Before you buy: 5 Things to consider before buying cat supplements and vitamins

1. Types of cat supplements

When it comes to cat supplements, you’d do well to differentiate between 3 types of them: probiotics, general vitamins and minerals, and essential fatty acids.

Probiotics are healthy, ‘good’ bacteria that help improve digestive health.

They contain microorganisms such as Lactobacillus acidophilus or Lactobacillus casei, which control the overgrowth of “bad” bacteria in the large intestine.

General vitamins and minerals are a variety of single or multivitamin products available for cats.

Most cat foods contain all the necessary vitamins and minerals that your cat needs.

Essential fatty acids or omega-3 fatty acids are known for their ability to keep a cat’s coat shiny and to prevent shedding.

They also protect a cat’s immune system, liver, eyes, brain, and joints. Additionally, omega-3 fatty acids boost heart health and fight high cholesterol.

2. Consult with your vet

Our recommendation is to always consult with your vet before giving your cat any of the products you might come across in this article.

Your vet will know whether your cat needs the vitamins and supplements you plan to give to your cat.

Giving unnecessary vitamins or supplements to your cat can do her more wrong than right.

3. Vitamins and supplements are not cures

Vitamins and supplements are merely an addition to the cure, they help support it, in case your cat is having health issues.

This means that supplements should never replace formal medicinal treatment for any diseases or conditions.

4. Vitamin and supplement ingredients that can help your cat

You shouldn’t believe everything that’s on the market. But, if you see these ingredients on the box, you should stick to them:

  • Probiotics
  • Omega 3 fatty acids
  • Vitamin E
  • Mineral oils
  • Antioxidants
  • Glucosamine
  • Chondroitin
  • Milk thistle extract

All of these ingredients can be beneficial to your cat.

5. Ingredients you should avoid

Just like there are ingredients that you should look for, there are also ingredients that you should avoid, and those include:

  • Energy supplements
  • Calcium supplements
  • Doubling up daily vitamins
  • Supplements and vitamins that weren’t tested
  • Vitamin D
  • Vitamin C
  • Garlic
  • Onion

Sometimes less is more, and that also applies to cat vitamins and supplements

Purina Pro Plan FortiFlora Cat Probiotic

If you have an elderly cat who’s more susceptible to changes in their intestinal flora, Fortiflora is guaranteed to help.

There is no need to adapt the quantity of FortiFlora to the weight or size of your cat. It is important to give the entire sachet at one feeding.

This supplement is palatable and very easy to feed – simply sprinkle one entire sachet once daily over your cat’s regular food, whether canned or dry.

Cosequin helps support cartilage production and protect existing cartilage from breakdown.

According to Cosequin, it is the only supplement that contains an exclusive combination of high purity glucosamine, low molecular weight chondroitin sulfate, and manganese ascorbate.

And it is the only glucosamine/chondroitin sulfate supplement that has been shown effective, safe, and bioavailable in published, controlled U.S. studies.

Cosequin is manufactured following standards similar to those practiced by the pharmaceutical industry.

Additionally, some vets recommend Cosequin to help support urinary bladder health.

The inner lining of the bladder wall is protected by a layer, which contains some of the same compounds as are found in cartilage.

This layer prevents urine and the waste products contained within it from seeping into and damaging the lining.

Do Cat Supplements and Vitamins Really Work?

Sometimes we have questions and doubts when it comes to these kinds of substances. Do they help? Are they necessary?

Some will tell you that these products should be seen as an extension to your cat’s diet and for her longer and happier life.

Others will tell you that giving your cat quality food is enough. So, who do we believe?

It is a fact that some cats have inherent problems in creating certain vitamins or have a certain condition that may warrant a supplement.

Vitamins and supplements were designed to fill in nutritional gaps.

If you notice that your cat is not behaving like her usual self, or that she isn’t eating the usual amount of what she normally consumes, consult your vet for supplements that can help them recover.

If in some cases, your cat eats a home-cooked or raw diet, she will most definitely need a supplement.

Certain vitamins and minerals are necessary for your cat and a home-cooked meal can’t guarantee all these ingredients.

Simply add a vet-approved supplement for home-cooked meals to make sure your pet gets all their necessary nutrients.

However, if your cat eats commercial food and doesn’t have any health problems, then it’s most likely that she won’t need a vitamin or supplement.

Cat Supplements vs. Nutraceuticals

Nutraceuticals are herbal or natural food products that improve diet and treat or prevent diseases.

However, these products aren’t tested or regulated like pharmaceutical drugs.

People who advocate for nutraceuticals claim that these products simply improve the cat’s natural diet. This is not the case.

Nutraceuticals are also, as mentioned above, products that treat or prevent diseases, which means that they are drugs and not nutritional supplements.

Nutraceutical products are found in the supplement section in pet stores and online. Some of the top sellers for cats are:

Glucosamine helps increase joint mobility and is often used as a treatment for arthritis, although it doesn’t relieve its pain.

Chondroitin is also for healthy bone and joints and it is often found with glucosamine.

Milk thistle extract helps remove toxins from the cat’s liver. It may be used for cats with liver disease.

How to give vitamins and supplements to your cat

Assess your cat’s overall health

– Take her to your vet and he will tell you which supplements your cat needs or does not need. Your veterinarian will likely warn you to not overdo it with supplements.

Give your cat only the necessary vitamins and minerals it needs – Giving it too many vitamins and minerals can hurt her health as well. If your vet agrees that your cat needs vitamins and supplements, you should buy quality products only.

If possible, buy the supplements from your vet – This way you can rest assured you’re getting a safe, quality product. Many pet stores will stock supplements for pets and you can buy them online.

Read the label carefully – When buying supplements somewhere other than your veterinary office, be sure to read all the ingredients so that you are not giving your cat more ingredients than it needs.

Follow proper dosage – When administering supplements and vitamins, it should be given according to the directions provided on the packaging or following your veterinarian’s suggestions for dosage.

Mix the supplements to your cat’s food – There are various ways that you can give supplements to your cat. Most supplements are given in forms that are easier to give to a cat, such as oils or powders that are put on food.

Health problems and which supplements and vitamins help

Heart Problem

If your cat suffers from a heart problem, there are supplements that can be given to her to improve their health, such as omega-3 fatty acids, which are usually given to cats in the form of fish oil.

No matter where you decide to purchase these products, their quality will vary and dosing information may not always be supplied.

In this case, you should look at the label to make sure the product is pure and you should discuss the dosage with your vet.

Liver Problem

If your cat has a liver problem, antioxidants might be beneficial because it can help protect liver cells.

Also, vitamin E, vitamin C, S-adenosyl-methionine, and milk thistle help in these cases. Discuss the use of these supplements with your vet before giving them to your cat.

Kidney Problem

Kidney problems can cause your cat to lose a large number of vitamins because excess urination draws water-soluble vitamins out of the body.

In order to prevent this problem, your vet may suggest supplementing your cat with vitamins B and C. Most foods are made for cats with retinal failure – this means that these foods have vitamin B and C in them.

Bone Problem

With age, your cat might develop arthritis. This is why it’s a good idea to discuss the supplements that might help its agility with your veterinarian.

The vet might suggest supplementing your cat’s diet with glucosamine and chondroitin. While these supplements will not get rid of arthritis completely, they can help to improve joint function.

Multivitamin Intake

If you give your cat multi-vitamins, there’s a chance you can create a toxic level of certain vitamins in her system.

This can occur because most cat foods provide a sufficient amount of all necessary vitamins, so giving your cat a multi-vitamin in addition to its diet can lead to an excess of vitamins.

Final Thoughts

In the long run, vitamins and supplements are helpful only when they fill in the gaps where your cat’s nutrition is lacking.

Consultation with your vet is the best way to make sure that you’re doing everything right where your cat’s health is concerned.

Whether that means cutting out on the daily vitamins or upgrading your supplement care. In the end, all we do is always for the benefit of our furry friends!

We hope we managed to answer some of your questions and concerns regarding cats’ vitamins and supplements.
