If you are considering home remedies for cat constipation, there's a good chance your moggy is having a problem pooping. In fact, it's an identical issue to constipation in humans, meaning bowel movements become less frequent than normal and passing stools is more difficult.

One thing's for sure, you need to offer your cat assistance. Since felines will try to force their poop out of their bodies, it will inevitably lead to abdominal pain. Of course, having a build up of feces inside the colon, which is what happens in this instance, is undesirable in itself. But what are the signs of cat poop problems and what can you do?

Cat constipation symptoms

Being able to spot the signs of constipation in cats depends on the type of moggy you have. If your cat goes outside to poop then you may not know that your feline has a problem for a while – you're going to see the issue much more clearly among indoor cats.

Indeed, if you check a cat's litter tray and it appears to be empty for more than 24 hours, it's time to be on the alert. At this stage, look out for signs of a tense abdomen, a hunched posture and a decreased appetite or maybe even vomiting. Cats can also become more lethargic when they are constipated and, if they are passing any stools, they are likely to be small, hard and dry.

Sometimes you end up seeing fecal fluid and it can look as if they are suffering from diarrhea. In all likelihood, this is going to be due to irritation of the colon lining, causing fluid to leak out of the cat's bottom. If you spot any signs such as these, then it's time to take some action. You may not necessarily have to visit a vet just yet – duration and severity are good indicators.

Causes of cat constipation

In humans, constipation is usually caused by diet: a lack of fluids, fiber or a sudden change are generally to blame. We can also get constipation if we sit or lie around for too long or exercise less than we should. Holding poop or becoming stressed or depressed are causes too.

Cats generally suffer constipation for much the same reasons. They may be reluctant to poop and hold it in for much longer than they should, for example. This could be due to a dirty litter box or its position: cats are clean creatures and they can also become stressed and anxious if other cats are around or if the environment is not quite to their liking, perhaps because it's too busy and noisy. 

You should also be aware of what a cat is consuming. A lack of fluid or a diet with insufficient fiber are likely to cause a problem. There are, however, other serious causes of constipation such as arthritis, allergies, inflammatory bowel disease, a hernia or a tumor around the pelvic area, cancer, perianal disease or an obstruction of the colon.

Indeed, the condition tends to arise more in older cats although this could be generally down to a more sedentary lifestyle. Finally, watch out for over-grooming: the more a cat licks their fur, the more hair is likely to make its way into the digestive tract and cause problems.

How to help a cat poop when constipated

If you believe your cat is constipated then you're going to want to do something to help. The good news is that there are a number of home remedies which can work wonders but, if you're going to try to offer assistance rather than call the vet at this stage, keep an overview of your treatment plan to ensure that it's having a positive effect.

You can do this by keeping a diary and noting down any symptoms you spot each day. It's a good idea, if the issue relates to an outdoor cat, to try and keep them indoors and introduce them to a litter tray so that you can monitor the stools for consistency and number. Keep a good idea on any potential displays of pain or strange behavior and check that they are eating.

But what home remedies can you try? Much depends on what you think the problem is but here are some suggestions:

1. Change the litter box

It's always a good idea to keep a litter box clean, more so if you're worried that it could be causing cats to hold their poop. A quick fix here is to ensure your cat's litter box is placed in a pleasant place. That way you can be sure that your cat at least feels comfortable trying to poop but if a feline already has constipation then this remedy is unlikely to resolve the issue in and of itself.

2. Add more fiber to the diet

You need to find a way of increasing the size and weight of a cat's stool and fiber does both of these things. It also softens feces making it easier to pass – aim for insoluble fiber and the stool will become bulkier thanks to the addition of moisture. Be wary of adding more fiber if your cat is already getting a lot, though. In this case, it could make the problem worse and you need your cat to digest nutrients.

3. Change the protein

It's also worth thinking about altering the protein source of a cat's diet, switching from lamb to chicken maybe but be aware that a change such as this can take anywhere from two to three months to have an effect. 

It's not going to prove effective if the problem is a pressing one that needs immediate action. This is something to consider once the current issue has been resolved. Be sure you know how to transition cat food safely if you are considering this. 

4. Reduce anxiety and stress

There could be an underlying environmental cause for constipation. Is your cat going outside and getting bullied by other cats, for instance? Or is your family life too hectic for your kitty at the moment? Maybe a dog has moved into the neighborhood or someone is having an extension built. Giving supplements such as Zylkene and Solliquin or a calming pheromone such as Feliway can work wonders.

5. Offer them water

Cats don't tend to like licking water out of a bowl so if you want to make sure your feline friend is getting enough moisture then you have to think a bit more creatively. Maybe invest in a water fountain for your pet – the sound and smell of the water is enticing. 

You should also consider the best cat food for your feline friend with constipation: reducing the amount of dry cat food you give in favor of the best wet cat food can increase moisture intake. 

6. Keep them busy

Active cats are less likely to become constipated because it helps the intestines to move normally. Since taking a cat for a walk is out of the question (for most felines anyway!), you need to exercise a cat and keep them both mentally and physically stimulated by playing with them. Take your pick of the best cat toys and consider the best automated cat toys if you're away a lot.

7. Ensure a healthy weight

An obese moggy is undesirable for a number of reasons and the risk of constipation is one of them. Inflammation in the intestines means feces tends to hang around for longer as if attempting to make its way through your cat's body. Cutting a cat's weight if they are deemed to have packed on the pounds will help in the medium-to-long term and help to head off future problems.

When to see the vet 

According to vet Rebecca MacMillan, who has provided an in-depth guide to normal vs abnormal cat poop in our vet's guide, it's usually a good idea to get a cat checked out if you suspect constipation. 

Certainly, if the remedies above are not working very quickly, then you need to be sure that there are no underlying conditions such as a tumor, growth, nerve disorder, hernia or trauma to the pelvis. Vets are always there to advise and they can also offer over-the-counter laxatives which adds extra moisture to the intestines to soften the stool. These should not be used without vet advice, however.
