As cats age, their nutritional needs change. Understanding how many calories an older cat needs is essential to maintaining its health and longevity. Aging cats often experience a reduction in their activity levels and metabolism, which can lead to weight gain or loss if their diet is not adjusted accordingly. In this article, we will explore the factors that influence the caloric requirements of older cats and provide a comprehensive guide on how to meet their dietary needs.
Why Caloric Intake Matters for Older Cats
Older cats, typically those over the age of 7, have unique dietary needs compared to younger felines. As cats age, their metabolism slows down, and their energy requirements decrease. However, the nutritional quality of their diet becomes even more important. Older cats are more prone to obesity, muscle loss, and other health issues like kidney disease, diabetes, or dental problems, which can be influenced by their diet.
Caloric intake is crucial to prevent underfeeding or overfeeding. Both can lead to health problems. Underfeeding can cause malnutrition, leading to muscle wasting and weakened immune function, while overfeeding can lead to obesity, which is associated with other serious health issues like diabetes and joint problems.
Factors Influencing Caloric Needs in Older Cats
The number of calories an older cat needs varies based on several factors. These include their weight, activity level, overall health, and whether they have any underlying medical conditions. Let’s take a closer look at each of these factors:
1. Age and Weight
As cats age, their lean body mass (muscles) decreases, and their fat mass may increase if they are not kept active or on a proper diet. Generally, the caloric needs of older cats decrease by about 20-30% compared to younger, more active cats. The exact number of calories depends on the cat’s weight.
If your older cat is overweight, you may need to reduce their calorie intake to help manage their weight. On the other hand, if your cat is underweight, increasing their calorie intake might be necessary to ensure they are receiving enough energy to maintain their health.
2. Activity Level
As cats grow older, they typically become less active. Older cats may prefer lounging around rather than playing, climbing, or running. This reduction in activity leads to fewer calories being burned. Therefore, it is essential to adjust their diet to account for a lower energy expenditure. Less active cats require fewer calories to maintain their body weight.
3. Health Conditions
Health conditions such as kidney disease, diabetes, hyperthyroidism, and dental problems can all affect your older cat’s calorie requirements. Some conditions, such as hyperthyroidism, may increase a cat’s metabolism, requiring more calories, while others, like kidney disease, can cause loss of appetite and weight loss, requiring careful management of calorie intake.
How to Determine the Right Caloric Intake for Older Cats？
Determining the exact number of calories your older cat needs depends on their individual characteristics. A good rule of thumb is that an average, moderately active older cat needs approximately 20 calories per pound of body weight per day. For example, a cat weighing 10 pounds would need around 200 calories daily. However, this number can vary based on the factors we discussed above.
Basic Calorie Calculation
The general caloric needs can be calculated using the following formula:
Resting Energy Requirement (RER) = 70 × (Body Weight in kg)^0.75
Once you have the RER, you can multiply it by a factor based on your cat’s activity level and health status:
- For neutered or sedentary cats: RER × 1.2
- For active cats: RER × 1.4
- For senior cats with health conditions: RER × 1.0 to 1.2
For example, if you have a 4 kg (about 8.8 lbs) cat who is sedentary, the calculation would be:
RER = 70 × (4)^0.75 = 70 × 2.828 ≈ 197 calories
Then, multiply the RER by 1.2 for a sedentary cat:
197 × 1.2 ≈ 236 calories per day
This provides an estimate of how many calories your cat needs per day based on their weight and activity level.
Choosing the Right Diet for Your Older Cat
Once you know how many calories your older cat needs, the next step is choosing the right food. Cats require a diet that is rich in high-quality protein, moderate in fats, and low in carbohydrates. It is also crucial that their food supports their age-related needs, such as joint health, digestive health, and maintaining lean muscle mass.
1. Protein
Protein is vital for maintaining muscle mass and supporting healthy organ function. Older cats need a higher protein intake than younger cats to prevent muscle wasting. Look for foods that contain high-quality animal-based proteins such as chicken, turkey, or fish.
2. Fats
Healthy fats are also necessary for energy, and they support skin and coat health. However, excessive fat can contribute to weight gain, so it’s essential to choose a diet with an appropriate fat content for your cat’s weight and activity level.
3. Carbohydrates
Cats are obligate carnivores, meaning they do not require carbohydrates in their diet. Too many carbs can lead to obesity and other health problems. Look for foods that are low in carbohydrates and high in animal-based ingredients.
Caloric Intake and Feeding Schedule
Feeding your older cat the right amount of calories throughout the day is as important as choosing the right food. Older cats may not eat as much at each meal, so it’s a good idea to divide their daily calorie intake into two or three meals. This can help ensure they are getting enough nutrients without overeating at any given time.
Managing Overweight Older Cats
If your older cat is overweight, managing their weight becomes essential. Being overweight increases the risk of several health problems, including diabetes, arthritis, and heart disease. To help manage your cat’s weight, you can:
- Reduce their calorie intake slightly but not drastically, as rapid weight loss can be harmful.
- Increase their physical activity by encouraging play with toys or interactive games.
- Consult with a veterinarian to create a safe weight loss plan.

Conclusion
Determining how many calories an older cat needs is a crucial part of maintaining their health. By considering factors such as age, weight, activity level, and health conditions, you can provide your senior cat with the appropriate amount of food and nutrition. Always consult with a veterinarian before making any major changes to your cat’s diet, especially if your cat has underlying health conditions. With the right diet and proper caloric intake, your older cat can live a long and healthy life.
