Best Cat Food For Constipation: Top Wet and Dry Picks for 2020

Amongst the most common health problems in cats, constipation happens to be one of the most frequent ones and is caused by a myriad of reasons. Before we provide our top choices for the best cat food for constipation, let’s talk about the issue itself and what causes it in the first place. 

As in humans, constipation is caused by blockages in the gastrointestinal tract (GI) which leads to infrequent bowel movements which can be very unpleasant and right out dangerous for the health of your cat. When you notice that your cat has not had a bowel movement for longer than 36 hours you should begin paying closer attention. This can be a beginning of problems with your cat’s GI, considering that a normal frequency for cats is to go at least once every 24-48 hours. 

What Causes Constipation in Cats

There are many reasons why your cat might be experiencing constipation, however, the ones outlined below are the most common ones. Once you know why your cat is constipated, you can prevent it from happening again, or at least decrease the chances. 


According to PetMD, cats can become dehydrated for various reasons, therefore in order to help them you might need to adjust their diet from dry to canned food and make sure that he/she always has access to water. Sometimes you might need to change the way your pet intakes water and to allow access to a proper water fountain, as some cats prefer running water as opposed to stale.

Fibre Poor Diet

Fiber feeds the good bacteria and helps promote normal movement in the intestines. It can also help keep more water in the intestines, which helps treat and prevent constipation. If your cat is not consuming enough of fibre, it can lead to constipation.

Ingesting Foreign Objects or Fur Balls

Considering the love for self-cleaning in cats, sometimes overdoing it can lead to excessive amounts of hair in the system which in return can lead to blockages in the digestive system and result in constipation.  

If your cat swallows a piece of clothing or a string this can too lead to a blockage of the small intestine and colon. 

Anxiety or Stress

If a cat’s routine is compromised they can get easily stressed and experience health concerns such as constipation. Examples could be a move to a new house, new dog barking in the neighborhood, an addition of a new pet to the household, and many others. Sometimes it will take a certain amount of time for a cat to adjust and the problem will go away, but you might need to experiment with calming pheromones, supplements, herbs or medication to speed the process along. 

Litter Boxes

The most basic change you can make to help your feline friends is to ensure they have access to clean and comfortable litter boxes at all times. Cats could protest a dirty and unkept litter box by not defecating. For that not to happen, ensure that the litter box is cleaned on a consistent basis. You can also offer them more than one option if you live in the house (you might need to put one on each floor of the house), and experiment with different types of boxes and litter to find what suits your cat. 

More Potential Reasons

If the issue isn’t one of those listed already, it could be a whole variety of other potential causes such as neurological or physiological damages, obesity, side effects of medication, tumors and hernia are some of the common ones. 

Some of the Common Signs That Your Little Furry Friend is Constipated

Challenging and Strenuous Defecation: 

If you see your car struggling to poop small amounts out or nothing at all it could be the first sign. This should never be a strenuous activity and if you hear your cat crying out in pain while trying to go, you can be sure that something is wrong. 

Hard and Dry Stool:

The usual stool is brown and somewhat moist, however, if you see dark, dry and very hard stool, this can also be a sign that your cat is constipated. It could also be covered in mucous or blood, and be much smaller than usual. 

Loss of Appetite: 

A cat with constipation issues is likely to avoid food due to stomach and intestine discomforts that car range from mild to severe. 

Several other symptoms of constipation are:

  • excessive laziness and lethargy
  • weight loss
  • vomiting and nausea
  • difficulty jumping 
  • walking stiffly

Considering several of these symptoms could be signs of other health issues, advice from a veterinarian is always advisable.

 Instinct Original Grain-Free Pate

 Instinct Original Grain-Free Pate Review

Why we like the Instinct brand is because the company’s philosophy stands for making food that matches animals original evolutionary diets as closely as possible. Sticking on the subject of cats, and them being natural carnivores, having raw meat diets has been a norm for ages (hunting mice for example), and the Instinct products deliver just that. 

The company’s five Golden Rules are: Lead with raw, Keep it real, Make it simple, Do it together, and Make it better.

Besides real meat, which is by far a major ingredient, there are added fruits and vegetables for a complete and balanced meal. It also contains guaranteed levels of natural omega fatty acids for healthy skin and coat, probiotics for digestion, and antioxidants for immunity. This formula contains no grain, potatoes, corn, wheat, soy, by-product meal, artificial colors, or preservatives, making it one of the best cat food for constipation. 

The only drawback that we were able to find is that this cat food is not made for cats with hyperthyroidism.
