What Is Low Residue Cat Food?

Low residue cat food is a specialized type of food that helps in alleviating constipation in cats.

Similar to humans, constipation in cats is caused by the abnormal buildup of feces in the cat’s intestine. This can be rather painful and problematic for your cat.

Low residue cat food is characterized by being highly digestible and causes the least trouble among food types.

How to Tell That Your Cat is Constipated?

When cats are constipated, they start to show visible symptoms and signs that aren’t easy to miss. However, you need to make sure that they’re suffering from constipation before starting to change their diet and force them to drink more.

Here are some of the most common symptoms that a cat shows while being constipated.

The Litterbox is Noticeably Empty

It goes without saying that you’ll notice that the cat isn’t visiting the litter box as much. To call it constipation, a cat needs to go for about 48 hours without pooping. On the other hand, a healthy cat is able to defecate more than once a day.

You’ll also notice that your cat might poop outside the litterbox, which is one of the most obvious signs that something is wrong with your cat.

The Stool Shape is Different

Even if the cat managed to pass the stool out, it’ll look quite different. Normally, a healthy cat’s poop is usually a bit soft but firm with a slight smell that’s not too pungent. You can easily notice that it’s moist because litter sticks to it.

On the other hand, constipated cat poop is much harder and smaller than a healthy one. Also, litter doesn’t stick to it, as it’s too dry, which is a sign of dehydration.

Other Visible Symptoms

A healthy cat doesn’t show visible signs of struggle while doing the business. On the other hand, a constipated cat will strain to pass stool out. In severe cases, the poor kitty might start crying while trying.

This can affect the cat’s psychological health. So, your cat might show some signs of depression, such as decreased water intake and appetite.

What Causes Constipation in Cats?

There’s a wide variety of reasons that can eventually lead to a constipated cat. Let’s have a quick look at them.

Low Fiber Intake

Fibers are extremely healthy food ingredients that are essential to keep the bowel system healthy.

However, many cats only eat raw diet without adding any vegetable content to their diet. This can cause serious constipation, especially when paired with low hydration.

Low Water Intake

This takes us to the second most popular reason for constipation for both humans and cats. Since cats have a low thirst drive, they can go for a long time without drinking. This can easily cause constipation for cats.

Changes to the Cat Habits

This includes getting a new litter box and replacing the old one immediately. Such a behavior can drive the cat to avoid defecating, which piles up the stool until it’s too difficult to pass.

Also, many cat parents noticed that placing the drinking bowl near the litter box discourages cats from drinking. That’s why you need to make sure that they’re far apart.

Ingredients to Look for While Shopping for a Low Residue Cat Food

Here are some of the most important dietary ingredients that you should check in low residue cat food.

Highly Digestive Ingredients

This includes high fibrous content, which is essential for enhancing bowel health and reducing the incidence of constipation.

Stool Softeners Ingredients

Some low residue cat food will also have some ingredients that help in keeping the stool soft for longer. This is a sugary syrup called “lactulose”, which holds more water in the stool.

There are also other ingredients such as sodium docusate, which is also a stool softener that your vet can prescribe along with the low residue cat food.

Healthy Doses of Other Ingredients

In addition to their ingredients, the food should have a healthy amount of proteins and fats.

A healthy cat diet should be at least 40% protein, so make sure it contains high-quality protein to meet the healthy daily intake.


What is the right amount of fiber that a cat needs daily?

A healthy cat’s diet should contain fibers. Ideally, the right amount should be too much or too little.
In fact, quality fibers in healthy amounts can help in enhancing the cat’s bowel health by nourishing the natural bacteria in their digestive tract.
However, a low residue cat food must have a lower amount of fibers in general. Yet, it shouldn’t be without it altogether.
The lower fiber content helps in alleviating constipation. Once your cat is past the constipation problem, the fibers can be reintroduced to their diet once the vet gives you the green light.

What is Considered a Healthy Defcating Interval?

A normal healthy cat can poop daily and up to three times a day. Anything beyond that may count as mild diarrhea.
 On the other hand, a cat might go for as long as one or two days without pooping. However, anything beyond that is a cause for concern whether it’s accompanied by other symptoms or not.

Is constipation dangerous?

Constipation in itself isn’t a dangerous case and it’s easy to treat. However, the complications of leaving constipation untreated can be rather serious.
This complication is known as “obstipation”, in which the hard stool accumulates in the colon of the cat, causing hard stretching of the colon, also known as “megacolon”.
When this happens, the bacteria from the feces can get into the bloodstream, causing serious illness that can lead to death. So, in short, constipation itself isn’t dangerous and easily managed, but the complications are much more difficult to handle.

What if the cat stays constipated after adequate feeding and hydration?

In the majority of cases, maintaining a healthy diet with low residues with hydration and the right amount of fibers will solve the constipation problem in a few weeks.
However, if the problem persists, you need to pay a visit to the vet immediately, as this might be a case of intestinal or colon cancer.
