Cat Food for Weight Gain Buying Guide

What Ingredients Should a Cat Food for Weight Gain Contain?

When your cat’s weight is below normal and you must take measures to help it regain its body mass and strength, you have to choose carefully. Your cat needs high-calorie cat food, but you need to pay attention to the ingredients list. There are particular compounds the must be found in weight gain food and here are some of them:

  • Real Meat

Best Cat Food For Weight GainUnderweight cats need to eat food rich in proteins that will help them regain their body fat and ensure they stay in top shape all the time. Cats are natural carnivores, which means that you need to ensure their diet includes meat.

For this reason, the best cat food for weight gain must incorporate real meat. Although there are many food brands that use a lot of artificial ingredients, these won’t be really healthy for your furry friend. You want something that is safe while helping your cat gain some weight.

Therefore, the food you buy must contain animal-based protein that will help switch from underweight to normal and healthy weight in a short time. Besides fat, the protein will also help build muscles, one important thing for the cat’s strength.

  • Fiber

Although you want your cat to gain weight, you don’t want it to escalate and cause your cat to get too fat. Having said that, fiber is one of the compounds that will make the cat feel fuller if given in the proper amounts. Thus, the kitty will not overeat.

Due to this, the cat will have good weight management and will gain the right number of pounds. Not to mention the benefits that fiber has on the digestive system, it can prevent the risk of constipation and allow food to move through the system easily. There are many high fiber cat food options available on the market as well.

  • Fats

Fat content could be a really nice addition to the cat food, which is why fats coming from animal sources should be considered. If it’s of good quality, it will help an underweight feline gain some fat and return to a healthy state.

  • Probiotics

Probiotics are so amazing because they support digestion and gut health. When you’re giving your cat an increased number of calories to aid in the weight gain process, they need to be digested easily – that’s why probiotics can help so much.

The Ingredients You Should Stay Away from When Searching for Cat Food for Weight Gain

Cat Food For Weight Gain ReviewsIf you want to know how to make a cat gain weight, you must also be aware of the ingredients that are not recommended for your feline companion. These are unhealthy and can do more harm than good. That’s why you should carefully read the ingredients list before buying any product.

Here are the compounds that you should avoid when feeding your cat:

  • Carbohydrates

Carbohydrates might be a good source of energy and calories for us humans, but cats are different. They are carnivores, which means that they don’t consume a huge amount of carbohydrates while they’re out in the wild.

Sadly, many cat foods you see in stores have carbohydrates that a kitty would not normally eat – so, they might not be the best health support out there. Besides, they are hard to digest, and will not have any impact on the weight gain process of your underweight four-legged friend.

  • Rendered Fat

Although fats are good for supporting a cat’s weight gain process, there are also fats that can be detrimental to the health of a feline. A good example is rendered animal fat, which is usually used to give more flavor to the kibbles. Even though a tasty meal would make the cat more willing to eat the food, keep in mind that rendered fat can be toxic and potentially make the pet sick. If your kitty becomes ill, weight gain won’t be your only concern, and it might be even harder to encourage it.

  • Meat By-Products

When in nature, cats eat every part of the animal, including the internal organs. By-products feature these compounds, but you should be very cautious. Sometimes, you have no idea what animal has provided said by-products in the first place. If it’s something a human wouldn’t eat, then it’s only normal that a cat shouldn’t eat it either. It might be toxic and upset the feline’s tummy, which won’t be very beneficial if you’re trying to make it gain some pounds.

  • Wheat Flour

Since cats are carnivores, they need to be given real meat, not cheap imitations. This is required in order for it to survive and have a healthy diet. That being said, wheat flour should not exist in the food you purchase for your pet. While it’s used as a source of protein sometimes, it doesn’t offer any nutritional value. It might do more harm than good, so abstain from spending money on such things.

What Else Should You Look for in a Cat Food for Weight Gain?

  • Taste

TasteThis should go without saying, but the taste is one important aspect to take into consideration if you want your feline to actually gain weight. If the food tastes bad and your cat refuses to touch the bowl until you get rid of the content, you’re not exactly helping it increase its body mass. Just like you avoid certain foods because they make you gag, a cat is no different, despite being a totally different species.

So, the food you get must taste good, preferably like meat, as cats are carnivores and adore feasting on multiple types of animals. As already mentioned, the pack or can of food you choose should contain real meat. This way, your cat won’t leave any trace in the bowl.

  • Price

Maybe the price is not the main thing that should determine your decision, but the best cat food for weight gain is usually more expensive than the average food. That doesn’t necessarily mean that you have to buy the highest-priced product out there for the best results. A product with a decent price might be just as effective and help your kitty regain its proper number of pounds.

However, you should definitely stay away from products that are ridiculously cheap. Not only that they might not help at all, but you risk buying something with a large number of unhealthy ingredients, so it’s a big no-no.

  • Calorie Level

When you need to fatten up your feline, a diet rich in calories is a must. Although you might not find a product that says exactly “High calorie” on it, you must know what type of food to choose to make sure the calorie level is high enough to encourage weight gain. For example, foods that are rich in protein and fats contain more calories and are beneficial for your cat. Therefore, go for foods that have 30% or more protein percentage, as well as a fat level between 15% and 25%. These are sure to contain the right caloric value.

Keep in mind that usually, wet food has a lower calorie content than dry cat food, which is why you must combine these types of foods.

How Do You Fatten Up a Cat?

Having an underweight cat is bad both for you and your pet. Basically, it’s sad to see your furry friend in such a condition, while for the kitty it’s unhealthy and could lead to serious issues.

Fattening up a cat is not a process that shows results overnight, but you should definitely consider implementing some methods to help your pet build some body mass.

One of the things you can do is feed it smaller amounts of food more frequently during the day. This will help the fat settle and you’ll notice your feline gaining some shape after a while.

In addition, you can try giving it kitten food, even if it’s an adult. Kitten food is known to be rich in calories, vitamins and proteins to aid with the baby cats’ growth. For this reason, it could be one of the options you have for a calorie-rich diet.

In case your cat lacks appetite, you can try warming up the food to make it more willing to approach the bowl. Heated food generally emits a stronger smell, thus it has a greater potential to draw your cat in and make it eat.

Also, don’t overlook the quality of the food. As previously mentioned, low-quality food tends to be composed of unhealthy ingredients such as fillers, which are toxic and serve no nutritional value whatsoever. They will only make your kitty’s belly feel full, while not making it gain any weight.

Why Is My Cat So Skinny But Eats All The Time?

Why Is My Cat So Skinny But Eats All The TimeYou probably know some people who eat a lot but don’t seem to gain any weight. Some cats might experience this too but be careful because it could be an indicator of a deeper health issue.

For instance, when cats become older, their hunger might become more prevalent, while they are getting thinner. One common cause behind this problem is hyperthyroidism. Basically, this is a benign tumor that forms on the thyroid gland and causes these symptoms in the first place.

Nevertheless, there are other conditions that may lead to these symptoms, such as kidney failure, diabetes or others. This is why a visit to the vet is so important and you shouldn’t overlook it under any circumstance. Maybe your vet will advise you to feed it cat food for older cats, cat food for urinary crystals or cat food for diabetic cats.

How Can You Tell If Your Cat Is Underweight?

While it depends on the breed of the cat, the average weight should be around ten pounds. Some breeds can weigh five pounds, while others can weigh fifteen pounds, which is why the proper weight is hard to determine as a general matter.

Whether a cat is underweight or not should be obvious by taking a look at it. If the rib cage is too prominent or the waist is too narrow, it’s a clear sign that you should start giving it high-calorie cat food. The prominent shoulder blades represent another indicator you should take seriously.

Thus, sometimes, you can see that the cat is thin by just looking at it. However, this doesn’t work in all cases. In certain situations, the best way to figure out if your cat is underweight is by conducting a physical analysis. This could be done by spreading your hands across its rib-cage or placing your thumbs on its backbone. Feeling the backbone is normal, but it becomes a problem when it’s way too obvious. This is a sign that the cat might be underweight. The same applies in case you feel too much of the ribs.

How Many Calories Should a Cat Eat to Gain Weight?

Just like the average weight of the cat depends on its build or breed, the same can be said about the number of calories. At the same time, it varies depending on the activity.

However, in general, if you have a 10-pound cat, it will require around 220 to 335 calories a day in order to gain enough body mass. Especially if your kitty is underweight, it will have to eat food that has about 20% fat and 30% protein – this is a great source of high calories and will definitely show results.

The Bottom Line

When trying to figure out how to get a cat to gain weight, it’s obvious that the first thing you should do is change its diet. First of all, an underweight domestic feline needs to be fed a higher number of calories. It should also get foods that contain real meat because they are a great source of protein, which it needs to gain some extra pounds.

So, make sure to follow the tips and tricks offered in this guide to find the best cat food for weight gain. You can also consider our product recommendations to help your cat recover and return to its healthy shape.
