Caloric intake isn't based on age it is based on weight and activity level
The ideal caloric intake can't be based on height and weight alone. Activity level (caloric expenditure) must be considered.
Caloric intake is different for different people, based on their age and their metabolism.
For male weight maintenance, easiest rule is your bodyweight (in pounds) x 10. Therefore 150 lbs = 1,500 calories. The caloric intake of any individual is dependent on many factors. Your age, natural resting metabolism, body composition and activity level will all affect your ideal caloric intake. Therefore there is no general rule in determining your caloric intake. The link below provides an estimate based on some of the factors mentioned above.
Cats gain and lose weight for the same reasons that humans do. It's based on their caloric intake and their metabolism.
Energy balance is based upon dietary/caloric intake and metabolism. Healthy weight can be based on values based on height and weight, such as the body mass index (BMI). Insufficient caloric intake can result in starvation mode, where despite less food consumed the body may gain weight, and slow metabolism. Energy balance requires the body meeting its needed caloric intake, while being exercised for cardiovascular health, and to maintain/grow lean muscle mass.
Vitamins and minerals are examples of good sources of nutrients to feed your body.

Common Vitamins are A, the B complexes, C, D, E, and K. Some minerals are calcium, copper, iron, potassium, and zinc.
The average recommended caloric intake for the average 13 year old female is 2106. For a male, it is 2234. These figures are based on weight maintenance with moderate activity. Any question relating to dieting or caloric intake should be discussed with a doctor as there are many factors to consider.
Your body needs Vitamins and Minerals EVERYDAY. If you lack Vitamins and Minerals, it will NOT protect your immune system from toxics and bacteria/viruses and your mitochondria will die on you. SO EAT YOUR VITAMINS AND MINERALS.
