How to fatten up a cat? You don’t need to worry about it because here you will definitely found the solution of your problem.

If your cat is underweight, the best way to get them back on track is, to begin with, high-quality, calorie-dense cat food that will help increase their muscle mass. Kitten food is ideal for this as it contains higher levels of protein and fat. It would be best to slowly increase the amounts you put out for them to eat until they have reached a healthy weight.

Suppose your cat continues to refuse its food despite trying different flavours. In that case, it’s still important not to panic but to seek medical attention first to rule out any possible medical issues causing the lack of appetite.

If you’re not sure how to bulk up your cat, so it stays healthy, then read on as we show you some methods and tips to taking care of your cat like a bodybuilder.

How to fatten up a cat

Some people love having a cat, and among them is the person who wants to bulk up their cats’ with a few extra pounds because they want them to feel a bit more cuddly.

They want their cat to be obese, but they want a healthy cat! Whatever the motive may be, there are certain tips and tricks you need to follow when it comes down to how to fatten up a cat properly:

1. First, check with a veterinarian

Before you decide to increase your cat’s weight:

  • Have a conversation with its veterinarian first.
  • Ask about the ideal weight ranges for different breeds of cats and discuss how much your cat should be gaining if it’s underweight or has lost interest in eating.
  • Include vitamins or medicine into this plan if such aids are recommended!
  • It’s extremely important to give regular checkups to ensure your pet remains within its healthy weight range!

2. Gradually change and increase cat food.

If you suddenly decide to change from your regular brand of cat food to a new type, the switch must be kept as gradual as possible for the cat’s health. Rather than just dumping a giant can of the new cat food into his bowl and expecting him to eat it without issue, add just a little bit of this new food into his dish and start feeding meals with more and more of it day by day until he gets used to what’s going in his mouth. Don’t worry; he won’t even notice.

3. Choose a nutrient-rich cat food.

The cat food you’re giving your pet might not have enough nutrients per serving. One way to ensure that you’re feeding your pet with the nutrition they need is by purchasing a premium cat food brand such as Wellness Signature Selects Natural Canned Grain-Free Wet Cat Food. Not all generic brands are terrible — we recommend checking the label and nutrition facts before settling on one.

4. Spice it up!

If your kitty doesn’t enjoy the food he has been served, it is time to change things up a bit by adding more flavour to your cat’s meal. Add any fish oil (your kitty might be a fan of salmon or tuna!) that helps with weight gain since it contains necessary calories and fat. If this does not work, try adding special gravy for pets into the mix. And as we all know, healthy treats are also important!

5. Kitten food

Believe it or not, many cat owners and veterinarians are starting to conclude that adult cat food may not always be the most suitable choice for overweight cats. Some believe that kittens, which need to gain more weight on average than adult cats and who tend to have more energetic metabolisms, may fare better with their more protein-rich and higher-fat kitten food. In particular, kitten food lacks fillers like corn, which has been implicated recently in causing allergies in some sensitive animals. As a recommendation, you could try tinned kitten food if your cat is a picky eater or if they’re eating less at home due to ageing; older cats may find it easier to chew!


Your beloved cat will be around for a long time if you make sure they are healthy and happy. One way to do this is by making sure they have lots of energy; they need to stay at the right weight! You can tell if your cat is too heavy or too thin. If your cat is rather slim and has little fur, then you probably don’t need to worry about weight gain because they likely do not need more calories than what they already eat. But, if your cat looks like a floating bag of skin with no muscle, then eating more might provide an extra boost. Your pet needs plenty of exercises to maintain that perfect weight; this is true for cats just as it is for humans!

Now, you’ll be able to get your cat their favourite foods and make sure that they eat up properly so your cat will stay healthy and active! You can rest easy because you’ll have some additional tools in your belt to help a kitten that used to be underweight get the nutrition he needs to grow if you have any other questions or tips about fattening up a cat, comment; below!
