What is Cat Food for Constipation?

Cat food for constipation is a specific kind of food designed specially to support your cat’s digestive system. Your cat’s bathroom habits might not be the nicest thing to think about, but they’re crucial to the good health of your feline friend. You might need to offer your cat a food specially designed for constipation if you notice:

  • Straining: A well-hydrated cat with good digestion should be able to easily go to the bathroom when visiting their litter tray. If your cat is struggling, yowling, or making unhappy noises when going to the bathroom, there may be a problem.
  • Decreased defecation: Most cats will poop at least once every 24 hours. If you’re clearing the litter tray each day and not noticing any poop, this could be a sign your cat is constipated. Pay attention to how long your cat spends trying to go in the litter tray too.
  • Liquid feces: Though sometimes associated with diarrhea, liquid feces can sometimes be a sign of constipation too. This happens when there’s a blockage in your cat’s intestines, irritating the digestive system.

Cat food for constipation will often be recommended for your cat after you’ve seen a vet to rule out any other issues which might be causing an inability to go to the bathroom. There are a number of products on the market, and they range from biscuits and kibbles to specialist pate.


Features to Consider in Cat Food for Constipation

Generally, if you notice signs of constipation in your cat, the first thing you’ll need to do is visit your vet. This will help to rule out any risk of more serious health conditions which might be causing stomach problems for your cat. Your veterinarian may recommend the best food for your furry pal based on their symptoms, or you can look for constipation-busting foods yourself.

Some of the points you’ll need to consider include:

  • Dry/Wet food: Wet food is often a better bet for cats who have constipation. While dry food keeps for longer and costs less, it lacks the moisture kitties need. Make sure your cat has access to plenty of water alongside their food. Pate foods can be particularly useful for dealing with constipation because they’re easy to eat and digest.
  • Fiber: Fiber is extremely important for softening stools, minimizing their size, and making them easier to pass. Look for beneficial types of fiber sources like rice bran and beet pulp to give your kitty the extra boost they need. Make sure a higher amount of fiber in your cat food doesn’t come at the expense of the right amount of protein. It’s worth noting that fiber comes in different forms such as wheat bran, oat fiber, cellulose, various vegetables, etc.). These all help to bulk the stool and speed the bowel movement process.
  • Moisture: Dehydration is definitely one of the biggest causes of constipation, and if your cat is one of the many that doesn’t like drinking from a water bowl, wet food might be the only solution, due to its high moisture content. As mentioned above, pate has some of the best moisture content in wet cat foods.
  • Probiotics: Probiotics help to increase the production of short-chain fatty acids, which stimulate the production of feces. Foods that contain ingredients like pork liver and brewer’s yeast are extremely useful. Consider speaking to your vet about the extra probiotics, vitamins, and nutrients that might be helpful to your cat.
  • Allergens: If your cat has intolerances to certain ingredients, this can make it more difficult for their digestive system to work properly. Look for foods with minimal allergens to keep your kitty healthy.
  • Protein and calories: Though your cat food for constipation should be high in certain nutrients and fibers, it still needs a decent amount of protein and low-fat levels to ensure your cat’s good health. Don’t overlook the standard ingredients of healthy cat food.

Frequently Asked Questions

Does raw food cause constipation?

Raw feeding won’t necessarily cause constipation or any digestive problems in your cat. Often, raw feeding does give your kitty access to more moisture, but it can also reduce the number of times your cat has to go to the bathroom, due to a higher concentration of nutritional ingredients.

How long can a cat go without pooping?

This depends on several factors, but most pet experts will recommend speaking to a vet if your cat hasn’t defecated in longer than 48 hours. The main signs and symptoms to look out for include anything that indicates your cat is in distress, such as yowling sounds coming from the litter tray. You can also watch for lethargy, vomiting, or lack of appetite.

How serious is constipation?

In cats, when constipation is left untreated, it can eventually lead to obstipation, which causes a blockage throughout the entire digestive tract. This causes a significant strain on the internal organs of your cat, especially if they’re eating as normal. This is why it’s so important to see a vet as soon as symptoms begin to appear. Acting fast could save your cat’s life.

What are the dietary requirements of constipated cats?

The exact dietary requirements of your cat will differ depending on the cause of the constipation. However, in most cases, the best foods for constipation include low-residue cat food that tends to be a lot higher in protein, as well as high-fiber cat food. You can also consider looking into cat supplements that ease constipation, like multivitamins and pumpkin. Vets can sometimes prescribe medications for severely constipated cats.

What causes constipation in cats?

There are a number of issues that may cause constipation in cats, starting with blockages from hairballs and other foreign materials. Reluctance to use the litter box because it’s too dirty can also prompt your cat to “hold” going to the bathroom. 

Sometimes, constipation is caused by a lack of exercise – more common in older and overweight cats. Additionally, dehydration and lack of access to freshwater is a common problem. Other potential causes of constipation can include nerve damage, arthritis, and problems with the colon. Certain medications can influence cat bathroom habits too.

The Best Cat Food for Constipation: The Verdict

The ideal cat food for your cat will depend on a lot of factors, including what’s causing their initial bouts of constipation. If your cat seems to struggle with stomach problems and digestion issues regularly, a food like Blue Buffalo Wilderness grain-free could be perfect for getting things back on track. This dry food can be left out throughout the day, so it’s perfect for pet owners who don’t have the option to time wet feedings perfectly. 

The Blue Buffalo Wilderness cat food also contains a huge amount of protein and minimal calories to keep your kitty as healthy as possible. There are even added vitamins and minerals to ensure the longevity of your cat, and improve the health of their skin and fur. 

Remember, if you try a high-fiber cat food for constipation and give your cat plenty of water to drink, and they’re still showing symptoms, it’s important to speak to your vet as quickly as possible. Some cats will need additional medication and support aside from a change in diet.
