As cats age, their nutritional needs begin to change significantly. A cat that is over seven or eight years old no longer expends energy as efficiently as it did in its youth, and becomes more prone to health problems such as obesity, joint weakness, kidney disease, and hair loss.
This highlights the importance of choosing the right food for adult cats. Many owners believe that the same diet they gave their kittens or adult cats is sufficient, but the truth is that adult cats, or "senior" cats, need a special nutritional formula that contains fewer calories, high-quality protein, carefully selected fiber, and minerals that help strengthen bones and muscles.
If you are raising a large Persian cat or any other breed, choosing food specifically for large Persian cats or other breeds will ensure a longer, healthier life, better daily activity, and even help prevent age-related diseases.
In this detailed article, we will take you on a comprehensive journey to understand everything related to the diet of senior cats, from physical changes after old age, to the best food options available, as well as a table of food for senior cats that shows the appropriate amounts according to weight and age.
What do big cats eat?

Adult cat food is specially formulated for cats over seven or eight years old, a stage marked by physiological changes that reduce their ability to digest regular food efficiently. This type of food is characterized by several features:
- Low calories:to avoid weight gain, which is one of the biggest risks to the health of adult cats.
- High-quality protein:to maintain muscle mass and prevent loss, which is common in older cats.
- Healthy fats in moderation:such as omega-3 and omega-6 fatty acids, to support healthy skin and fur.
- Dietary fibers are carefully selectedto improve digestion and prevent constipation or hairball formation.
- Targeted minerals and vitamins:such as phosphorus and magnesium to support the kidneys, and calcium to support the bones.
- Antioxidants:to combat the effects of aging such as inflammation or weakened immunity.
Compared to regular cat food, food for senior cats focuses more on nutritional balance and the precise needs that maintain the cat's health in old age.
Physiological changes after cats reach old age
Large cats face a range of natural changes that necessitate adjustments to their diet, and some of the most prominent of these changes include:
Low metabolic rate
As cats age, their calorie-burning rate decreases, meaning they may gain weight even while eating the same amount of food as when they were younger. Therefore, food for senior cats should be low in calories and suitable for weight management.
Kidney and urinary tract weakness
Older cats are prone to kidney problems and urinary stones, and therefore their food should contain a measured proportion of minerals such as phosphorus and magnesium, while promoting hydration through wet food.
Change in appetite
Some adult cats gradually lose their appetite due to a weakened sense of smell or dental problems, while others experience an excessive increase in appetite. Therefore, it is advisable to carefully monitor the adult cat's feeding schedule and adjust the portion sizes.
Joint and mobility problems
Aging brings with it joint inflammation and stiffness of movement, so adding glucosamine and omega fatty acids to the food of older cats helps to support movement and vitality.
Loss of muscle mass
With decreased activity and increasing age, a cat may gradually begin to lose muscle mass, which is why high-quality protein is considered an essential part of the diet for large Persian cats or any other breed.
Changes in fur and skin
Dryness and loss of shine are signs of aging, and this is where eating foods rich in omega fatty acids and natural oils comes in to enhance the appearance of the fur.
Types of food for large cats
The food of large cats can be divided into several main types:
Dry food
- Easy to store and economical.

Wet food
- It contains a high moisture content that promotes body hydration.
- Suitable for cats suffering from kidney or urinary tract problems.

Semi-moist food
- A mixture of dry and wet.
- Less common, but it may be a compromise for some breeders.
Natural food (Natural / Grain-free)
- It relies on natural ingredients such as meat and vegetables.
- It is usually used for cats that are sensitive or have digestive problems.
Large cat feeding schedule

It's very important to follow a feeding schedule for adult cats that takes into account the cat's weight and daily activity level. Here's a simple example:
- A cat weighing 3 kg: 45–55 g of dry food per day.
- A cat weighing 4 kg: 55–65 g of dry food per day.
- A cat weighing 5 kg: 65–75 g of dry food per day.
- A cat weighing 6 kg: 75–85 g of dry food per day.
If you are serving wet food, reduce the amount of dry food by half and replace it with wet cans or bags.
Important tips for feeding adult cats
- Distribute the meals over two or three times a day instead of one meal.
