Practical information about the nutritional needs of cats and dogs at each life stage, including growth, maintenance, reproduction and aging.
Senior Cat
Cats may enter their "senior" years at about 7 years of age; however, with a typically longer life expectancy compared to dogs, this life stage can be divided into 2 categories: "mature" from 7-12 years and "geriatric" when 12 years and older. These categories are defined by some common changes that can occur in activity levels, metabolism, and ability to digest key nutrients, including fat and protein, which can affect body weight, lean body mass, immune system, digestive system, and skin. Nutrition tailored to the unique needs of cats throughout their senior years can help them live longer, healthier lives.
Senior cats begin losing lean body mass (e.g., muscle) from 7 years of age. By age 15, cats may lose an average 1/3 of their lean body mass.
Cats 7-12 years old
"While every cat is an individual, cats from 7-12 years old are typically prone to becoming overweight. Our goal is to keep your cat in ideal body condition. Regularly monitor [cat's name] at home – it is easy – simply check the waist, the tummy tuck and feel the ribs. An appropriate diet for this stage may be lower in calories and fat and higher in fiber and protein to help keep your cat in ideal body condition."
Cats over 12 years old
"While every cat is an individual, cats over 12 years of age tend to be underweight. Our goal is to keep your cat in ideal body condition. Regularly monitor [cat's name] at home – it is easy – simply check the waist, the tummy tuck and feel the ribs. If we start to notice weight loss, changing to a more calorically dense, highly digestible food with higher levels of protein may help."
Protein is a key nutrient for dogs and cats and a source of amino acids, the 'building blocks' used to build new proteins in the body. Irrespective of the pet’s age, protein plays many important roles in the body.
Although there are many benefits to maintaining a healthy weight in pets, many owners do not understand what a healthy weight is or the benefits for pets.

Feeding either wet or dry commercial cat foods, or a combination of both, will provide cats with a complete and balanced diet.
