Weight Loss in Cats: Causes and Symptoms

Weight loss in cats is generally considered a serious condition that is not easily noticed and whose effects become apparent over time. Weight loss is more common, especially in older cats, and it is important to correctly diagnose the underlying causes. To learn about the nutritional needs of older cats, click here, and to review cat foods specifically for older cats, click here.

Why Do Cats Lose Weight?

Weight loss in cats can be caused by various reasons. These include:

  • Stress: Moving, a new pet, or environmental changes can increase your cat's stress levels. Cats under stress may refuse to eat or become less hungry.
  • Health problems: Diseases such as digestive system disorders, parasites, or hyperthyroidism can cause weight loss. Chronic illnesses can also affect your cat's regular feeding. Therefore, it is extremely important to determine the causes of chronic loss of appetite and weight loss.
  • Inadequate nutrition: Choosing poor quality or incorrect food can prevent your cat from getting the nutrients it needs. Foods that do not meet the appropriate age group and energy needs can accelerate weight loss.

For detailed information, you can read our article "Why Do Cats Lose Weight?".

How to Tell if Your Cat is Losing Weight?

To understand if your cat is losing weight, you can pay attention to the following signs:

Prominent bones: If the ribs and spine are easily felt, weight loss may be the case. This sign is usually noticed in advanced weight loss. Therefore, if this point has not been reached, it is best to consult a veterinarian without delay.

Dullness of fur: Malnutrition can negatively affect the health of the fur. An unhealthy-looking coat also provides information about your cat's overall health.

Decreased energy level: A cat that is not as active as before may be struggling with weight loss. A decrease in the desire to play or a constant tendency to sleep are among the signs that support this situation.

It is not always easy to understand if cats are losing weight. It's especially difficult to notice weight loss in cats with fluffy fur. Therefore, regularly weighing cats and monitoring whether their weight is at a healthy level is the most accurate approach.

Homemade Foods That Help Cats Gain Weight

Because cats are naturally carnivores, it is vital that they are fed a healthy and balanced diet. You can support your cat with homemade foods. However, the preparation and presentation of these foods require great care. Some foods that are suitable for cats and can be beneficial when prepared and presented correctly are:

Boiled Chicken and Turkey: Protein is one of the main food sources for cats. Chicken and turkey, with their high protein values, support muscle development and weight gain. However, the presentation of the products is important: No substances that may be toxic to cats, such as spices, salt, garlic, or onions, should be added.

Boiled Fish: Fish contains omega-3 fatty acids and healthy fats. These properties support weight gain and provide energy for cats. Fish should be served boneless, boiled, and unsalted.

Eggs (Boiled or Fat-Free Omelet): Eggs are a high-quality protein source for cats. They are beneficial for weight gain and healthy muscle development. Eggs should not be given to cats raw: Consumption of raw eggs can pose a risk of salmonella.

Cottage Cheese or Yogurt (Lactose-Free or Low-Lactose): With its calcium and fat content, it supports weight gain in cats. However, it should be given in small portions to cats without lactose intolerance.

Sweet Potatoes or Pumpkin (Boiled and Pureed): These foods, containing healthy carbohydrates, are easy to digest and support weight gain. These types of foods should also be prepared without added sugar or spices.

Olive Oil: Olive oil, containing healthy fatty acids, can increase cats' calorie intake by adding a few drops to their meals. Excessive consumption should be avoided.

Grains: Adding the right grains to your cat's diet can be an important part of a healthy diet. Rice, which is easily digestible, stands out as a safe option for cats with sensitive stomachs and generally has a low risk of allergies. Oats, being rich in fiber and B vitamins, support digestion and can increase energy levels. Barley, beneficial for intestinal health, can contribute to the immune system with its fiber and vitamin content. These grains can be used in a balanced way in food ingredients, prepared correctly and according to your cat's needs. It is important to consult your veterinarian if you notice symptoms such as itching, skin problems, or digestive issues after a change in food. Liver (Boiled and Unspiced): This is a very rich source of vitamin A and protein. It contributes to weight gain. However, it should be given in moderation as excessive consumption can have toxic effects. Chicken or Bone Broth (Unsalted and Homemade): Provides moisture and calorie support. It can increase energy intake by consuming liquids in addition to food. However, it should be prepared without spices and salt. You can find details in our article "Can Meat and Bone Broth Be Given to Cats?". For detailed information on cat nutrition and to learn about safe foods for cats, you can read our article "What Do Cats Eat, What Should They Be Fed With?".

While homemade foods can be a healthy supplementary food for cats, it is always important to consult your veterinarian. Other points to remember when adding different foods to your cat's diet:

Veterinary Approval Required: Your cat's specific health condition (e.g., allergies, weight problems, or chronic illnesses) may affect the suitability of the listed foods for cats.

Balanced Nutrition Required: Homemade foods do not meet all of your cat's vitamin and mineral needs. In the long term, they should be supplemented with commercial foods or a diet recommended by your veterinarian.

Proper Cooking and Preparation: All foods must be properly cooked and completely deboned. Raw foods can increase the risk of parasites or bacterial infections in your cat.

Are Human Foods Safe for Cats?

While some foods are suitable for cats, certain human foods, such as onions, garlic, chocolate, and spicy foods, should definitely be avoided. Safe foods for your cat include plain, unseasoned meats and small amounts of cooked vegetables. However, remember that these foods should not replace your cat's regular diet.

High-Calorie Foods for Cats

Providing safe, high-calorie foods to cats that need to gain weight or have increased energy requirements is generally considered an ideal feeding option. It is important to remember that these types of foods are not suitable for every cat and should be carefully selected.

The correct use of these foods, depending on your cat's health status and specific needs, plays a critical role in both achieving desired results and preventing potential health problems.

Recommended cat food for underweight cats contains ingredients that meet your cat's daily calorie needs as well as build muscle and provide energy. These foods are enriched with flavors and aromas that make them appealing to cats with poor appetites. Offering high-calorie cat foods regularly and in a controlled manner can ensure successful results in the weight gain process. However, it should not be neglected to consult a veterinarian when choosing cat food.

Vitamin and mineral supplements can be very beneficial to strengthen your cat's immunity and support healthy weight gain. Supplements containing omega-3 fatty acids, in particular, are known to both accelerate weight gain and support coat health. Multivitamins recommended by your veterinarian can also help in the weight gain process. You can review cat-specific supplements and vitamins here.

Feeding Routines That Support Your Cat's Weight Gain

Establishing a regular and balanced feeding routine for your cat is key to ensuring healthy weight gain. Changes in feeding routines can increase your cat's appetite and make weight gain easier. This requires attention to both meal frequency and food selection.

Try Increasing the Number of Meals

One of the easiest ways to increase your cat's daily food intake is to offer small, frequent meals. Offering four or five small meals instead of two large meals a day will encourage your cat to eat more. This method can also be effective for cats with poor appetites, as smaller portions are generally more appealing.

Focus on Delicious Foods

Foods formulated to increase appetite will make your cat more willing to eat. Foods with strong aromas should be preferred, especially for cats with poor appetite or picky eaters. You can attract your cat's attention and increase its food consumption by offering chicken, salmon, or cheese-flavored foods.

Pay Attention to Balanced Weight Gain

The weight gain process should be carried out while protecting your cat's overall health. Instead of excessive weight gain, the goal should be to reach the ideal weight in a balanced and healthy way. For this, it is important to follow professional advice and consider your cat's overall activity level.

Veterinary Supervision is Important

Veterinary check-ups may become a routine requirement during your cat's weight gain process. Your veterinarian will recommend a diet and feeding plan suitable for your cat's health condition. They will also perform necessary tests to determine if weight loss is due to an underlying health problem.

Increasing Your Cat's Activity Level

In cats with low activity levels, weight gain may result in fat accumulation instead of muscle growth. Organizing playtime to encourage your cat to move more supports both weight gain and overall health. Activities that get your cat moving, such as fishing toys or cat lasers, are very helpful in this process.

Factors That Can Prevent Your Cat from Gaining Weight

You may be trying to get your cat to gain weight but not getting results. Factors that can prevent cats from gaining weight can disrupt the process of reaching their ideal weight. Potential reasons can be listed as follows:

Adapting to a Food Change

When you start giving your cat a new food, you should avoid sudden changes. When switching to a new food, you should create a transition period by mixing it into the old food little by little. Sudden food changes can increase your cat's stress level and cause it to refuse to eat. You can find details about changing cats' food here.

The Effect of Digestive Problems

Digestive system problems can prevent your cat from fully digesting food. This can make weight gain difficult. Digestive problems manifest themselves with symptoms such as diarrhea and vomiting. If you suspect digestive problems, it is important to consult your veterinarian. For detailed information, you can read our article "What Can Be Done to Improve the Digestive System Health of Cats?".

In addition to all this, the factor preventing cats from gaining weight may be another underlying disease. Therefore, weight loss in cats should not be ignored and it should be ensured that all necessary checks are carried out.

Frequently Asked Questions About Foods That Help Cats Gain Weight

In this part of our article, which we have prepared specifically about the reasons why cats are losing weight and foods that help cats gain weight, you can find the answers to the most frequently asked questions on the subject.

Why isn't my cat gaining weight?

The reasons why cats cannot gain weight are usually related to health problems, feeding errors, or stress. Health problems such as hyperthyroidism, diabetes, or parasites can prevent your cat from gaining weight. Choosing the wrong food or a low-quality diet can also cause this situation.

Which is the best food for cats to gain weight?

The best weight-gaining food for your cat will be the one recommended by your veterinarian and tailored to your cat's needs. These foods are generally formulated with high protein and calorie content. It's not accurate to say there's a single best weight-gaining food for every cat. While high-calorie foods are the primary choice for cats needing weight gain, their diets may also need to be supplemented with cat vitamins and additional nutrients. The best approach is to create a feeding plan specifically for your cat.

How much high-calorie food should I give my cat?

When giving your cat high-calorie food, you should be careful not to overdo it. You can learn your cat's daily calorie needs from your veterinarian and adjust portion sizes accordingly. Since a cat's daily calorie needs vary depending on its age, weight, and activity level, the feeding plan should be tailored to the cat.

My cat is thin but has a good appetite, is this normal?

If your cat is losing weight despite having a good appetite, this may indicate a health problem. Conditions such as parasitic infections, intestinal problems, or hyperthyroidism can cause weight loss.

Are homemade cat foods safe?

Homemade foods are safe when the right ingredients are used. Foods such as boiled chicken, fish, low-salt cheese, and yogurt can contribute to your cat's diet. However, remember that these foods should not replace cat food and may not meet all of your cat's nutritional needs. It is beneficial to create a professional feeding plan for a balanced diet.

How do I know my cat's ideal weight?

Your cat's ideal weight depends on its age, breed, and overall health. On average, a healthy adult cat can weigh between 3-6 kg. However, this varies from cat to cat. You can find detailed information in our article "What Should the Ideal Weight of Cats Be?".

Should cats be given protein or carbohydrates?

Since cats are carnivores, their primary nutritional need is protein. Carbohydrates should only be present in small amounts in your cat's diet. High-protein diets support muscle development, while excessive carbohydrate intake can lead to obesity.

Is weight loss normal in cats?

Sudden weight loss is generally not normal and may be a sign of an underlying health problem. Stress, digestive problems, infections, or chronic illnesses are potential causes of sudden weight loss. Therefore, sudden or noticeable weight loss in cats requires attention.

How to choose foods that help cats gain weight?

To support your cat's weight gain, you need to choose the right foods. Nutrient-rich and high-calorie foods can be added to the diet. While focusing on high calories, it is important to ensure that these foods are healthy and nutritionally balanced. More importantly, it is essential to be knowledgeable about the cat's overall health.
