The 5 Best Cat Foods for Constipation

A gray, tan-ish, and white tabby cat is lying in an enclosed litter box, with its head resting on the edge.

Before having a cat, you probably didn’t realize how much of your time would be centered around their bathroom habits. There’s the daily scooping of the litter box and the occasional accident, but you can also tell a lot about a cat’s health through their feces, or lack thereof.

One of the problems cats can face is constipation, the reduced or difficult passage of feces. Constipation can also indicate that something worse is brewing with your cat’s digestive tract or other systems. It can also be something that plagues some kitties throughout their life. For those cats, finding one of the best cat foods for constipation may help them with this ailment.

  • Best Cat Foods for Constipation Buying Guide

There are many reasons that a cat can become constipated. Anything from eating something they shouldn’t have to the side effects of a medication can leave your kitty a little stopped up. Fortunately, feeding them the right food can help set things right again, but you’ve got to know what makes that food the right one.

Signs of Constipation in Cats

Most kitties keep a fairly regular schedule, even for pooping. So, if you find an empty litter box after a couple of days, your cat may be constipated. However, just because there is feces in the litter box doesn’t mean that your cat is home-free. Small, hard pellets rather than regular, formed, moist stools are also a sign of constipation.

Some cats may show their constipation by their discomfort. Cats that cry or strain when at the litter box may be having some digestive issues. Also, cats that avoid the litter box altogether may be suffering as well. Litter box aside, constipated cats may also not be eating as much, not want to jump or play, may walk stiffly, or may hide.

Why Do Cats Get Constipated?

Causes of constipation in cats can be as simple as dehydration caused by not drinking enough water. Hairballs or ingestion of foreign bodies like string or bone can cause blockages in the intestines. Lack of exercise slows the movement in the digestive tract, and pain in the pelvis or legs from an injury or arthritis can keep a cat from trying to defecate.

More serious causes include kidney disease, nerve dysfunction, megacolon, hyperthyroidism, inflammatory bowel disease, diabetes, anal gland problems, and some kinds of cancer. These issues can lead to constipation due to decreased movement of the intestines, pain, or dehydration.

What to Look for in Cat Foods for Constipation

As long as your cat doesn’t have any underlying health conditions contributing to their difficult bowel movements, giving them the right cat foods can help keep them regular.

Proper foods include:

  • Fiber:  Fiber comes in two forms: soluble and insoluble. Soluble fiber dissolves in water while insoluble fiber does not. Both promote regular digestion from different angles, so they work together well when combating constipation. Soluble fiber from pumpkin, apples, or psyllium is fermented into volatile fatty acids in the colon, which helps to stimulate intestinal contraction. Insoluble fiber from green beans, nuts, or wheat helps bulk up a bowel movement to stimulate those same contractions. The result is the same, a more motile colon to move feces through and out.
  • Moisture:  One of the colon’s main jobs is to absorb water. This means that the longer a bowel movement sits in the colon, the more water that gets sucked out of it and the harder, drier, and more difficult to pass it becomes. Along with this, dehydration is one of the leading causes of constipation. Increasing the amount of moisture in the food to increase the moisture in your cat’s feces can help overcome this problem.
  • Probiotics: The primary regulator of your cat’s digestive tract is their microbiome. These are the good bacteria that digest food and get the nutrients where they need to go. Any disruption to the microbiome can lead to digestive upset, including constipation. Feeding a cat food rich in probiotics can help repopulate and support those good bacteria for a healthier digestive tract and less constipation.
  • Whole Foods: A cat’s digestive tract is acutely honed to digest prey. That’s their natural diet, and their guts are efficient at digesting it. They’re not meant to eat foods that have been highly processed or are full of artificial ingredients. Choosing a cat food made from whole foods, especially whole lean meats, is an important part of preventing constipation due to the digestibility of the food. Look for products that use whole meats as the first few ingredients and stay away from processed products like meals and flours.

Final Thoughts

Cats are no strangers to constipation, especially if they’re not on the proper diet. Giving your cat the right food for constipation can help put their digestive system on the right track. Any of them will supply the best nutrition with some additional bonuses to help keep their tummies full and their bowels regular.
