Types of Cat Weight Gain Supplements
Depending on the primary components, there are three basic types of cat supplements for weight gain:
- Vitamins and minerals. They are a must for well-being and healthy development. If the cat’s body lacks one mineral or vitamin, deficiency can result in health problems and, consequently, weight loss or weight fluctuations. As a rule, regular cat food contains minerals and vitamins, but their quantity and digestibility depend on the quality of products.
- Probiotics. Those are good bacteria that improve digestive health: they suppress the multiplication of bad microflora in the large intestine. Probiotics accelerate weight gain by improving gut health so that vitamins and minerals would be absorbed by the body better.
- Fatty acids. Omega-3 and Omega-6 acids promote proper organ functioning and boost the immune system. By maintaining the immune system and organs in a healthy state, such supplements contribute to healthy weight gain. Besides, they help to keep cholesterol at an optimal level, which prevents heart issues.
There are several formulations of supplements available – the choice should depend on what your cat likes more. Gel/paste formulation is very convenient: such a supplement can be given to a cat in a spoon, or you can let your feline friend lick it from your finger. You can also mix such products with food so that it would be less noticeable.
Liquid supplements are usually mixed with wet food, so a cat wouldn’t even realize there’s something added to her diet. Mixing drops with dry food isn’t good because overall food consistency might avert your cat. Some users prefer squirting liquid supplements in the cat’s mouth right from a dropper or syringe.
The powder is mixed with wet food for a cat to consume it like regular. This isn’t a good choice if your cat prefers dry food only.
Features of High-Quality Cat Weight Gain Supplements
Why weight gain supplements are widely used by cat owners and recommended by veterinarians due to the following features:
- They eliminate mineral/vitamin deficiency. By providing an optimal amount of nutrients, they improve overall health, protect inner organs, and support their functioning, help to keep the coat healthy and shiny.
- They help to achieve and maintain perfect weight. When the cat’s body has a sufficient amount of vitamins, minerals, and nutrients, it develops and grows properly. Weight loss can be prevented this way, too.
- They boost the immune system. Fatty acids and vitamins help to improve the protective functions of the cat’s body, which protects pets against illnesses or helps to recover from malaise. Health issues often suppress appetite and prevent a cat from weight gain – supplements help to eliminate this problem.
- They turbo-charge pets with energy. A higher calorie amount and a sufficient supply of vitamins and minerals improve the cat’s well-being and make it more active.
- They’re highly palatable thanks to probiotics and prebiotics for normal digestion. Such types of supplements help to maintain good microflora in the cat’s gut. As a result, metabolism improves, vitamins and minerals are digested better. Cats with a healthy intestine feel well and suffer from stomach upset less often.
- They contain healthy fats and Omega fatty acids. These components serve as the primary source of calories. Some supplements have 50% of fat – this is a high-calorie option for underweight cats.
All in all, supplements serve as a great addition to regular food and provide an optimal amount of vitamins and minerals for healthy growth and development in both kittens and adult cats. Most of these products can be given to cats of all ages and breeds.
How to Choose the Best Cat Weight Gain Supplements?
When it comes to such an important issue as the choice of weight gain supplement, you should approach it seriously and try to find the most suitable option for your feline friend.
1. Make Sure Your Cat Needs These Supplements
This is the question to start with. Why exactly do you think your cat is underweight and cannot gain extra pounds? Did you follow cat food selection 101? Is nutrition good and sufficient enough? Has your cat passed medical tests like blood analysis and tests for intestinal parasites? Is your cat recovering from certain illnesses and medical conditions? Maybe you own several cats, and one of them is being constantly attacked and prevented from eating by its pals? There might be a lot of reasons for undernourishment: you should analyze the situation properly.
Before you rush to the nearest pharmacy, visit your veterinarian. Explain your concerns to the doctor and discuss possible solutions. A professional will diagnose diseases, if any, and suggest passing some medical tests. If the cat’s health is okay, high-quality food served in appropriate amounts helps to eliminate weight deficiency.
2. Define what is lacking
If your cat is healthy (does not have dental diseases, diabetes, hyperthyroidism, kidney disease, cancer, or arthritis), you should define what might be preventing her from weight gain. First and foremost, you should organize medical tests for your cat: they will reveal the lack of certain vitamins and minerals. Even if there is a deficiency of one vital mineral and vitamin, it affects well-being and development to a large degree. Systematic undernourishment leads to problems in growth and development.
If there is no serious deficiency of vitamins and minerals, probably, your cat doesn’t get enough calories. In this case, you should consider giving more food or switching to a higher-quality option. Supplements with fat are also ideal for providing extra calories and energy.
3. Choose the supplement
Now it’s time to select the type of supplement according to the cat’s nutritional needs. Vitamin & mineral formulas will be a great addition to a regular diet and will help to restore a normal level of nutrients. Pay attention to the daily norms contained in the formula: some products are designed with the focus on certain vitamins and minerals. That’s exactly what you need to address certain deficiencies.
If your cat lacks calories and energy, choose a high-calorie supplement with 30-50% of fat. Pay attention to the original source of fats: most of them must be animal-sourced or unsaturated. Synthesized fats are no good for a cat. Also, it won’t hurt to have at least 5-10% protein content in such a product.
Supplements with prebiotics and probiotics will never hurt any cat. They can be purchased to promote the absorption of vitamins and minerals in the cat’s growing body. Even if the label doesn’t say “Store in the refrigerator,” remember to keep prebiotics in a cold place!
4. Mind what your cat likes
If your cat hates eating food with supplements added, you can try giving her gel or paste with meat flavors: apply it on your finger and let the pet lick it. Vice versa, you can add supplement drops to food and water when the previous method doesn’t work. Tablet is the worst form of a supplement because it has to be crushed before you put it in pet’s food – a rare cat will gulp large pills.
What can I give my cat to help her gain weight?
Make sure to serve high-quality cat food with all essential vitamins and minerals. Dry kibbles should have at least 30% protein and 20% fat. Wet food should have 7% protein and 5% fat. For kittens, use cat protein supplement – it will help muscle development.
Why is my cat not gaining weight?
It might be conditioned by several factors. First, lack of weight is always observed in undernourished cats: they don’t get enough vitamins, minerals, or basic nutrients (fat, protein, fat). Secondly, those components aren’t absorbed properly when a cat has intestinal problems and poor metabolism: even if it eats quality food, there might be problems with digestion and absorption. Thirdly, cats with certain illnesses have a suppressed appetite. During the recovery period, they also might find it hard to restore normal weight.
How can I get my hyperthyroid cat to gain weight?
Veterinarians recommend giving such cats wet low-carb cat food. Also, make sure that a cat drinks enough water and has access to high-calorie wet food in the morning.
Healthy nutrition is imperative for the cat’s well-being and balanced growth. If you realize that regular food is not enough for your cat, you should provide it with an additional source of calories and vitamins. Cat weight gain supplements are the best way to ensure your feline friend gets enough nutrients. Once you introduce such a product to your cat’s diet, you will see the difference in appetite, activity, and growth tempo.
However, you should realize that low weight is not always caused by undernourishment – pretty often, diseases cause problems with appetite and metabolism. Consider buying cat weight gain supplements only when you are sure about your pet’s health.
Hopefully, my guide will help you pick a suitable supplement formula. These top-10 products boast natural and well-balanced ingredients, the whole spectrum of vitamins and minerals, as well as fat of organic origin. To reap maximum out of such products and ensure their safety, please, visit a veterinarian to get professional recommendations. Do not start self-treatment of your cat – it’s dangerous!
