How is the lion supposed to lay down with the lamb and stop eating meat when cats are obligate carnivores?
An obligate carnivore is an animal that by its genetic makeup must eat the tissue of other animals in order to thrive. Obligate carnivores may eat other foods, such as vegetables, grains, or fruit, but they must eat meat as the main source of their nutrients.
In cats, taurine is indispensable for the formation of biliary salts, that are necessary for the good digestion of fats in the small intestine. Contrary to other species, the cat cannot use another amino-acid than taurine for this function. Consequently, the cat has got an important requirement for taurine that cannot be met by the hepatic synthesis from sulphurated amino-acids present in the diet. The cat relies on its dietary intake of taurine. This is an example of the cat's dependance towards animal ingredients, because taurine is not found in vegetable ingredients.
