Must-Have Nutrients for Kittens

Welcoming a new kitten into your home is an exciting and joyful experience. As a pet parent, ensuring your kitten receives the right nutrition is crucial for their growth and development. During the kitten stage (post-weaning to 6-8 months), your little furball is gearing up to grow into a full-sized cat.

This growth phase requires a lot of energy and specific nutrients to support their rapid development. Here, we’ll explore the must-have nutrients for kittens, considering the nutrient recommendations from the National Research Council (NRC) and the Association of American Feed Control Officials (AAFCO).

Energy

Energy is not technically a nutrient, but it is a required component derived from nutrients such as protein, fats, and carbohydrates. Kittens need more energy than adult cats due to the immense energy needed to build and grow body tissues. Providing a diet rich in energy-dense nutrients ensures that your kitten has the fuel they need for their active lifestyle and growth spurts.

Protein

Cats are obligate carnivores, which means they have a high requirement for protein and for specific amino acids – the building blocks of protein. Protein is essential for muscle development, tissue repair, and growth. High-quality animal-based proteins are crucial, as they supply essential amino acids that kittens cannot synthesize on their own. Cats have higher requirements for amino acids than dogs, and kittens have an even higher need for these than adult cats. Some of these amino acids are discussed below!

  • Taurine: Did you also know that cats have more essential amino acids than us humans or even dogs? Cats have an additional requirement for the essential amino acid Taurine which is involved in heart health, vision, and the brain! 

  • Methionine: Methionine is essential for both cats and dogs - but kittens have a much higher requirement for methionine than adult cats. Methionine is important for an array of functions throughout the entire body which is why it is so important for growth!

  • Arginine: Compared to dogs, cats have a much higher requirement for arginine because cats have less ability to make arginine within the body. Arginine is required for the removal of ammonia as part of the urea cycle, as well as in immune function, hormone regulation, and cell functions. 

Calcium and Phosphorus

Bone development in kittens relies heavily on calcium and phosphorus, along with vitamin D. These minerals are vital for the formation of strong bones. Kittens require a higher amount of calcium and phosphorus in their diet compared to adult cats, and it’s important that these minerals are provided in the correct ratio. An imbalance can lead to skeletal issues and developmental problems. Ensure your kitten’s diet is formulated to meet the NRC and AAFCO guidelines for these essential minerals.

Fatty Acids

Kittens have a specific requirement for the following fatty acids: arachidonic acid, linolenic acid, and EPA and DHA. These fatty acids are an important component to your kitten’s diet and play a significant role in cognitive development, skin and coat health, and the absorption of fat-soluble vitamins (A, D, E, and K). Fats are also important for cell membrane integrity and function. Additionally, fats provide lots of energy to help kittens meet their high energy requirement during growth. Including healthy fats in your kitten’s diet supports their overall development and well-being.

Vitamins and Minerals

In addition to calcium and phosphorus, kittens need a range of vitamins and minerals to support their growth. Vitamin A is crucial for vision and immune function, while vitamin E acts as an antioxidant, protecting cells from damage. The B vitamins are important for energy metabolism and nervous system health. Trace minerals like zinc, copper, and selenium are also essential for various physiological functions. A balanced diet formulated for kittens will include these vital nutrients in the appropriate amounts.

Water

Often underestimated is water – which is essential for all life stages, including kittens. Ensure your kitten has access to fresh, clean water at all times. Proper hydration supports digestion, nutrient absorption, and overall health. Cats can sometimes struggle to get enough water intake, so encouraging hydration is important for your kitten. You can help encourage water intake by having multiple water dispensers around your home (a simple bowl of water, a flowing water fountain, etc) and by feeding a food high in moisture content!

Overall, providing your kitten with a balanced diet that meets the AAFCO nutrient recommendations is key to their healthy growth and development. Look for high-quality kitten foods to ensure they contain the right balance of essential nutrients. By giving your kitten the nutrition they need, you’re setting them up for a healthy and happy life as a full-grown cat.
