In different phrases, a cat’s complicated dietary wants merely can’t be met by a food regimen that’s devoid of animal merchandise. On this article, we’ll discover why your cat has to eat meat to be able to thrive.

Vegan and vegetarian diets are too excessive in carbs for cats

Plant-based diets are excessive in carbohydrates; typically, greater than 50% of their energy come from carbs. All carbohydrates (besides fiber) finally break down into glucose; and refined processed carbs do that in a short time. This causes unnaturally massive swings in a cat’s blood glucose, which in flip results in insulin resistance, a precursor to diabetes.

Cats consuming carb-heavy diets additionally have a tendency to achieve weight — one other consider diabetes. They digest carbohydrates completely effectively; however they’ll solely use dietary glucose for his or her rapid power wants (that are low). The rest of the carbohydrates within the meals are rapidly and effectively saved as fats.

Cats have larger protein necessities than different animals

Whereas canine, people and different omnivores readily use carbohydrates, protein or fats for power, the feline metabolism preferentially makes use of protein for power in addition to for structuring tissues and producing hormones and different very important molecules. That’s why a cat’s protein necessities are larger than these of different animals.

Proteins are constructed from amino acids, which implies the feline requirement for particular amino acids can be larger. People want 9 important amino acids, and canine want ten, together with arginine. Cats want 11, together with arginine and taurine. A number of of those amino acids (taurine, arginine, tyrosine and carnitine) are discovered primarily in meat. For the reason that cat’s pure food regimen of uncooked prey animals incorporates these vitamins in abundance, entry to those amino acids solely turns into an issue when meat is absent. Important vitamins like these should be consumed within the food regimen; the physique can’t make them.

These amino acids should come from meat

1. Taurine

Taurine is important for mind, nerve, eye and coronary heart well being. It is usually a element of bile acids, which help within the digestion of fats. Taurine has been within the information recently as a result of canine (who have been thought to supply adequate taurine on their very own from different amino acids), have been creating dilated cardiomyopathy when fed sure business canine meals. Nonetheless, whereas taurine deficiency is a possible suspect, there could also be many different elements concerned (see “Do grain-free diets actually trigger canine coronary heart illness?”, Animal Wellness, Quantity 21, Challenge 5). Cats are additionally being affected, despite the fact that business cat meals (which regularly include inadequate high quality meat protein) are supplemented with taurine.

2. Arginine

Arginine is so vital to cats {that a} single meal containing no arginine is deadly to kittens.

3. Tyrosine

Tyrosine is taken into account conditionally important; it’s used to supply the neurotransmitter dopamine and the stress hormone adrenaline. Apparently, tyrosine deficiency will trigger a black cat’s fur to lose melanin and switch reddish-brown.

4. Carnitine

Carnitine may be made within the cat’s physique, however the skill to take action could also be impaired in circumstances of weight problems (which impacts greater than 50% of US cats), kidney illness, liver issues, and any time the urge for food is decreased.

Extra points with vegetarian and vegan diets

  • Excessive-carb diets restrict the cat’s skill to digest and soak up protein; despite the fact that there’s sufficient protein on paper, the cat could also be unable to make use of it.
  • B nutritional vitamins, particularly B1 (thiamine) and B12 are poor for a cat’s necessities.
  • Vitamin A,* discovered solely in animal tissues, can be poor. Different animals could make vitamin A from beta-carotene, however cats can not.
  • Vitamin D3,* discovered primarily within the liver, is poor. The plant-based substitute, vitamin D2, is barely 30% as potent, and has a a lot shorter period of motion.
  • The fat linoleic acid (Omega-6) and alpha linolenic acid (Omega-3) are important, and whereas each are present in greens, vegan cat meals are typically low in fats, resulting in dry pores and skin and poor coat situation.
  • Arachidonic acid, not present in vascular crops, is important for the feline immune system.
  • The Omega-3s EPA and DHA are important for kittens, and extremely useful to all cats. At the moment, obtainable vegan cat meals don’t include both.
  • Industrial vegetarian and vegan cat meals use highly-processed, fractionated, chemically-extracted and synthesized substances to offer sufficient protein and different vitamins. Complete meals containing all of the hint minerals, co-factors, and nutrient teams are far more healthy than refined or artificial variations.
  • Cats consuming meat-based diets have a naturally-low acidic urinary pH of about 5 to six. Greens trigger urine pH to change into alkaline, which can permit urinary crystals and stones to type. This could trigger life-threatening urinary blockages in male cats. A survey of 300 vegetarian- or vegan-fed canine additionally discovered the next incidence of urinary tract, ear, and different infections.

From a veterinary viewpoint, the results of feeding a vegetarian or vegan food regimen to cats are fairly anticipated to incorporate weight problems, diabetes, urinary tract illness, kidney illness, allergy symptoms, bronchial asthma, inflammatory bowel illness, liver illness, and pores and skin and coat issues. Nonetheless, veterinary diet is a younger and inexact science; we’re all nonetheless studying. Perhaps in the future these deficiencies will likely be resolved, however for now — please feed your cat a meat-based food regimen!
