How do cats usually get their fiber?

Cats usually get their fiber from the food they eat. For example, wet food that is purpose-made for cats. This food usually has the ingredients listed and lets you know how much fiber, along with other nutrients, is contained in it.

However, it is important to learn how to interpret these listed ingredients because they often refer to crude fiber, and this can be confusing when compared to the standard human food label.

How do I give my cat more fiber?

You can give more fiber to your cat in a few ways. For example, supplementation, pet food, or a formulated diet from your vet (therapeutic). The last two are usually deemed as the best choice because they are formulated for your cat’s needs.

But, if your vet is OK with fiber supplementation, this is still a viable option.

Can cats consume too much fiber?

Cats can easily consume too much fiber. This is because they are designed differently to us humans. in particular, their digestive tract length. This is shorter than ours and one of the reasons they are best suited to a meat-based diet.

What cats typically benefit from fiber supplementation?

Cats that are suffering from constipation or have issues with obesity typically benefit from fiber supplementation. However, it’s best to consult with your vet first before proceeding with it to make sure they agree. In some cases, they may request a different solution.

What features to look out for in a Fiber Supplement?

Before you rush out and choose a random alternative to Peridale granules it is important to understand the features that you should consider. Let me explain now…

  • Mixes Well
  • Recommended by vets
  • Natural ingredients
  • Guarantees
  • Helps with anal gland issues

Mixes Well

This benefit goes without saying. Not many cats will love any supplement in its raw form, are you with me? Therefore, it is important that it can easily be mixed with other food, to mask the taste basically.

Recommended by vets

Who doesn’t like a vet recommendation? Exactly, I am no different. If the vendor makes a bold claim like this. Then it is a good indication that the product is a good choice.

Natural ingredients

When it comes to ingredients, natural is always best, right? It is not always possible, but the more natural, the better in my opinion.


When a vendor makes a guarantee, it sends a very clear message. It says that they stand by their product. It is basically the same as them putting their money where their mouth is, are you with me?

Helps with anal gland issues

Finally, I like any product that I select to help with anal gland issues. This causes big issues for cats such as inconsistent stools and other fecal problems. So, I need the product to deliver on this.

Best High Fiber Supplements for Cats

What is the best Peridale Granule alternative? This is the best Peridale Granule alternative (Click here to see the reviews on Amazon) in my opinion. I say this because it can be mixed with food easily. And,  helps with constipation, anal gland problems, digest issues as well as improving stool consistency.

Now that you know what I regard as the best alternative, let me go on to share two more options, as well as some things to look out for before you commit to buy any other alternative.

In this section, I will share with you three alternatives to Peridale Granules that you can consider.

  • It helps to improve digestive function.
  • It helps with constipation.
  • Can be mixed with food easily.
  • Helps anal gland problems.
  • Improves stool consistency.


  • It may not work for all cats.

What I appreciate about this Pro Fibre Supplement

Anyone with a cat that has issues with constipation or digestive function will agree, it’s not nice to deal with. Especially constipation affects their diet and it is a painful experience for them.

The good thing about Protexin is it can easily be mixed into your cat’s food if you are worried that she won’t like it. let’s face it what cat really likes any of these supplements? Exactly, none, it’s made to help them, not as a tasty treat, right? So, if you can easily mix it, it will help her to consume it.

For those cats that have issues with their anal glands, resulting in stool problems, this will help to bulk up the stool for your kitty.

What I am not loving about this Supplement

Like everything in life, nothing is completely perfect. In fact, let’s be honest, absolutely nothing is perfect, right. And, this supplement is no exception. The only real issue I have with this supplement is, for some reason there may be some cats that it will not work for.

In some cases, it’s the owner’s fault for not following the directions. Or, just generally doesn’t get on with that particular cat. But, it’s worth a try to see if can work for you.

02. Glandex Cat Fiber Supplement

  • Helps anal gland issues
  • Guaranteed results
  • Recommended by vets
  • Natural ingredients


  • Some cats may not love the flavor

What I appreciate about this Glandex Supplement

The Glandex supplement is another great option for your cat. It also helps with cats that have anal gland issues. It does this by helping with inflammation in that area. As well as making the stool firmer.

One of the things I like about this product is the bold guarantee that the vendor makes. They offer a guarantee if you do not see any results in up to five weeks. They make this claim because they are confident that their customers will love the results.

Not sure about you, but, this kind of claim is not usually made easily. And, it is a good indication of confidence in their product.

Then there is the fact that they claim that this product is recommended by vets. In all honesty, I can’t be sure how solid this is, but, for them to make this claim, they must feel confident, are you with me?

Finally, it is claimed to include natural ingredients.  This includes pumpkin seeds & probiotics.

What I am not loving about this Supplement

Judging by some of the reactions, not all cats will love the flavor of this. I understand that every cat is different, some will love it, others will not. For these cats, you can try and mix it with their food to see if it makes a difference.

03. Stewart Fiber Formula

  • Distributed by vets
  • Helps with Urinary Tract Infections
  • Helps with hairball issues
  • Helps with megacolon issues
  • Great for cats that hate traditional powdered supplements
  • Can be crumbled


  • Quite a hard texture.
  • Small quantity.

What I appreciate about this Stewart Supplement

The vendor claims this Stewart supplement is offered by vets, which is a great endorsement and helps me feel comfortable as an option. It can help with several health issues such as Urinary tract, hairballs, and megacolon issues.

Some cats just do not like the conventional powdered supplements. That’s where these come in handy because they are like little biscuits, most cats will receive them as a type of treat. Which makes them perfect for those cats that are picky. You know, those really finicky cats that refuse the most popular food options, are you with me?

Another thing that I like about this is the fact that they can be crumbled down for cats that prefer a finer, grain-like texture.

What I do not like about this Supplement by Stewart

The main gripes I have with this supplement is the fact that they are quite hard. For this reason, some cats may not like them. And, finally, the quantity. I was hoping there would be more in the packet, to be honest. This could easily be an area for improvement.
