Our pick of the best cat food for constipation:

How can I tell if my cat is constipated?


If your cat is constipated it will display symptoms. In some cases your cat might only have one or two of the symptoms, in more severe cases your cat might display all the symptoms we list. Keep an eye open for the following symptoms of constipation in your cat :

Reduction in frequency 


Your cat should be passing stools at least once per day. If your cat doesn’t pass a stool for 48 hours, then a visit to the vet is necessary. At the 48 hour stage, your cat might be impacted so badly that nothing you do will get their system moving. This level of blockage may start putting a strain on the internal organs of your cat and may need manual unblocking by the vet!

Straining


If your cat is straining and appears to be in some discomfort when they are in the litter tray then this is a bad sign that they may be suffering from constipation. 

Stool Consistency


Check the consistency of your cat’s stools. If they are hard and dry this may indicate that they are suffering from some constipation. The amount of stool is not so much of a factor as this can be dependent on the digestibility of the food in the diet. The more digestible the smaller the output of stools.

Blood and mucus in the litter box


If there are traces of blood and mucus in the litter tray or with or without hard, dry stools then the chances are your cat is constipated and having problems. 

Vomiting 


If your cat is vomiting it could be because its digestive system has ground to a halt due to constipation and the digestive system is rejecting additional material in an effort to clear the blocked system. Vomiting could be a side effect of constipation but could also indicate other health issues.

Loss of appetite


As with vomiting, a loss of appetite could occur if your cat has constipation so bad that the digestive system grinds to a halt. Either way, a loss of appetite, vomiting and a cat that doesn’t pass stools for 48 hours should be a very big clue that your cat needs medical attention!

Frequent visits to the litter box


If your cat is making frequent visits to the litter box without anything happening then that is a big clue that they are having issues. It is likely that your cat will also be straining at the litterbox. If you take your cat to the vet at this point they are likely to ask when the last time you saw the cat pass a stool, whether any blood or mucus was present and carry out a physical exam to ensure the bladder is empty so they can confirm constipation.

Defecating outside the litter box


If your cat is defecating outside the litter box they are trying to communicate with you. If the litter is fresh and you haven’t changed the litter brand or type recently you should get suspicious. If the stool is hard and dry then constipation is likely the issue they are trying to communicate to you. 

If the litter is well used they might just be uncomfortable about using it. If you have changed brand or type recently it might be uncomfortable on their paws or the new litter might be a material they do not associate as suitable for use in the litter box.

What are the causes of constipation?


So you think your cat might have some level of constipation and are wondering how they got into this state when you take really good care of them? There are a number of potential causes and on the whole, they are down to plain bad luck rather than poor owner behavior:

Dehydration


A lack of water intake or increased water loss (vomiting, hyperthyroidism) that leads to a state of dehydration is a common culprit when it comes to constipation in cats. Cats don’t suffer from thirst as badly as other mammals which are believed to be a throwback to their origins as desert dwellers. This means your cat can easily get low on water without noticing. Many owners feed their cat’s dry diets these days for convenience. These dry diets might only contain 20% moisture whereas a wet, canned cat food can contain as much as 85% moisture. In these conditions, it is easy to see how a cat on a dry diet might become dehydrated leading to constipation.

Lack of fiber


In a natural diet, a cat would be eating fur, ligaments and small bones that would be indigestible and would bulk up the material in the digestive system. This bulked up material would help the gut maintain motility and aid the passage of stools. In a modern, man-made diet, your cat needs fiber to replicate this activity.

It might be that the food you are feeding your cat doesn’t have enough fiber – you might have been convinced to put your cat on a low carb diet thinking this was more natural and overlooked the fiber situation. A lack of fiber in the diet is likely to contribute to constipation.

Obesity/lack of exercise


Cats who are obese are known to suffer from constipation more than active cats that are at a healthy weight. Exercise and physical movement can increase gut motility. Inactive cats miss out on this stimulation and can develop constipation as a result.

Physical blockage


Your cat can develop constipation as a result of a physical blockage. The blockage might be a hairball, tumor or even compacted waste that has been unable to transit the gut. Constipation in long-haired cats is particularly common and is often due to hairball issues. 

Nerve Damage


If your cat has had a fall, been hit by a vehicle, or suffered nerve damage by other means this could result in constipation. Anything that might affect the transit time down the GI tract can result in constipation as things grind to a halt. 

Arthritis/Painful Defecation


If your cat finds using the litter box painful in some way or suffers pain trying to use the litter box it may delay using the litter box and become constipated as a result of delaying defecation. Sore joints caused by arthritis or issues such as polyps, fistula or anal tears might all contribute to a situation where your cat finds it too hard or painful to defecate leading to constipation.

Dirty Litter Box


A dirty litter box is enough to prevent some cats from defecating. Generally, in this situation, they won’t defecate elsewhere and will hold on until the box is clean enough to use. This period of holding on can lead to constipation. 

A related but slightly different situation is where you change the brand or type of litter and confuse the cat or the cat finds the new litter off-putting in some way. They might refuse to use the litter due to uncomfortable sensations on their paws, different odor or unfamiliar textures. The result is that they hold on too long and cause constipation.

Stress In The Home


The stress might come as a result of being in a multi-cat or animal household and not having secure access to the litter tray, from household invasion from other cats in the neighborhood, from incorrect positioning of the litter tray in the home or any number of potential off-putting issues. 

To avoid such stresses have more than one litter tray in the home, put them in quiet ambush free areas, never place them close to food or water sources and make sure there is good access at all times. Any situation that might slow down or prevent your cat from using a litter tray or defecating can give rise to constipation.

Megacolon


Cats with a condition called megacolon often run into issues with constipation. In the majority of cases, the cause of megacolon is unknown. Megacolon is a condition where the colon becomes extended and loses motility meaning nothing gets passed through. It is treated by careful diet management, medicines and in some cases surgery. If your cat is constipated on a regular basis your vet will investigate and look to rule out megacolon as a cause.

How Can I Treat Constipation?


If your cat is seriously constipated or has not defecated for 48 hours it is best to visit a vet and make sure there are no underlying issues or causes – your cat may need rehydrating by iv solution or monitoring over a longer duration. 

If your cat is in good health and you are concerned about the possibility of constipation or suspect they may have a very mild case of constipation you can treat constipation in your cat at home. Here are some tactics you can employ :

Home remedies

Increase Water Consumption


If your cat is passing hard, dry stools or seems to be less regular the first thing you should do is try to get more water into them. This is easier than it sounds, but the most straightforward method is to get them on a wet diet as soon as possible as this will deliver a significant amount of moisture into their diet. 

Other tactics to get them to drink more water include moving the water away from food – drinking water near food is instinctively wrong as they fear water contamination from food. You can also try increasing the number of water points around the home and getting a cat water fountain to give them running water to drink.

Increase Play/Exercise To Get Things Moving


Physical movement can stimulate your cat’s digestive system to become more motile. Get them playing and exercising to try and loosen things up! An added bonus of this exercise is that it should help keep weight off your cat – obesity is a risk factor for constipation. 

If your cat is an indoor cat try to make time every day for a period of exercise. The exercise should really get them moving and leave them panting looking to rest on occasion. Less exertive exercise is useful for keeping them mentally stimulated but you want them running and jumping to get things moving and keep the weight off. Laser pointers for cats are really useful for getting your cat running!

Canned Pumpkin


A small dose of unsweetened canned pumpkin can be a good source of fiber that can get your cat moving. You only need about a tablespoon mixed in a day’s supply of cat food to help keep your cat moving. Of that tablespoon 90% is water and 2.8% is fiber so you get a useful laxative effect!

Supplements

Laxatone 


Laxatone is an over the counter laxative that you can get for cats or dogs. It is primarily marketed as an aid for lubricating the digestive tract with a view to excreting hairballs and the like. The gel comes in a tuna or malt flavor so is easy to administer to your cat and can help as a preventative to constipation or if your cat is prone to hairballs

Metamucil 


Metamucil is a fiber source you can add to food. Metamucil is created from psyllium – a well-known source of fiber – and is added to cat food in portions of 1-4 teaspoons per meal. It is available in various forms but for a cat, you need an unsweetened and unflavored form.

Miralax


Miralax is a laxative and stool softener that is available over the counter. Needless to say, this can help your cat defecate if they appear to have problems or are producing hard, dry stools. The recommended dosage is a quarter of a teaspoon per day.

Cat Food 


You can help your cat avoid constipation in the longer term by picking a cat food that with help avoid constipation. Ideally, you want to look for moisture-rich cat food (wet) with fiber and highly digestible ingredients. 

Highly digestible ingredients reduce overall stool output as most are digested, improve GI motility and reduce potential inflammation in the digestive system. Ingredients that are high quality tend to be more digestible, think animal proteins and fats, carbs should be minimal although some fiber which is a carb is necessary to replicate fur and bones in a natural diet.  

Check out some of these highly digestible cat foods for reducing constipation:
