What is Food for Underweight Cats?
It’s common to find cat food labelled as “weight-control” for those cats looking to shed a few pounds.
However, you won’t typically find cat food with “high-calorie” written on the label. To identify high-calorie options, you’ll need to do more research, and a good starting point is to look for cat foods that are high in protein, as they often contain more fat and calories.
Avoid foods high in carbohydrates since cats don’t process carbs efficiently, and they will only gain weight effectively if the calories come from complex sources.
The best high-calorie cat food choice for your underweight kitty should contain animal-sourced fat, ample protein, and added micronutrients.
This ensures the calories are nutritionally balanced, promoting healthy weight gain without compromising their health or immune system.
Why is My Cat Underweight?
First and foremost, it’s important to understand that you’re not a neglectful cat owner. Numerous factors could contribute to your cat’s weight loss; fortunately, many come with straightforward solutions.
As cats age, their ability to metabolise food efficiently tends to decline. This means that even if they consume their usual amount of food, their bodies may need to process and store it properly.
If your senior feline companion frequently vomits, consider switching to one of the specialised cat foods for older cats prone to vomiting.
Hyperthyroidism, an overactive thyroid, is another common issue among senior cats that can lead to weight loss.
Medical conditions like kidney disease and diabetes often increase thirst, urination, and subsequent weight loss. Similarly, diseases such as cancer and gastrointestinal problems can also contribute to this issue.

Buying Guide
Selecting the best high-calorie cat food is crucial to address weight loss and promote weight gain. This guide will walk you through the key factors to consider when choosing the right food for your underweight cat.
Cat Life Stage
Cats go through different life phases, and their nutritional requirements change accordingly. Choosing the right cat food is crucial to ensure their overall well-being.
While the variations in these requirements might seem subtle, they can significantly impact your cat’s health and happiness.
Like humans, cats have different dietary needs at various stages of life. For instance, kittens require a diet with a minimum of 30% protein, while adults can maintain their health with 26%.
Ensuring your cat’s food aligns with their life stage is essential in preventing issues like obesity and providing them with the right nutrients at the right time.
Nutrient Analysis
Cats are obligate carnivores, meaning they rely primarily on meat for their nutrition. Kittens and adult cats have specific dietary requirements for vital nutrients like vitamin A and niacin, which their bodies can’t produce independently.
Pay attention to the guaranteed analysis on the product packaging to ensure your cat’s diet is complete and balanced. Key nutrients such as arachidonic fatty acid and taurine should be in adequate amounts.
Food Calories
Determining your cat’s caloric needs is crucial to address weight gain. You can assess your cat’s body condition to identify if they are underweight. Signs of an underweight cat include little fat around the ribs, making them easily palpable.
Utilise tools like the Pet Nutrition Alliance’s calorie calculator to estimate your cat’s daily caloric intake based on the specific cat food brand you choose.
Collaborating with your veterinarian is essential to ensure a healthy weight gain strategy, as overfeeding can lead to issues like vomiting.
Ingredients

Tools like the Pet Nutrition Alliance’s calorie calculator can help you estimate your cat’s daily caloric needs based on the specific cat food brand you choose.
Collaborating with your veterinarian to develop a healthy weight gain strategy is vital because overfeeding can lead to problems like vomiting.
AAFCO Compliance: Ensuring Nutrient Profile Adherence
The best cat foods will include a statement indicating compliance with the AAFCO’s nutrient profiles for the specific species and life stage.
This certification ensures that the product contains the right mix of nutrients in appropriate amounts for optimal feline nutrition. Keep in mind that this information applies to cat diets and not treats.
Additionally, AAFCO sets standards for product names, ensuring that the name accurately reflects the product’s composition. For example, if it says “all-chicken,” it must contain only chicken.
Precautions to Take When Feeding Your Cat High-Calorie Cat Food
Several important factors must be remembered before introducing high-calorie food to your beloved feline companion. These considerations will ensure that you provide them with the best possible care.
Firstly, it is crucial to consult your cat’s veterinarian before offering any high-calorie treats designed for cats.
Ensure it is safe for your cat to consume, and inquire about the recommended duration of this dietary change, especially if the vet has prescribed it.
Secondly, when dealing with an underweight cat, it can be tempting to overindulge them. However, this can be detrimental, even when using the highest-calorie cat food.
Adhere to the recommended feeding portions indicated on the product packaging to help your cat gain weight without the risk of becoming overweight.
FAQs
How often should I feed my underweight cat?
Frequent, small meals throughout the day may be more suitable for underweight cats. Discuss a feeding schedule with your vet based on your cat’s needs.
Can I add supplements to my cat’s diet to help them gain weight?
Only add supplements after consulting your vet, as this can lead to imbalances or worsen the underlying issue. Your vet can recommend safe and appropriate supplements if necessary.
When should I see a veterinarian about my underweight cat?
If your cat has been consistently underweight or if their weight loss is sudden and unexplained, it’s crucial to consult a veterinarian. They can diagnose any underlying health problems and recommend the best course of action.
How can I encourage my underweight cat to eat more?
Try warming their food slightly to enhance its aroma, offering a variety of flavours and textures, and providing a quiet and stress-free eating environment. Your vet may also suggest appetite stimulants or feeding tubes in severe cases.
Conclusion
In conclusion, when it comes to finding the best food for underweight cats, it’s essential to prioritise nutritious calorie-rich options with a high content of animal proteins and fats. Avoiding carb-dense foods is key, as they may need to provide your feline friend the necessary fuel and energy.
If you are considering a full-stack food for cats with nutrients, Hill’s Prescription Diet i/d Digestive Care might be a worthy try. Besides, the Purina Pro Plan With Probiotics is the ideal choice for the cat’s digestion.
Whether you have a senior cat, a kitten, or any cat needing weight, there are high-calorie cat food options to ensure no cat is left behind in their journey to better health.
