How to Fatten Up A Cat in 7 Easy Steps With No Supplement at All!

Have you ever wondered how to fatten up a cat and help her reach an ideal weight? Although roughly 50% of cats are overweight, there are still some cats are naturally on the thin side while others lose an enormous amount of weight drastically. Whichever the case may be, it is natural for you to be the worried about your cat’s weight.

There are now many weight supplements available for pets. However, I believe that the safest way to help your cat gain weight is to go the natural route. As it is highly possible that sudden unexplained weight loss could be caused by any underlying medical problem, it might not be safe at all to give any weight gain supplement.

So, how exactly can we do this? I have put together an easy step-by-step tutorial on how to help your feline friend gain weight healthily and without the need for any medication or weight gain supplement.


Keep These Items Ready

Making your cat is no rocket science, but you will certainly need to do a bit computation here and there to monitor your cat’s progress. To do that, make sure you have the following items ready:

  • A weighing scale
  • Journal for recording
  • A variety of cat food
  • Patience – tons of it

Aside from the aforementioned items, it is also important to know the ideal weight for a cat per age. This should be the basis of your weight gain plan. Making your cat plumper than needed may also pose certain risks for her. See the following steps and get started on your cat’s weight gain plan.

Seven Steps to Fatter Cat

Step 01: Have your cat checked by a veterinarian first before engaging in a weight gain program


Just as with humans, a doctor’s advice would be essential for any weight gain or weight loss plan. Apply the same principle to your cat. Before attempting to alter your cat’s diet to make her weight gain, check what your veterinarian will have to recommend.

Your pet’s veterinarian can be better assess whether you feline friend really needs to gain weight or not. Moreover, he or she can tell you whether the current weight of your cat has something to do with any medical condition. Knowing this would inevitably help you know whether weight gain is the answer to the problem.

Know that if your cat is underweight or has lost an enormous amount of weight, there could possibly underlying medical reasons. Cancer, diabetes in cats, gastrointestinal problems, and intestinal parasites could be among the possible reasons. In addition, stress and anxiety can also be a contributing factor.

Step 02: Weigh your cat and decide on the weight goal.


Once your veterinarian gives you the green light, then it is time to develop the weight gain plan. Being by weighing your cat to calculate how much weight she should gain. You can also start with body scoring your cat. This is the process of feeling your feline’s backbone and ribs to feel how much fat covers the bone.

Another simpler approach is by using weight calculators you can find online. You simply have to input information such as the cat’s breed, current weight, and condition, and you would be able to determine whether she is at a healthy weight or not.

Step 03: Alter your cat’s diet by offering cat food that has a higher protein and fat content.


Once you know your target weight, then it is time to change your cat’s diet and introduce the new food. Assess the usual food you give her and take note of the nutritional and calorie information. As a general principle, the more calories your cat eats, the easier it is for her to gain weight.

One type of food you can slowly introduce is kitten food. As you may already know, kitten foods have the highest amount of calories, fats, and proteins. These products are generally good for thin or underweight cats of any age.

Step 04: Check for external factors


Continue to investigate as to why your cat remains underweight. If you have more than one cat at home, better check if food aggression exists among them. Other cats may be food obsessed leaving one cat underfed all the time.

Know that food aggression happens when there is not enough food for everyone. This prompts all the pets to compete for food. To foil food aggression behavior, you can try different tricks such as feeding them separately and managing meal time.

Step 05: You may opt for some home cooked meals for your cats


Who doesn’t love home cooked meals? Your feline friend would appreciate them too. An example of food you can try to offer is unseasoned scrambled eggs. These are the excellent source of fat and proteins, and cats like the taste too.

Canned food are also an excellent option. Canned sardines or mackerel contain a good level of fat and protein. See to it that you only offer can fish in water (and not in oil) and with little salt content. You can also supplement your cat’s diet with treats. Just see to it that they do not interfere with regular meal time.

Step 06: Monitor progress


Check whether your dietary changes is actually working. Weigh your cat every 5-7 days and record the information. Another equally important factor to check is whether your cat stays in good condition while gaining weight.

If you think your cat is weighing more weight that she should, make adjustments to the food quantity little by little. Abrupt changes may cause stress to your kitten. You may start by reducing the treats first and slowly reduce the amount of the main meal.

Step 07: Go back to your veterinarian once you have reached the target weight.


You need to have your cat checked again once you have successfully reached your goal. Your vet can re-assess your cat and see if the weight gain has been obtained without any negative impact on your cat. Moreover, your pet’s doctors can also give you final pointers on how to maintain the weight.

Final Reminders, Fellow Cat Lovers!

I cannot stress enough the importance of having to work hand-in-hand with your veterinarian on this matter. Your cat’s health is of paramount importance in the process. Be keen on observing any change in behavior that unfolds alongside the weight gain.
