 a. Animals only
 b. Plants only
 c. Both animal and plant food sources

Answers

1. c — carbohydrates. Cats are “obligate,” or “true,” carnivores, meaning they are designed to get most of their essential nutrients (vitamins, minerals, fatty acids and amino acids) from animal matter rather than plants. Carbohydrates (which are derived from plant sources) are not a necessary part of their diet. Still, most cat foods do contain some carbohydrates, typically grains or legumes. Cats can digest a small amount and do fine. Carbohydrates can be a good source of energy and fiber, which aids in fecal elimination.

2. d — essential amino acids. These include arginine, histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, valine and taurine. Deficiencies in any of these can cause serious health problems.

3. True. The proteins found in meat, poultry, fish and eggs are “complete” because they contain all of the essential amino acids cats need. The plant-based proteins found in grains, nuts, vegetables and legumes contain only some or just trace amounts of the essential amino acids. Cats are designed to eat primarily complete protein foods.

4. c — grains. Plant-based products such as grains contain only trace amounts of taurine.

5. False. It is Vitamin D that facilitates absorption of calcium and phosphorus.

6. d — fiber. Nutritionists do not classify it as a nutrient, since it is neither digested nor absorbed by the body.

7. b — ash. This is the amount of mineral deposit that remains in a sample of food after it is burned in the laboratory for two hours. Ash contains the essential minerals in a cat’s diet, such as phosphorus, potassium, manganese, magnesium, sodium and calcium. It needs to be in the right balance though. Ash content that is too high may cause urinary tract problems.

8. d — fat soluble. These are found in animal sources. The other category of vitamins — those that are water soluble — are found in liver, fish, eggs and grains. Water-soluble vitamins pass quickly through the cat’s body, while fat-soluble vitamins are stored in the body for longer periods of time.

9. c — Vitamin D. Cats get their Vitamin D when they eat a vitamin-fortified commercial diet, and it is also produced in the skin when they are exposed to sunlight. Vitamin D helps regulate the absorption of calcium and phosphorus into your cat’s body to ensure that enough of the two minerals are deposited into the teeth and bones.
 
10. True. Dietary fats (or "lipids") meet two critical needs in a cat’s diet. One, they provide a concentrated source of energy — more than twice as much per gram compared to proteins or carbohydrates. Secondly, they supply essential fatty acids, which are necessary for healthy skin and fur, along with good cell structure and function.

11. c — fiber. While there are not high levels of it in standard cat diets, some manufacturers add extra fiber in their “light” or weight-management diets to aid in the elimination of calories through the digestive tract.

12. b. This is a role of water.

13. False. Cats lack the enzyme lactase, which is necessary to digest lactose (the sugar found in milk), making them lactose intolerant. Giving a cat milk can lead to gastrointestinal upsets. The best source of calcium for cats is a complete and balanced commercial cat food that is fortified with all the essential vitamins and minerals a cat needs — including calcium.

14. d — unsaturated fats. They are found mostly in vegetable sources and include olive, canola and corn oils. Saturated fats, on the other hand, are found primarily in animal sources. (There are some vegetable fats that are saturated though, such as coconut oil, which is solid at room temperature.)

15. d — soybean meal. When essential amino acids are missing or present in very reduced amounts, the ingredient is considered an "incomplete protein source." Plant-based food sources are considered incomplete protein sources. Meats, poultry, fish and eggs, on the other hand, have complete amino acid profiles and the best types of protein to feed to cats.

16. False. Essential amino acids and fatty acids are those your cat must consume in its diet. However, your cat’s body is able to manufacturer nonessential amino acids and fatty acids inside its body.

17.  c — Vitamins C and E. Many cat-food manufacturers are now adding Vitamin E to their diets to decrease levels of oxidative stress or amounts of peroxides and free radicals that can damage cells and tissues. As far as the other vitamins: Vitamin A is for skin; B vitamins are for healthy muscles, skin and blood; vitamin D is for healthy bones and teeth; and Vitamin K is known as the blood- clotting vitamin.

18. a — arachidonic acid. This is an omega-6 fatty acid, which is an essential nutrient in your cat’s diet. Dogs, people and other omnivores need arachidonic acid, too, but they are able to get it from plant sources, converting the linoleic acid (another omega-6 fatty acid) found in vegetable oils to arachidonic acid. The cat body can't do this. Cats must derive their arachidonic acid from animal fat, which is another reason why they need to eat a meat-based diet.

19. True. Cats are better able to process the more complete, animal-based protein sources (meat, poultry, fish, eggs).

20. c — fatty acids. These are specific types of polyunsaturated fats. They are essential for the proper functioning of many of the cat’s body systems, including the integumentary (skin and coat), circulatory, reproductive and immune systems.

21. Essential. These are nutrients cats can only get if they eat animal tissue (from prey animals or meat-based commercial cat food). Cats are not able to manufacturer these nutrients in their bodies. Nonessential nutrients, however, can be synthesized inside the cat’s body.

22. False. Too many vitamins in the diet can cause a slew of problems for cats, including fatigue, muscle weakness, abdominal bloating, vomiting and diarrhea. Most high-quality, commercially made cat diets contain balanced levels of vitamins adequate to meet the cat’s needs. If a cat is given vitamin supplements on the side, there can be vitamin excesses, and all the potential problems associated with that.

23. False. The cat’s gastrointestinal system is specialized to digest entire animals. That includes the "extra parts" derived from slaughtered animals, such as the liver, lungs, spleen, brain, blood, bone and other so-called by-products. Of course, some by-products, like beaks and hooves, are very low quality, nondigestible protein sources, and these should be avoided.

24. True. Water is especially important for cats that are on dry diets (which generally contain only 10 percent moisture, compared to 70 percent-80 percent moisture for most canned foods). However, even cats on a total canned-food diet need a constant source of water. Water is important for regulation of body temperature, elimination of waste, digestion of food and good kidney health.

25. c — both animal and plant food sources. Most of the mineral sources in commercial cat foods come from bone and meat meals. However, many of the grains and legumes used in cat food contain trace amounts of phosphorus, magnesium, iron, potassium, etc., (plants absorb these inorganic substances from the water and soil), and these add to the food’s mineral content as well.

How you scored
Give yourself one point for each correct answer in this challenging quiz, and then tally up the total.

20-25: Impressive score! Give yourself a pat on the back. You know your nutrition, and probably you and your cat are both eating a healthy diet.

10-19: You’re right in the middle of the bell curve. You know something about the most important ingredients to look for on a pet-food label, but you’re not exactly a nutrition expert.

9 or below: Chances are, science was not your favorite subject in high school. You might want to re-read the questions and answers in this quiz to try to understand what you didn’t get correct. Everyone should understand at least the basics of good nutrition — for their pet's sake and for themselves!

I have recently learned that canned food with no grains and dry food with no grains are necessary for a cat that suffers from interstitial cystitis or just cystitis. The grains cause an imbalance in their urine that causes this condition. My cat is has changed quite a lot since I instituted these measures. I received this information from a Vet that specializes in nutition for cats and has a cat only clinic.

This really needs to be an interactive quiz! With all that back and forth, to see the answers to the questions, I don't know my score or what I might have learned either . . . Gave up before finishing.
