Kitten Diets: The Foundation of Growth

Kittens are bundles of energy, and their curious nature will keep them active around the clock. Along with their endless energy, our kittens will be growing substantially in the first year of their life and require diets developed specifically for this life stage. Kitten food provides a higher energy content, essential nutrients, proteins, fats, vitamins, and minerals in ratios that are ideal for the unique requirements of growing kittens. Because they are formulated for growth, they should be fed until they are around 90% of their expected adult body size. It can be easy to overfeed our little lions, so just like for our older cats, this particular period needs attention to portion control.

The Association of American Feed Control Officials (AAFCO) sets standards for pet foods to guarantee they meet the nutritional needs of animals at different life stages. AAFCO kitten food is specifically formulated to support the rapid growth and development that kittens experience. Kitten food, under AAFCO regulations, is designed to promote proper bone growth, support brain development, and strengthen the immune system. It contains higher levels of essential nutrients like taurine, which is critical for heart and eye health, as well as DHA, an omega-3 fatty acid important for brain and vision development. These foods are also enriched with the appropriate balance of calcium and phosphorus for healthy bone and tooth development.

Common Kitten Nutrition Misconception

Kittens on Adult Diets: Feeding kittens adult food diets so that they only have to feed all their cats one thing. Kittens need food for growth and should be on a diet formulated for kittens or for all stages.

As cats transition from kittenhood, their diets should support maintaining a healthy body weight and lean muscle mass. It’s important to understand that it is protein, not carbohydrates or fats, that makes our cats feel full. Feeding an appropriate amount of protein is essential for long-term health in cats and can also help prevent obesity.

The debate between canned vs. dry food often centers around protein and water content. Most but not all canned food diets are primarily protein and fat. They are much lower in carbohydrates than most dry diets and have much more water. Increasing the water in cat diets is often recommended as they do not have a high thirst drive.

One study showed that a 12% increase in calories resulted in 30% increase in body weight. This is very easy to do when diets are changed as the caloric content varies so much from diet to diet. It is very important to know the calories in the can of food or in the cup of kibble and learn how much your particular cat needs to maintain a healthy body weight. Obesity is avoidable!

Along with understanding their calorie intake, learning body condition scoring is an important skill for us cat owners. Cats with a body condition score of 6 actually live longer than cats with a score of 3 to 4. So slightly plump cats may live longer than skinny cats. Having a little extra fluff is okay, but, once again, remember, obesity is avoidable and causes an increased mortality rate for our felines, so let’s do this not just for the looks, but for the longevity of our cat’s lives!

Common Adult Cat Fun Fact

A fun fact I like to tell my clients is that post-spaying/neutering, our feline's energy needs decrease by 25%.

Senior Cats: A Delicate Balance

Senior diets are less straightforward, with no consensus on what constitutes "senior" food. There is evidence that most cats have a tendency to gain weight in middle age and start losing weight and muscle mass after 11 years of age. They also have less ability to digest protein and fat. Because of this, most senior diets are lower in protein and calories, which is the opposite of what we really want, although this is beginning to change. Luckily these diets are starting to change but senior recipes are still highly variable.

Senior cats' dietary needs might actually be closer to those of a kitten, requiring higher protein and calories to counteract muscle and weight loss. There really is no cookie-cutter recipe that will fit every individual.

Your veterinarian's expertise is invaluable in navigating your cat’s senior years, as we can provide tailored dietary recommendations based on your cat's specific health conditions, such as kidney function, joint health, and metabolism changes. Regular veterinary check-ups allow for early detection of age-related issues, allowing dietary adjustments to be made quickly to address specific health concerns.

Common Senior Nutrition Misconception

Older cats need less protein to protect their kidneys: Less protein equates to less palatability and less lean muscle. Protein is a critical nutrient for cats as obligate carnivores. We are rethinking the whole idea of protein restriction in cats. It is more likely that phosphorous restriction in cats with kidney disease is a beneficial alteration in the diet.

3 Practical Tips for Pet Parents

  1. Monitor Caloric Intake: Knowing the caloric content of your cat's food helps maintain a healthy weight. Regular weigh-ins at home can flag early signs of health issues.
  2. Value of Play: Don't underestimate the value of play in burning calories as well as engaging the brain and building muscle which is much more metabolically active and burns more calories than fat.
  3. Protein as a Healthy Snack: For cats, the best treats are pure protein, like dehydrated liver treats!

Navigating Nutrition Together

A cat's nutritional needs require more than a one-size-fits-all approach. It demands understanding, observation, and a willingness to adjust based on individual health and life stages.

The best guidance on your cat's nutrition comes from a professional who knows them inside and out - your veterinarian. They're not just there for health scares; they're partners in your pet’s life. Don't hesitate to reach out to them with questions about your cat's diet or health at any stage of their life.
