Before you assume that by-products in kitten food are bad thing, here are some facts. In common usage, a by-product is something that is just that—a side product from the making of another product. By-products are not by definition poor quality. For instance, gingerbread cookies wouldn’t be the same without molasses, which is a by-product of sugar manufacture.
In relation to IAMS™ kitten foods, such as IAMS ProActive Health™ Kitten, by-products are generally parts of the animals that are not the muscle meat preferred by most American consumers. The term refers only to the anatomic parts included, not to the nutritional quality of the parts.
While many Americans may not be used to eating these animal parts themselves, it is important to realize that many of the items included in by-products (e.g., organ meats) may be higher in essential nutrients—amino acids, minerals, and vitamins—as well as more palatable to pets than the skeletal muscle meat.
In addition to nutritional benefits, inclusion of these ingredients in pet foods reduces waste and likely has environmental benefits as the livestock industry does not have to produce additional animals just to satisfy the needs for muscle meats to feed pets as well as people. Feeding these nutrient-rich, tasty parts to pets may prevent them from being wasted and allows the entire animal to be put to good use.
Much of the consumer confusion and discomfort surrounding by-products most likely stems from the marketing strategies of some pet food brands and perhaps from the ingredient name “by-product” itself.
It is important to keep in mind that most ingredients in pet foods can vary greatly in quality. In addition, quality cannot be assessed purely on the basis of the ingredient list. All by-products are not the same quality. Neither is all muscle meat. There are very high-quality by-products as well as poor-quality chicken and chicken meal (or beef or pork).
Purchasing food only from reputable manufacturers who are very selective about their suppliers, have full-time, qualified nutritionists, and perform analytical testing to ensure that every ingredient, as well as the finished product, meets their exact nutrient specifications, will help avoid problems due to poor-quality ingredients.
Why move your nearly grown kitten to a premium adult cat food? Because quality counts. It's crucial to continue the superb nutrition she's been getting from a premium kitten food into adulthood. Downgrading to a basic nutrition brand at this stage of her life may upset her digestive system and certainly won't provide her with the same type of nutrition she was raised on.
Think of a baby. When it's time to start giving him solid food, you wouldn't feed your child anything less than the best nutrition you can buy. The same is true for your maturing kitten. She needs the best age-appropriate food there is to help maintain overall health. Premium foods such as IAMS are formulated to meet all her needs and provide additional benefits.
They're specifically designed to provide your cat with a formula that features:
High-quality ingredients
Balanced, optimal levels of protein, fat, moderately fermentable fiber, carbohydrates, vitamins, and minerals, which make costly supplements unnecessary
High-quality recipes and great taste
Standards that meet or exceed Association of American Feed Control Officials standards
Nutrient-dense formulas that are right for each life stage
Product guarantees
What do all of these features add up to? A happy, healthy cat. With premium cat food, you can expect to see these important indicators of good health. They contribute to providing your cat with a long, healthy life:
Exceptional muscle tone
A shiny, luxurious coat
Healthy skin and bones
Clear, bright eyes and clean teeth
Small, firm stools
Founded upon decades of research, premium formulas from IAMS help maintain your cat's health and help provide him with the nutrition he needs for a long life. Generic brands simply may not match the level of expertise that goes into every bag of IAMS cat food.
When your cat is about 12 months of age, it's time to change her diet to a premium maintenance formula. When you transition your cat to an adult diet, it's important to monitor her weight and body condition and adjust portions if necessary.
Because cats generally eat only what they need, free-choice feeding is adequate for most cats. (Free-choice makes food available to your cat around the clock and lets her eat when and how much she needs.) Indoor cats that don't get much exercise, however, may overeat if fed free-choice. For them, portion-controlled feeding twice a day is a better routine.
To determine how much food to give your cat, check the recommendations of the pet food manufacturer on the label. Use the guidelines and weigh your cat on a weekly basis. If your cat is gaining or losing weight and shouldn't be, slightly adjust her daily intake and weigh her again the following week.
To avoid intestinal upsets, make the change from a kitten formula to an adult diet over a period of four days with the following method:
Day One: Fill your cat's dish with 75% kitten food and 25% adult food.
Day Two: Mix adult and kitten food in a 50/50 ratio.
Day Three: Feed your cat a mixture that's 75% adult food and 25% kitten food.
Day Four: Switch to 100% adult formula.
