Constipation is a very common problem for cats. Often the symptoms are mild, and there are lots of things you can do at home to help your cat and ease their discomfort. Most cats pass feces every 24–36 hours, but if your cat is going less frequently than this or they seem uncomfortable when in their litter tray, they may well be constipated.

When your cat is constipated, feces get stuck in the large intestine for longer than usual, so it becomes dry and hard which exacerbates the issue and makes it even more difficult to pass. There are many different causes of constipation, some are mild and others are the results of serious health issues such as megacolon or kidney disease. These are complicated medical problems and home remedies are not appropriate here.

However, if your cat has mild constipation, you have come to the right place! Keep reading this vet-written guide to find out 12 natural home remedies for cat constipation.

Signs of Constipation

Constipation can vary greatly in severity. Some cats may have mild signs, while others can suffer a lot and be extremely uncomfortable.

The usual signs of constipation include (but are not limited to) the following:

  • Straining in litter tray
  • Difficulty passing feces
  • Pain when passing feces
  • Passing feces less frequently
  • Producing small, hard, dry feces

Constipation is usually easy to spot, and here is a list of some natural home remedies you can try if you see the early signs of constipation:

The 12 Vet-Approved Natural Home Remedies for Cat Constipation

1. Keep Your Cat Well Hydrated

If your cat is dehydrated, this will exacerbate their constipation. Keeping up fluid intake is the first port of call when managing constipated cats. This can be done in a number of different ways. You can leave water bowls around the house in easily accessible places as this will encourage the consumption of more water. Some cats enjoy using water fountains, or a dripping tap. You can also flavor your cat’s water with something strong smelling such as tuna juice or bone broth.

If you do this, ensure you leave some plain water out too. This is in case they don’t like the flavoring and need an alternative source.

2. Feed Canned Wet Food

Changing your cat’s food from dry to canned wet food can increase water intake, especially if your cat doesn’t drink much. Dry food does have some advantages, for example, it can aid in the mechanical debridement of your cat’s teeth. However, if your cat has issues with constipation, they should be taking in more fluids as there are other ways to keep their teeth clean.

3. Change Your Cat’s Diet

If your cat has a sensitive stomach or if they have allergies, this can cause inflammatory changes in the intestines that can lead to constipation. You can start by either changing the main protein source of your cat’s diet or feeding them a hypoallergenic diet. If your cat is reacting to something in their diet, feeding them something they don’t react to will reduce the inflammation. This facilitates normal peristalsis movements which means there is a reduction in the chances of constipation developing.

Increasing fiber in your cat’s diet will also aid with the movement of food through your cat’s digestive tract—more on this below. Speak to your vet about diets and supplements before making any dramatic changes.

4. Keep Your Cat at a Healthy Weight

Obesity is another thing that can cause intestinal inflammation, as it can slow the transit time of the digested food. This allows for too much water to be absorbed and causes constipation. If your cat is severely overweight, another factor is the physical weight of the fat around the stomach. It can slow the movement of food through the intestines just by the sheer mass present. If you need help or advice on weight loss for your cat, consult your vet.

5. Reduce Stress and Anxiety

Stress and anxiety can affect food transit time through your cat’s intestines.

Cats can become easily stressed by lots of different things. Changes in their environment, a new human or animal in their home, illness, changes in your routine, or strange noises can all cause unwanted stress and anxiety. To attempt to reduce this, you can make everything as consistent as possible.

If changes can’t be avoided, try to introduce them gradually. Some cats respond to products such as calming pheromones or anti-anxiety medication.

6. Provide Multiple Litter Trays

Cats are very sensitive about when and where they use their litter box. If they are not happy with something, this can put them off using it altogether, which can cause constipation and urination issues too.

Cats may be put off by other cats using a litter tray. It may be an incorrect size so they don’t fit in, they may feel exposed if there is no cover on it, or there may not be enough litter in it. It may also be in a loud and busy location. It can be a case of trial and error finding a tray and location that your cat is happy with, but it is definitely an important factor in healthy bowel movements for your cat.

7. Ensure Your Cat is Getting Enough Exercise

Much the same as humans, cats benefit hugely from exercise. If they lead a sedentary lifestyle, they are less likely to have healthy peristalsis movements. A reduction or loss of these movements can result in constipation. If they are lying in one position for long periods, it will be more difficult for them to digest their food properly.

You can encourage your cat to be more active by using cat toys and playing with them. Enrichment objects are widely available for your home such as cat trees and scratch posts. It is likely if they are more active and have mental stimulation for the duration of their day, that they will be less stressed and anxious and less likely to be overweight.

8. Increase Dietary Fiber

Feeding your cat a higher proportion of roughage can help food pass more easily through their gut. Fiber also helps retain water in the intestines. There are a few different types of fiber commonly used in cats, and these include psyllium husk and wheat bran. Not all cats with constipation benefit from a high-fiber diet as it does depend on the underlying cause, so always speak to your vet before adding anything to your cat’s diet.

9. Over the Counter Laxatives

Some over-the-counter products can be used to help your constipated cats at home, however, never use any medication at home without first consulting your vet. Laxatives usually work by drawing more water into the intestines, helping to soften the feces, which aids in the cat passing them. This can be dangerous for cats with other health issues so use with caution only under vet instruction. Some laxatives can affect your cat’s ability to absorb nutrients from their food if used long-term, so it is always best to check with your vet first.

10. Probiotic Supplements

Some brands of cat food contain probiotics already. If this is not the case, you can buy probiotic supplements specifically for your cat. Probiotics can aid in the relief of constipation, and they also help maintain good digestive health.

11. Brush Your Cat Regularly

Hairballs are a very common cause of constipation in cats. If you brush your cat regularly you are removing excess hairs or hairs that are ready to shed. This means when your cat grooms itself, it won’t be accidentally swallowing lots of hairs that will contribute to hairballs. If you know your cat has problems with hairballs, there are also over-the-counter products you can buy to aid in the passing of hairballs.

12.  Keep Your Cat’s Backend Clean

Regularly check the area around your cat’s backside to see if it is clean and free of clumped hair or dried feces. It sounds like a simple thing, but if there is matted hair and dried feces stuck to this area, it can be very painful and can certainly put your cat off trying to pass feces. This is especially important if your cat has long hair as it is more likely to get knotted and matted. It is good practice to check and clean this area so that your cat is used to you having a quick look to ensure it stays hygienic.

Often, cats struggle to clean this area if they are overweight so this is another reason to keep your cat in trim condition. Cats with arthritis may also struggle to clean this area, so be aware they may need a little help.
