Cats Are Not Peas: A Calico History of Genetics by Laura L. GouldAfter she accidentally adopted a calico cat that turned out to be a male, Laura Gould was seized by curiosity. For there to be no male calicos at all would be understandable - it was their extreme rarity that was the puzzle. Gould, an expert in linguistics with no previous training in genetics, decided to learn how this could be. Her researches took her through the great discoveries in genetics, from Mendels studies of inheritance in peas through the discovery of the chromosome and the role of DNA - all seen from the little-known and unheralded viewpoint of the pivotal role played by cats as experimental subjects in this epic drama. Narrated with inimitable grace and wit, this is the story of an unrecognized chapter in the history of science.
5 Foods You Didn't Know Were Good For Your Cat! Vegetables and Fruit That Your Cat Can Eat!
Can Cats Eat Peas?
Dried peas belong to the family of pulses, which also includes lentils, chickpeas, and beans. As a nutrient-dense food source that is locally grown in Canada and the United States, dried yellow and green field peas are appealing to health- and environmentally-conscious consumers. Peas are used as a tool in sustainable agriculture because they are able to add nitrogen back into the soil. One of the reasons peas have become so popular in pet food is due to the increase in grain-free diets. All dry pet foods, including grain-free diets, contain a balance of carbohydrates, fats, and protein. Carbohydrates are an energy-providing nutrient that allow greater flexibility in creating pet food recipes with different nutrient levels.
Good and Bad
Cats need mostly proteins to lead a healthy life because they are carnivores. But if your cat is more tubby than tabby, you might want to introduce some veggie treats. Cats are built to tolerate a certain amount of roughage in their diets. If your cat is overweight, adding some veggies to her diet can help keep her weight down. Feeding your cat vegetables can also boost her immune system and can lessen the effects of aging. Good vegetables to offer your cat are chopped carrots, peas, frozen corn, broccoli florets, green beans, zucchini, lettuce, spinach and catnip. Do not offer garlic, onions, tomatoes, avocados or mushrooms.
There are no data that show that these diets have any health benefits for dogs and cats over more traditional diets. That is, until recently. We just published a study in the Journal of Feline Medicine and Surgery that compared ingredients and some nutrients — calories and carbohydrates — between a number of popular grain-free and grain-containing dry diets for cats. We collected ingredient and basic nutrient information on 77 dry cat diets, 42 diets that contained grain and 35 diets that were grain-free that we found for sale by large online retailers. We then determined which ingredients were most common in each category and compared nutrients between the two categories. Here are some of the more interesting things we found:. All dry cat diets contain carbohydrates of some kind.
