Vibrissae (Whiskers) & Claws


A cat’s whiskers aid in searching by moving forward to grieve prey within sight once either the prey is just too shut or can’t be seen by the cat, in bright light or low light. The whiskers additionally develop slight vibrations alerting it to prey activity.

Cats have retractile claws for chasing when, grasping, and holding prey.

Vitamin Requirements

Cats cannot synthesize calciferol from daylight because of light 7-dehydrocholesterol in their skin and thus should receive their calciferol through dietary suggests that (animal products). Meat, eggs, and animal oil square measure wonderful supplys whereas the sole vegetarian source is mushrooms.

Vitamin A occurs naturally, only in animal tissues. While omnivores and herbivores can convert beta-carotene (an inactive form from plants) to vitamin A, cats cannot convert beta-carotene into the usable vitamin A they need and therefore need the preformed version from their diet.


“The cat’s viscus is shorter in proportion to its body size”,suggesting that the cat’s diet has very edible meat macromolecule and fat for a quick transit time as opposed to fibrous material for a chronic organic process time.

Table 1: Comparison of small intestinal length to body length in selected species.

Species Ratio

Cat        4:1

Dog       6:1

Rabbit   10:1

Pig        14:1

Intestinal length, as determined by the ratio of the intestine to body length, is clearly shorter in cats than omnivores and herbivores. The ratio for cats is 4:1, meaning that the intestines are four times longer than the length of the cat. By contrast, this ratio is 14:1 for pigs, in other words, the intestines are fourteen times longer than the length of the pig, allowing for digestion of a high carbohydrate load.

The larger stomach surface area and nonfunctioning cecum (beginning of the large intestine) in the cat, also indicate a diet of high-meat protein with higher caloric value by limiting the cat’s capability to use poorly digestible starches and fiber by bacterial fermentation in the colon. The small and simple stomach of the cat also indicates a highly digestible, multiple meal behavior.

Taste Receptors

A cat’s sense of style differs from alternative mammals in one vital means – cats have a modification that creates the sweet receptors on their tongues nonfunctional. When cats during a study were bestowed with sugar-laced water and plain water, they showed no preference for either. This mutation likely helped cats evolve toward all-meat diets.

Water Chiefly Supplied by Food

Dry food is missing the foremost vital nutrient, water. Many cats will and can live an extended life on a dry or dry/canned diet, however, we don’t know which cats are genetically able to do so until it’s too late, typically being diagnosed with chronic renal (kidney) disease. By the time most cats present with chronic renal disease, they have lost more than 70% of kidney function. This is a terminal condition.

Cats have a coffee thirst drive thanks to their desert adaptation and don’t ingest enough free water to catch up on the shortage of water in their diet, and are, therefore, chronically dehydrated.

Fatty Acid Requirements

Cats conjointly need a vital carboxylic acid, arachidonic acid, found only in meat. Cats cannot convert polyunsaturated fatty acid provided by plant sources into arachidonic acid.


Cats, through desert adaptation, require water as a component of their food. They conjointly lack the metabolic pathways to expeditiously method stuff, thus defining them as obligate carnivores; their food should consist only of meat, fat, bones, and organs. These square measure 2 terribly straightforward nevertheless elementary facts of feline nutrition.

Many feline diseases like polygenic disorder, obesity, tract disorders, chronic nephritic unwellness, and irritable internal organ syndrome may be directly attributed to low wetness, low-meat-protein, and high-carbohydrate levels that plague many of today’s commercially produced cat foods.

Many cats survive on these dry, supplemented, plant-based diets however they are doing not thrive. The following chapters will delve deeper into feline physiology explaining how a cat’s body metabolizes nutrients. With a basic understanding, optimum choices of either commercial or home-prepared foods may be chosen by the consumer to feed one’s cat.
