong. Meat contains the amino acid, most important for an organism of a cat, – taurine. Thanks to it the animal well sees. Taurine actively participates in activity of nervous and cardiovascular systems of an organism. Fish contains other vital amino acid – arachidonic. It is also very important for normal functioning of organs of vision. Greasy food sates an organism obligate practically with all types of vitamins: And, V, E, K, D. One view of an animal is enough to define his state. At a lack of food or the shortage of vitamins at an animal wool begins to drop out, claws badly grow and break.
