What Is Cat Constipation?

When a cat is constipated, he or she cannot defecate according to his/her routine.

Your cat may be defecating every other day or longer. If your cat successfully eliminates his or her bowel, he or she may produce hard and dry feces in the litter box.

According to Cornell University’s College of Veterinary Medicine,  your cat should poop at least once a day to detoxify his/her body.

If your cat doesn’t remove the unnecessary elements in his/her body for a long time, they would build up and enlarge the colons in a short time.

An enlarged colon could bring a whole slew of problems and could even result in surgical treatment if the condition worsens.

Why Is My Cat Unable To Poop?

The first and most common primary suspect for this is dehydration.

Since your cat doesn’t drink much water, the colon absorbs water from the food waste in his/her large intestine, making the cat litter dry and harder to eliminate.

This is especially common if you’re feeding your cat with more kibbles than canned food. During their primitive days, a cat’s prey is their best source of fluid. Now that their food and lifestyles have changed, canned foods with high moisture are their best sources of daily water needs.

Your cat might be stressed with his/her environment too. If s/he feels unsafe when using the litter box, s/he will avoid it as much as possible.

An obese cat, particularly an indoor cat, is more prone to constipation.

This is because indoor cats are not engaged in physical activities that much, so they can’t maintain peristalsis in their colon.

These are the rhythmic contractions of the muscles in their colon that help move the food waste through their GI tract. The lack of fiber in your cat’s food or diet may be the root cause too.

Cats don’t need much fiber since they’re strict carnivores, but the texture is still essential in a cat or kitten food to keep his/her GI tract healthy.

Sometimes, fur can also be a suspect. If your cat unconsciously swallows a lot of his/her hair while grooming, it can impede the movement of waste in his/her colon.

This could be traced to inadequate protein in their system.

Constipation Can Also Be A Minor Symptom Or Effect Of A More Serious Condition.

A cat with arthritis is also a candidate for this constipation. Because it’s painful for a senior cat to bend his/her knees while defecating, the automatic reaction would be to avoid pooping to avoid the pain.

If your cat has inflamed or ruptured anal sacs, s/he may experience a more difficult and painful defecating experience.

Think hemorrhoids in humans, and you’ll get the picture of how painful it is.

Megacolon is the most severe cause of this disruption of bowel routine.

In this condition, the colon of your cat stops functioning, so the food wastes are stuck here and enlarge the colon in the long run.

When not treated immediately, this difficulty can result in obstipation, the severe version of constipation. When this happens, your only option is surgery.

The Symptoms Of Constipation

How can you tell if your cat is having a difficult time in the litter box? Here are the signs you should watch out for:

  • A significant change in defecating routine – from daily to every other day or more
  • Your cat’s bowels look dry, and litter doesn’t stick
  • Loss of appetite during the past few days and the water bowl remains full at the end of the day
  • S/he looks stressed and strained while trying to defecate
  • Sometimes, a constipated cat defecates out of the litter box
  • Vomiting, which is a reflex associated with straining to eliminate bowels
  • A small amount of liquid in the feces, either mucus or blood

How To Palpate A Cat For Constipation?

You can do a quick evaluation of your cat to confirm if she’s constipated:

  • First, check the anus and see if it’s inflamed. If you notice dried feces sticking outside, and if it looks strained (like reddish muscles from trying hard to defecate), that’s one sign off the checklist.
  • Next, you can palpate the lower abdomen. If you “pinch” the lower part of the abdomen (the section of his/her belly near the tail), and it feels a bit harder or firm, that can also be a sign.

Note: If you’re going to try palpating your cat, best to do it slowly and gently. Pinching your cat abruptly may turn him/her aggressive.

What Ingredients In Cat Food Can Help The Defecating Routine Of My Cat Return To Normal?

When you go shopping for food supply for your cat, look for these ingredients on the label:

High In Fiber

Usually, a cat doesn’t need much fiber in its food. But for a constipated cat, fiber can serve as an excellent remedy for bowel problems and promote good gut health, according to Dr. Sa Depauw and his colleagues.

Fiber’s recommended to be consumed in small amounts only, so it’s best to check how much fiber is included in the cat food label.

Two types of fiber act as a remedy for your cat: soluble and insoluble fibers.

Soluble allows more fluid to retain in your colon, making the stools of your cat softer and easier to eliminate.

The latter adds bulk to the feces, allowing the wastes to move faster in the colon and avoid strained bowel movements.

Here are some great fiber sources commonly found in any cat food for constipation:

  • Pumpkin
  • Flaxseed
  • Dried kelp
  • Catnip
  • Cat grass
  • Chia seeds
  • Lentils
  • Green Beans


According to Dr. Debra Zoran, protein is discovered as one of the essential nutrients in a cat’s diet to prevent him/her from being constipated in the future and acquire other GI diseases.

This nutrient helps the waste in the colon of your cat move smoothly and also prevents hair buildup.

A cat food usually has chicken, turkey, lamb, beef, or venison as its protein source.

Moisture-rich Ingredients

Your cat needs water to keep his/her bowels moving smoothly. Wet cat food contains plenty of these ingredients, with most of them having 75% moisture.

Easy Home Remedies For Constipation In Cats

You can do the following natural home remedies to help your constipated cats poop. Some remedies can be mixed with the cat food of your choice:

Natural Home Remedy

  • Mix one – four teaspoons of Metamucil in your cat’s food, once or twice a day, to provide more fiber in your cat’s diet.
  • 1/4 teaspoons of Miralax mixed once a day in wet cat food can help soften the hard stools of your cat and make pooping easier.
  • You can also mix one to two tablespoons of wheat bran in your cat’s food once or twice a day.
  • Canned pure pumpkin is also one of the best options, although the fiber content isn’t as great as the three high fiber diet sources mentioned. Just mix a teaspoon once or twice a day on your cat’s food.
  • Added aloe vera juice in cat food can be an effective remedy too, but better ask your vet first before giving your kitty this (and other laxatives too).
  • If your cat has an issue with hairballs, you can also mix a non-petroleum hairball treatment or a teaspoon of coconut oil on his/her meal.

Additionally, you can also do the following to help your constipated cat defecate:

Help Your Cat Increase Their Daily Water Intake

Feed him/her more with wet canned food. Replace the water bowl or water fountain for your cat with a pet fountain, so it becomes more enticing to him/her.

Encourage Your Cat To Engage In More Physical Activities

Build playgrounds, give him/her more cat toys, and increase the playtime of your cat every day.

Help Your Cat With His Or Her Grooming Routine

Lessen the hairballs she unconsciously swallows while grooming.

When Should I See A Vet?

It’s best to seek medical expertise for your constipated cat if you’re in the following situations:

  • When you’ve exhausted all remedy options, and you don’t see any improvement (or worse, she’s getting sicker every day), it’s best to rush to your veterinarian.
  • If you’re feeling unsure or nervous about trying specific home remedies or cat food for your pet cat, your vet can give recommendations.
  • An obstruction in the colon is commonly confused with problems in the urinary tract because they share almost the same symptoms. If you aren’t sure which of these conditions are giving your cat difficulty, consult with your vet so you can determine the right treatment and cat food to provide.

Take Action Immediately When The Earliest Symptoms Of Constipation Appear.

If you see the symptoms mentioned in this guide, it’s a good idea to make a move and give your cat the best possible remedies.
