Best Food for Cats With Constipation: A Complete Guide

Identifying If You Need Cat Constipation Food

Before you go splurging the cash on the best cat food to help with constipation, it’s important you identify if you’re kitty is actually constipated.

Here are a few things to keep in mind.

How Do I Tell If My Cat is Constipated?

Depending on where your cat goes to the bathroom, it might be tricky to pick up on constipation.

If your cat spends nights roaming the outside world, it’s possible they do their business outside. There are a few other symptoms to watch out for.

Things like a lack of appetite, a tense abdomen, and hunched posture can be telltale signs of cat constipation.

If your kitty uses a litter box, it’s much easier to pick up on constipation. If your cat hasn’t ‘done its business’ in more than 24 hours, you might want to keep an eye on him.

Besides the symptoms mentioned earlier, you should look out for small, hard, dry stool and straining when in the kitty litter box.

Why is My Cat Constipated?

Constipation in cats can be caused by several things. Once you’ve recognized that your fur baby is struggling to go to the bathroom, finding the cause is a good idea.

Dehydration is one of the main reasons for constipation, but it’s not the only one.

Other reasons for this bathroom trouble could be kidney problems, feline megacolon, an imbalance of fiber in their diet, or over-grooming (leading to hair in the digestive tract).

Other reasons include cat litter tray avoidance, a side effect of some medications, or maybe they’re simply not getting enough exercise.

A hernia, a tumor, or a nerve disorder can also cause constipation in cats. If your furry friend ingests something that does not agree with them, it may obstruct their colon and cause a blocked tummy.

How Do I Treat Cat Constipation?

Once you’ve identified the cause, treating your cat’s constipation is reasonably straightforward. However, it’s a good idea to visit your vet to get professional advice.

Until then, you can increase hydration and make sure your cat has plenty of access to fresh water separate from their food. Alternatively, feeding them wet cat food can also increase hydration.

You can also help your kitty get active, invest in new cat toys, or even a laser to get them some extra exercise. This will not only get their body moving, but it’ll stimulate their intestines too.

You should also check your kitty’s fiber intake and if you need some high-fiber cat food. This is good to run past your vet as too much or too little fiber can result in upset tummies.

One of the best and most efficient ways to treat mild cat constipation is with the right food. Specially formulated food will help your cat get their intestines moving and sort out any tummy trouble.

What Is the Best Food for a Cat With Megacolon?

Firstly, it’s essential you know what megacolon is and how it affects your cat. In short, a megacolon is when your feline’s colon loses the ability to function as it becomes progressively bigger.

If your kitties megacolon is bad, then they’ll get constipated more often than not and most likely need a major operation. Luckily or fluffy friends tend to make a full recovery from these operations.

But what causes megacolon? There are many factors, from spinal cord injuries to tumors and excessive instances of hairballs (most notable in long-haired cat breeds like Maine Coons). Although the food choice won’t always change the outcome of a megacolon, they can help your kitty go number two.

Wet food options (especially the ones on this list) are best for fluffies suffering from megacolon or post-colectomy procedures. So if you’re kitty has had a megacolon, jump straight to the wet food options in this post.

Just had one of my cats over the New Year holiday become severely constipated and in pain. Not something you want to go through when veterinarians are on holiday as well.So out of pure anxiety and fear and not seeing this getting any better over night, I resorted to giving my cat 40 mg. Of my own prednisone tablets along with newly purchased hair ball remedy.Very relieved to say it worked and the Monday following the holiday she was at the vets office, though by this time everything was under control. Mamita is now on Denamarin prescribed meds.
