Cats have minimal ability to sweat, with glands located primarily in their paw pads,  and pant for heat relief only at very high temperatures  but may also pant when stressed. However, some of these products still fail to provide all the nutrients cats require,  and diets containing no animal products pose the risk of causing severe nutritional deficiencies. A proposed explanation is that cats use grass as a source of folic acid. Another is that it is used to supply dietary fiberhelping the cat defecate more easily and expel parasites and other harmful material through feces and vomit.
Carbohydrates saccharides are a group of carbon-based molecules, that are naturally found as monosaccharidesdisaccharidesor polysaccharides. Functionally carbohydrates are classified as absorbable, digestible, fermentable or non-fermentable.
When consumed in food, absorbable and digestible carbohydrates typically provide approximately 4 kcal of energy per gram, whereas fermentable and non-fermentable carbohydrates provide little to no usable energy.
Fermentable and non-fermentable polysaccharides include resistant starches formed from absorbable starch during the cooking process ; non-structural short-chain oligosaccharides, such as fructooligosaccharides FOS ; and structural non-starch polysaccharides from plant cell walls, commonly referred to as dietary fibre such as cellulose, lignin and hemicellulose.
Why are they important? Dietary carbohydrates are not considered essential nutrients for dogs and cats,  but all animals have a metabolic requirement for glucose. Additionally, the by-products of bacterial fermentation of oligosaccharides and polysaccharides short-chain fatty acids support optimal intestinal function and health.
Roles in the Body Energy Production: All cells in the body have a requirement for glucose and it must be obtained regularly either from the diet or synthesised through hepatic gluconeogenesis. Glucose absorbed from the diet can be used directly in intermediate metabolism ATP production or to synthesise glycogen and fatty acids.
Non-absorbable carbohydrates oligosaccharide and polysaccharide dietary fibres are resistant to degradation by mammalian enzymes. These carbohydrates are more commonly referred to as dietary fibres and can be divided into two broader categories depending on whether they can be further metabolized fermented by intestinal bacteria or not.
By-products of bacterial fermentation include CO, H2, methane, and the short-chain fatty acids acetate, propionate and butyrate, which can support optimal colonocyte function and intestinal health. Diffusion of acetate and proprionate across the colonic mucosa facilitates water reabsorption.
Butyrate is the preferred energy substrate of colonocytes. These forms of carbohydrates resist degradation by animal or bacterial enzymes and pass through the intestinal tract intact. Cats are able to digest and absorb dietary sugars and starches well  but have low glucokinase activity in the liver  and do not adapt carbohydrate metabolism to dietary intake.
Consequences of Deficiency Dogs: Puppies, especially small and toy breeds, may be unable to maintain blood glucose concentrations from hepatic gluconeogenesis alone and can become hypoglycaemic with low intake of dietary carbohydrates.
There are no reports of clinical signs relating to feeding carbohydrate-free diet to cats at any life-stage.
Adult cats and growing kittens are able to maintain blood glucose concentrations via hepatic gluconeogenesis. Undigested disaccharides and starches can act as osmotic agents drawing water into the intestinal lumen and can be fermented by intestinal bacteria. Animal sourced carbohydrates glycogen are also found in muscle and liver.
Diagnosing Carbohydrate Deficiency If there is low to absent carbohydrate intake with insufficient hepatic gluconeogenesis, clinical signs of hypoglycemia can occur such as lethargy and seizures.
Blood glucose concentrations below the normal laboratory reference interval will be seen on serum biochemistry profiles.
Animals consuming inadequate dietary fibre may exhibit signs of colitis e. In Nutrient Requirements for Dogs and Cats. National Academies Press p.Download over 77 felis royalty free stock video footage clips, motion backgrounds, After Effects templates, Apple Motion templates and more.
Cats, also called domestic cats (Felis catus), are carnivorous (meat-eating) mammals, of the family Felidae. The domestic cat (Felis catus or Felis silvestris catus) is a small, usually furry, domesticated, and mostly-carnivorous mammal. It is often called the housecat when kept as an indoor pet, or simply the cat when there is no need to distinguish it Order: Carnivora.
Pinnipeds, commonly known as seals, are a widely distributed and diverse clade of carnivorous, fin-footed, semiaquatic marine vetconnexx.com comprise the extant families Odobenidae (whose only living member is the walrus), Otariidae (the eared seals: sea lions and fur seals), and Phocidae (the earless seals, or true seals).
There are 33 extant species of pinnipeds, and more than 50 extinct. The domestic cat (Felis catus) Felidae are the most highly developed carnivorous hunters of all mammalian species.
With the exception of lions, which live in groups, all other wild cats have developed as solitary animals with the ability to hunt and fend for themselves.

They are often called house cats when kept as indoor pets or simply cats when there is no need to distinguish them from other felids and felines.
