All About Proactive Kitten Supplement: Types, Benefits & More

Table of Contents

Kittens are cute, cuddly, and oh-so-sweet. But if you’re a kitten owner, you know all too well how tough caring for one can be!

One major part of proper kitten care is ensuring they’re well-fed and have all their vitamins and nutrients so that they can grow big and strong. When you put it like that, they almost sound like a cute baby brother!

The difference is that unlike kids, you can’t just tell kittens to eat their greens. That’s where supplements come in.

Kitten supplements can help balance a healthy diet and help take proactive measures in their health so they develop properly. 

The question is, what supplements should you be giving your fur babies? This guide will check out the types, benefits, and other need-to-know tidbits about your kitten’s supplements.

What to Look For in a Kitten Nutrition Supplement?

Before we jump right into which supplements to buy, let’s discuss what to look for. After all, it’s tough to go shopping if you’re not even clear about what you’re shopping for!

In general, there are five key pieces of information to keep your eyes peeled for when shopping for kitten supplements:

  1. Vet recommendations
  2. Natural ingredients
  3. Quality and brand trustworthiness
  4. Type of supplement
  5. Palatability

Let’s take a closer look at each of these factors and how to use them to pick the right supplements.

1. Veterinarian Recommendations

Most of us don’t think twice before consulting Dr. Google about our pet’s (or our own!) health. However, when it comes to choosing kitten supplements, it’s best to leave things in the hands of a professional.

Before purchasing supplements for your cats, always consult with your veterinarian. Your pets’ veterinarians know what’s best for your particular kitten, so they also know which brand or ingredients to look for in kitten supplements.

This reduces the risks of your furbabies developing unpleasant side effects. What’s more, it means that the vet can help you find supplements that don’t interfere with your kitty’s eating schedule.

2. Natural Ingredients

Another thing to keep your eyes peeled for when hunting down kitten supplements is the supplement’s ingredients list.

When looking for kitten supplements, you don’t want options loaded with chemicals and artificial substances. Artificial ingredients can also provide side effects harmful to your kittens, and can prevent them from getting the nutrients they need.

Before purchasing any supplement, do a quick read-through of the ingredients. This should quickly tell you whether you’re getting supplements that avoid harmful additives and chemicals or have unnecessary fillers.

3. Quality and Trustworthiness

We know it’s a cliche, but you’ve got to look for a quality and trustworthy brand. This is because it’s pretty easy for brands to toot their own horn and give out misleading information. As a result, you could buy something that doesn’t do what it says it will.

To find good kitten supplements, do a bit of research on the company. Look at how they source their ingredients, what processes they use to produce the supplements, and past client testimonials.

This should give you a good idea of the company’s quality, ethics, and trustworthiness.

4. Supplement Form

If you take daily vitamins yourself, then you already know these things come in multiple forms. You can find chewable or swallowable pills, liquids, and even gummies for kids.

Kitten supplements aren’t any different! You can generally find supplements in four different forms:

  • Liquid: easy to deliver with just a drop in your kitten’s mouth
  • Powder: you can mix it in food, so your cat won’t notice it
  • Gel: often called paw gel because it’s often placed on your kitten’s paws
  • Tablet: can be physically administered to your cat’s mouth or crushed up and added to food

The type of supplement you choose will depend on how easy it is to administer to your kitten as well as your cat’s preferences. Plus, it can depend on what works best to deliver a particular nutrient.

As you look for kitten supplements, think about what will be easiest to give to your cat. This can help guide you on what type of supplements to purchase.

Benefits of a Kitten Weight Gain Supplement

Although there are many reasons to look for kitten supplements, probably the most common reason is to help them gain weight. As kittens grow, they don’t always put on enough weight to continue developing healthily.

Sometimes this is because kittens aren’t hungry. Other times, it’s because of a medical issue. Either way, talking to your vet can help you identify what’s causing your kitten’s weight loss and how to fix it.

In most cases, a kitten supplement to gain weight can help put your cat back on track for meeting his milestones and developing properly. Moreover, giving your cat a kitten weight gain supplement can provide some other big benefits.

Let’s go over several key reasons to consider administering a kitten supplement to gain weight and help your kitty thrive.

They Give Your Kitten a Nutritional Boost

For one thing, kitten supplements can provide your growing fur baby with a nutritional boost. Weight-gain supplements for kittens typically have concentrated calories. These calories will provide a nutritional boost for your pet!

Now, if you’re concerned about your cat putting on too many calories, don’t panic. The calories are concentrated largely because they contain additional nutrients such as fish oils. Despite being concentrated, these actually complement your kitten’s diet!

Better yet, these supplements contain key vitamins and minerals that your cat needs to keep growing. That way, you can curb weight loss and keep your kitten growing properly.

A few nutrients that your kitten needs to grow healthily can be seen below.




  • Kittens need between 30 and 35% of their diet to contain proteins
  • At least 9% of the protein kittens receive should come from animal protein, such as from meat like chicken and fish


  • Young cats need between 18 and 35% of their diet to contain fats
  • Fats such as omega-3 fatty acids and fish oils are a great source of fat for a growing cat


They Help Combat Picky Eating

Cats are notoriously picky eaters, and if that’s the case with your kitten, you might have some trouble getting them to eat what you have on the menu. When your kittens don’t eat, they don’t reach their target weight.

Worse yet, you might notice some harmful side effects of picky eating:

  • Lethargy and tiredness
  • Less time playing and exercising
  • Diarrhea or vomiting
  • Missing fur
  • Dry skin
  • Concave or curved claws
  • Weight loss

These symptoms aren’t the same for all cats, but they are a few warning signs that show your cat’s picky eating is causing nutritional deficiencies.

The good news is that weight-gain supplements can help combat your cat’s picky eating. Since they’re packed with concentrated nutrients, your cat can get all the vitamins and minerals they need to grow healthily, even if they don’t always feel like eating their dinner.

They Boost Your Kitten’s Mood

Although most of us don’t realize it, our cat’s diets play a big role in how they feel. When your kitten gets the nutrients he needs, he becomes a happy kitten.

When he’s properly fed and nourished, he’s got the energy to romp around and explore his world. Plus, he’s not anxious, making him a healthy and happy kitten.

Just introducing supplements that ensure your kitty gets the nutrients he needs is a great way to ensure he’s a happy cat.

Now that we’ve got the benefits out of the way, it’s time to get down to business.

Administering vitamin supplements to your kittens is also a great way to ensure they have all the vitamins their bodies need. This also helps them grow healthier with enough protection from viruses and infections.

As mentioned earlier, kitten vitamin supplements often come in powders, liquids, tablets, and gels. However, you’ve also got to know about what types of vitamins to give your kitties.
