Metabolism refers to the complex chemical processes in the body that break down food (especially protein, carbohydrates and fat) to yield energy. The average cat metabolism can be affected by a multitude of factors, such as hormone levels, age, neuter status, illness, certain diseases, physiological states (such as pregnant or nursing), meal plan and exercise. To understand how a feline metabolism can shift continue reading.

Metabolism Fluctuates With Age
An understanding of cat metabolism and how it is impacted by life stages, food, exercise and neutering status can help cat parents understand the importance of providing proper nutrition and daily activity to feline family members.
During their first year, kittens grow a lot. Cat metabolism is very high during the kitten phase, and a complete and balanced kitten food such as Hill's® Science Diet® Kitten Healthy Development, is recommended. After your cat is spayed or neutered, your veterinarian might recommend decreasing the amount of food you feed her, as it is suspected these procedures reduce a cat's metabolic rate. If your cat is spayed or neutered before turning one, then kitten food should still be fed.
Once your cat is fully grown (approximately one year) she can be slowly transitioned to an adult formula food. Since it is much easier to prevent obesity than to reverse it, yearly veterinary examinations and weight assessments are important. Your vet will make suggestions if any meal plan changes are needed. Your cat's vet can recommend food based on her age and the American Animal Hospital Association's Body Condition Scoring, a numerical assessment that helps you to visual classify your cat as underweight, overweight or normal/ideal.
Particular care and attention is needed when your cat is middle-aged (4 to 9 years old). During this period, her metabolism slows and her caloric needs decrease. Pet parents need to be extra vigilant in monitoring their cat's weight and must provide daily exercise and activities to keep their cats mobile.
As cats enter their senior years, their metabolic rate and energy requirements once again increase. At this stage, preservation of muscle mass is very important. Feeding a specially formulated food for your senior cat, such as Hill's® Science Diet® Adult 11+ Indoor Age Defying Cat Food, provides her with a high-quality and easily digestible protein source.
