What is cat fiber supplement? 

Before knowing about cat fiber supplement, we should know what exactly fiber is? Fiber is a kind of carbohydrate that’s typically sourced from vegetables, fruits, nuts, berries, and other components of plant origin. Fiber can also be sourced from animal-based components such as bones, fur, or even cartilage. So do cats need fiber and is it important to the cats’ health?

The answer is yes! But cats are carnivorous so how can they get fiber into their diet? It really comes down to the lifestyle of the cats and their general health. Outdoor cats can get fiber from animals that they hunt and eat but indoor cats do not have this opportunity.

That is the reason why we need cat fiber supplements to add fiber into their diet. Cat food with fiber is usually a combination of water-soluble and insoluble fibers. Some ingredients used to manufacture fiber are also referred to as prebiotics. These ingredients are typically fermentable fibers that support the development of the “good bacteria” that are useful in the cats’ intestines.”

Why is fiber important for cats? 

There is no doubt that fiber is an essential element of the human diet. Eating enough fiber is important for a healthy digestive tract and overall wellness. It can help us prevent or relieve constipation, controls blood pressure, and can even regulate blood sugar levels.

But how about cats? It’s known that there is no requirement for fiber in cats’ diets but fiber has the same useful properties for cats as for humans. This is a carbohydrate that cannot be fully digested by our intestinal systems. Hence, it goes all the way through the intestine and cleanses the bowels. It can help solve cats’ health issues such as diarrhea, fatty blood, constipation, or even diabetes and also help them have a healthy weight.

What are the important features to consider the best cat fiber supplement?

We all know fiber is good for cats but do you know how much fiber the cats need? and which one is the right kind of fiber needed for your fuzzy friend’s health. As a cat parent, you should understand your cat’s health to choose the right food for them. How much fiber do the food should contain if your cat has Gastrointestinal Issues, or it has Diabetes or even your cat is overweight? This is the reason why the most important thing you should keep in mind when you’re looking for cat fiber supplement is your cats’ health condition.

Fiber is mainly divided into 2 types:

  • Insoluble fiber also can be known as crude fiber does not mix with the liquid and passes through the digestive system without being broken. It is not a good fiber but it can be used to help food and waste pass through the digestive system easier and quicker.
  • Unlike insoluble fiber, soluble fiber can be blended in water, forming as a substance like gel. It helps scale back glucose in blood and to provide a variety in benefits for health.

As mentioned before, fiber is good for a cat’s health but depending on its own condition to choose the right cat fiber supplement with the correct amount will be better for their health.
