If your cat is losing weight or seems underweight, you might wonder how to help them gain some healthy pounds. As a loving cat owner, it's natural to feel worried, especially if you're doing everything right but your kitty still isn't gaining weight.
In this guide, we'll walk you through simple steps on how to fatten up a cat, covering everything from high-calorie cat foods to effective feeding tips.
Why Is My Cat Losing Weight?
Before learning how to fatten up a cat, it's important to understand why your cat might be losing weight. Weight loss in cats can sometimes mean health issues like hyperthyroidism, dental problems, parasites, or diabetes. If your cat is losing weight even though they are eating normally, consult a vet to rule out medical problems. Common causes for weight loss include:
Hyperthyroidism
A common condition in older cats that speeds up metabolism and leads to weight loss. Symptoms often include increased hunger, hyperactivity, and frequent vomiting. Treatment may involve medication, radioactive iodine therapy, or dietary changes.
Dental Problems
Sore teeth or gums can make eating painful, causing a decreased appetite. Issues like gingivitis, tooth resorption, or abscesses are common in cats. Dental cleanings and, if needed, extractions can help improve their eating ability and comfort.
Parasites
Worms and other parasites can cause weight loss by interfering with nutrient absorption. Common parasites include roundworms, tapeworms, and hookworms. Regular deworming and fecal checks are important to keep your cat parasite-free.
Diabetes
Diabetes can cause weight loss despite an increased appetite. Other signs include excessive thirst and urination. Treatment often involves insulin injections and a special diet to manage blood sugar levels.
Kidney Disease
Chronic kidney disease can cause weight loss, poor appetite, and increased thirst. Cats with kidney issues may benefit from a specialized diet that supports kidney function and helps maintain weight.
Stress or Anxiety
Changes in environment or routine can make cats lose their appetite. New pets, moving, loud noises, or even a change in feeding location can be stress triggers. Providing a calm, quiet eating space and sticking to a consistent routine can help reduce stress.
Addressing these issues is the first step to helping your cat gain weight. If your vet says your cat is healthy, then it's time to explore ways to help them gain weight safely.
The Best High-Calorie Cat Foods for Weight Gain
One of the best ways to help a cat gain weight is to provide high-calorie cat food. These foods are specially made to give extra nutrients and energy to help your cat add healthy pounds. Here are some options:
Wet Food with High Fat Content: Wet food is often tastier for cats, making it a good choice for picky eaters. Look for wet foods labeled "high-calorie" or those with high fat and protein.
Kitten Food: Kitten food can help an adult cat gain weight. It's high in calories and nutrients, making it a great way to boost your cat's intake.
Homemade Cat Food to Gain Weight: You can also make homemade cat food using boiled chicken, pumpkin, and a bit of fish oil. Make sure the recipe is safe and provides balanced nutrition for your cat.
Nutritional Supplements: High-calorie nutritional pastes and supplements can be mixed with your cat's food to provide extra calories without changing their diet completely.
How to Fatten Up A Cat: Feeding Strategies
Feeding strategies are just as important as the type of food you provide. Here are some ways to help fatten up a cat:
1. Increase Feeding Frequency
Instead of feeding your cat once or twice a day, try smaller, more frequent meals. Feeding three to four times a day can help them eat more overall. For some cats, constant access to dry food (free feeding) can also help, especially if they like to graze.
2. Make Mealtime Comfortable
Some cats are picky about their eating environment. Make sure the food bowls are clean, placed in a quiet spot, and that your cat has privacy while eating. Stress and noise can reduce their appetite.
3. Add Toppers and Treats
Adding flavor toppers or treats to your cat's food can encourage them to eat more. High-calorie cat treats are great for helping an underweight cat, especially if they're picky. Try treats made with salmon or chicken for added flavor and calories.
4. Warm Up Wet Food
Warming wet food can enhance its smell and make it more tempting for cats. Try warming it for a few seconds in the microwave to see if it helps.
How to Make Food Irresistible
A common issue when trying to fatten up a cat is their lack of interest in food. Here are some tricks to help:
Mix in Kitten Food: Mixing a bit of high-calorie kitten food with your cat's regular meals can make it more appealing and add extra nutrients.
Try Different Textures: Cats can be picky about food textures. If your cat refuses one type of wet food, try a different texture like pate, gravy-based, or shreds to see what they prefer.
Rotate Protein Sources: Cats can get bored with the same protein. Switching between chicken, beef, fish, and turkey can keep meals exciting and increase their appetite.
Homemade Cat Food Recipes for Weight Gain
If you want a natural way to help your cat gain weight, homemade cat food can be a good option. Here’s a simple recipe that’s nutritious and tasty:
High-Calorie Chicken Mix:
Ingredients:
1 cup boiled chicken (shredded)
1/4 cup pumpkin puree
1 tablespoon fish oil
1/4 cup boiled rice (optional)
Instructions:
Boil the chicken and shred it into small pieces.
Mix the chicken with pumpkin puree and fish oil.
Optionally, add boiled rice for more calories and fiber.
Always consult your vet before making major changes to your cat’s diet, especially with homemade food.
High-Calorie Supplements and Treats
If your cat isn’t gaining weight despite increased feeding, you might consider high-calorie cat food supplements.
Here are some options:
Nutritional Pastes: These come in tubes and are high in calories. You can feed them directly or mix them into their food.
Kitten Milk Replacer: Usually for kittens, but it can be added to food to increase calories for adult cats.
High-Calorie Treats: Look for treats labeled for weight gain or for senior cats, which are often more nutrient-dense.
Best Foods for Cats with Sensitive Stomachs Who Need to Gain Weight
If your cat has a sensitive stomach and also needs to gain weight, it can be challenging to find the right food. Here are some tips to help:
Choose Easily Digestible Foods
Look for foods that are easy on the stomach, such as those labeled for sensitive digestion or made with limited ingredients. These foods are designed to avoid common allergens and irritants.
High-Calorie, Limited Ingredient Options
High-calorie foods with limited ingredients can provide the extra energy your cat needs while being gentle on their digestive system. Foods with a single protein source, like turkey or lamb, can be easier for cats to digest.
Add Probiotics
Probiotics can help support your cat’s digestion and improve nutrient absorption. You can find cat food that already contains probiotics or add a probiotic supplement to their diet.
Feed Smaller, Frequent Meals
Cats with sensitive stomachs often do better with smaller, more frequent meals. This helps reduce the risk of stomach upset and ensures your cat gets enough calories throughout the day.
Consult A Vet
Always talk to a vet before making major changes to your cat’s diet, especially if they have a sensitive stomach. Your vet can recommend specific high-calorie foods that are safe and effective for cats with digestive issues.
By focusing on easily digestible, high-calorie foods, you can help your cat gain weight without upsetting their stomach. With patience and care, your cat can reach a healthy weight while staying comfortable and happy.
