Constipation is a painful but common digestive problem for many cats. It occurs when the stool is too dry or too firm to expel, causing distress and pain for your pet. Healthy felines have daily and easy bowel movement, so if your kitty doesn’t use her litter box once a day, or if she does but it’s followed by crying and straining, it’s more than likely she suffers from constipation. If left untreated, constipation can lead to megacolon, a condition in which your pet’s colon is irreversibly stretched.
So how can you help your kitty become healthier? One, increase their water intake, and two, change their diet.

To help you find the best cat food for constipation more easily, we’ve done the research for you.

Is Your Cat Constipated?
Before you start feeding your cat a different diet or force her to drink more water than she’d like to, make sure she actually is constipated. Unsure how? Compare your kitty’s bathroom habits to a healthy cat’s bathroom habits:
- Healthy cats defecate once to three times a day, every day
- Healthy cats produce firm stools that keep their shape
- A healthy cat’s stool has enough moisture, so litter will stick to it
- Healthy cats easily defecate (do not strain).
Based on this, it should be easier to see if your pet is actually constipated or not. However, if you’re still not sure, the following symptoms of constipation should provide a definite answer:
- Decreased appetite and water intake
- Crying or straining while trying to defecate
- Small, dry, hard stools
- Not producing stools for 48 hours or longer.
Generally, a constipated cat will be in quite a bit of pain and you should notice the pet is acting differently than usual. This is because the longer the cat doesn’t defecate, the more gastrointestinal upset they’ll experience. And if these issues don’t resolve on their own (which they typically don’t), constipation can become obstipation. This is a severe form of constipation in which the cat cannot clear the mass of very dry and hard stools that have been accumulating in the colon. This, unfortunately, can lead to a complete blockage of the large intestine with feces which, in turn, can result in loss of the colon’s motility. Needless to say, you really don’t want to let your kitty’s mild constipation develop into something more serious.
Causes of Constipation in Cats
Now that you know whether or not your cat is constipated (still unsure? Get your kitty to a vet!), you’re probably wondering what causes this condition in the first place. Unsurprisingly, there can be various reasons for cat constipation, including ingestion of foreign objects, side effects of certain medications, traumatic injury, infection, intestinal tumors, even obesity. But the two most common causes remain dehydration and a low-fiber diet. Let’s talk about these two potential causes and what you can do to avoid them in the first place.
Like all living things, cats need water in order to survive. Unfortunately, many cats have a low thirst drive, which means they don’t feel the need to drink water that often. If your cat is one of these pets, here is what you can do:
- Make sure the cat always has fresh, clean water source available. Sometimes, larger water bowls or water fountains can help.
- Add water to your cat's dry kibble, or wet food to ther regular diet. You can also completely replace dry food with wet food until the condition resolves.
Although some pet parents, as well as some feline nutrition experts, believe that cats don’t have any physiological requirements for plant matter and therefore plant fiber, most cats, in fact, do. How is this possible? You don’t see cats eating grains and pumpkins in the wild! We hear you – however, cats who live in the wild often eat grass which supplies them with necessary fiber and nutrients, which in turn, help them eliminate all indigestible matter from their digestive tract. Here is how this works: naturally, cats lack the necessary enzymes to break down plant matter, so, when they eat vegetables and other plants, including grass, they sometimes throw up. While unpleasant (mostly for the owner), this allows the cat to get rid of all the things she cannot digest. This includes fur, bones, and feathers. Some experts speculate that certain indigestible animal parts themselves play a role of “fiber”, as they help bulk up the cat’s stool in a similar way, helping her defecate easier.
So what are indoor cats who cannot eat grass or dead animal parts suppose to do? Consume cat foods that are high in fiber; at least from time to time.

Dietary Requirements For Constipated Cats
All cats have the same basic nutritional requirements, and cats who occasionally or frequently struggle with constipation are no different; except in one aspect: they typically need more fiber.
When looking for the best cat food for constipation, pay attention to the following things:
- Quality and Amount of Protein
Cats are carnivores, and as such, have high protein requirements. Ideally, you want cat foods that contain good-quality animal protein sources (muscle meats, organs, meat meals, even quality by-products are all good), as well as moderate to high amounts of protein. Otherwise healthy felines tend to do well on high-protein diets, so anything between 30-40% of protein on dry basis is excellent. Cats with serious digestion problems, including constipation or diarrhea, as well as urinary tract problems, may have different protein requirements. In any case, more serious health problems are something you should discuss with your vet (some cats may need to switch to meat-free diets, for example).
- Quality and Amount of Fat
Cats need plenty of fat in their diet, especially those who are physically active. Look for foods that contain at least two different sources of fat, such as fish/salmon oil, canola oil, sunflower oil, chicken fat, pork fat, etc.
- Fiber (Carbohydrates)
As mentioned, many cats who suffer from constipation may greatly benefit from increased fiber intake. It’s worth noting that fiber comes in different forms and that each type reacts differently on the cat’s digestive system.
- Insoluble fiber (wheat bran, oat fiber, cellulose, various vegetables, etc.) helps bulk the stool and speed the bowel movement.;
- Soluble fiber (oat bran, barley, pectin, peas, carrots, etc.) feeds the good gut bacteria, helping improve GI motility disorders;
- Mixed fibers (psyllium, pea fiber, beet pulp, etc.) combine the benefits of both insoluble and soluble fiber.
Because fiber comes in different forms and has a variety of effects on the cat gut, it’s wise to start adding it slowly to your kitty’s diet. If your pet suffers from mild, occasional digestive issues, best foods for constipation will contain moderate amounts of fiber. If, on the other hand, your cat suffers from frequent and more serious digestive problems, they may require higher amounts of fiber in their diet. If this is your kitty, we suggest switching to a high-fiber cat food specifically crafted to treat constipation until their condition improves.

Q: Does raw feeding cause constipation?
Although raw feeding may have a number of benefits for some cats, the truth of the matter is that most domesticated cats do better on commercial kibble and canned cat food. There are a few reasons for this, but the most important one is that raw food, whether homemade or store-bought, is often deficient in certain nutrients. More often than not, these nutrients include indigestible matter, or - you guessed it - fiber.
This doesn’t necessarily mean you have to completely switch to cooked, commercial foods if you don't want to. If your pet is generally healthy and happy on a raw diet, it’s fine to keep feeding them the same way; however, if your cat has small, dry stools or is straining when trying to defecate, it’s a good idea to add high-fiber cat food into their diet, or to try fiber supplements instead.
Q: How many days can a cat go without pooping?
Healthy cats poop one to three times a day, every day. However, it’s normal for cats to sometimes go longer without defecating – up to 48 hours is tolerable. Anything past 2 days is a cause for concern, especially if you see your cat vomiting or straining to defecate (but nothing comes out). If this happens, get your cat to a vet for a prompt examination.
Q: Can cats die from constipation?
If constipation is left untreated, it can advance into obstipation, which is a serious condition where a cat cannot eliminate a mass of hard stools that have been accumulating in the colon. The intestines get stretched (megacolon) and the barrier that normally prevents fecal bacteria from moving into bloodstream, stops functioning. As a result, the animal becomes systemically ill, and if not promptly treated, dies.
That’s why it’s crucial to treat your cat’s constipation the moment you notice it. If water, different diet and supplements seem to help a little but not a lot, consult with your vet to rule out other serious health problems, such as intestinal tumors. This said, treating constipation in cats is easy if caught on time - that's why it's important to introduce wet food or dry food specifically designed for constipation the moment you notice your kitty straining in the litter box.
