Constipation is common in middle-aged and older cats.

Untreated, it leads to nasty problems like megacolon which require surgery.

60% of constipation cases in cats are idiopathic. This means your vet won’t find a cause.

Adjusting your cats diet helps treat idiopathic constipation, giving your cat relief.

In this article I’ll help you with a buying guide to know what to look for. Then, I’ll run through my top choices and why I picked them.

Finally, I’ll go through frequently asked questions on the topic.

I am not a veterinarian and I recommend seeking the advice of a vet for any further questions. This article is not intended as a replacement for medical advice.

Let’s go.

Buying Guide

Treating constipation is a process of elimination.

First, see a vet.

They’ll look for clues, including:

  • Medication
  • Change in behavior (e.g. litter box avoidance)
  • Stress (e.g. change in routine)

Older cats are at a higher risk of constipation.

Stress also increases risk.

5.6% of UK rehoming shelter cats had constipation in a 2019 study, possibly related to stress.

Cat shelters and similar can increase stress and constipation in cats.
Cat shelters and similar can increase stress and constipation in cats.

Other risk factors related to diet include:

  • Dehydration
  • Overweight
  • Kidney disease

The goal of a constipation diet is to stimulate the bowel by adding bulk or moisture.

Food sensitivities also impact bowel function. Grains and fillers may irritate digestion.

If undiagnosed, it’s called idiopathic constipation (lingo for ‘we don’t know’). There’s not many trials in this area.

So this results in trial and error.

Here’s what to try:

Use Wet Cat Food to Loosen up Poos

Dehydration can cause constipation.

Senior cats are at risk. As are cats on a dry cat food only diet.

Wet food offers moisture to loosen things up. It also cuts the risk of urinary stones.

Try a Low Residue Diet

A low residue diet is a low fiber diet.

A low fiber diet (<10%) helps make passing feces easier.

What about fiber type?

There’s two types:

  • Insoluble
  • Soluble

Insoluble fiber adds bulk and soluble fiber adds moisture.

Whilst soluble fiber helps with lubrication, insoluble fiber dries feces.

Why use a low residue diet?

Reasons include:

  • Less bulky poo
  • Helps motility
  • Better results with enema

A low residue diet is a short term fix.

Clear up bulk and get back to normal.

What to look for?

Choose cat food with less than 10% fiber dry matter basis.

Most wet cat foods achieve this.

How a high fiber diet increases constipation risk in cats.
A high fiber diet can make poos larger and harder (especially insoluble fiber).

Add Psyllium to Loosen Things Up

Add 1-4 tsp psyllium to soften poo.

Psyllium is a soluble fiber.

As we’ve mentioned, it helps with lubrication.

Soluble fiber also ferments to short-chain fatty acids (SCFA). These fatty acids aid smooth muscle function of the bowel (i.e. stimulate movement).

A one month trial of psyllium helped treat constipation in 14 cats. The dosage was between 1-4 tsp of psyllium per 3 ounce can of cat food.

Other sources of soluble fiber include:

  • Beet pulp
  • Guar gum
  • Pectins

Some wet cat foods contain these ingredients, which can benefit constipation.

So either look for wet cat food with either of those ingredients or add psyllium.

Try an Elimination Diet

7-10% of cats have irritable bowel syndrome (IBS).

Constipation is one side effect of IBS (called IBS-C).

The cause of IBS is unclear. Food intolerance is one possible cause.

Elimination diets help isolate the problem food that irritates digestion.

To start, you need to use a novel protein cat food. This is anything not found in most cat foods (e.g. venison, rabbit).

Another alternative is a hydrolyzed formula.

Choose novel protein food that meets the needs as a complete meal per AAFCO’s guidelines on cat nutrition.

More on elimination diets here. This one’s best talked over with a vet.

Treat the Underlying Cause

Here’s what increases constipation risk:

  • Weight gain
  • Kidney disease
  • Electrolyte imbalance

Keep your cat at a healthy weight.

That’s a 5 on the body condition score chart. See here.

A study found corn gluten meal decreased fecal moisture compared to fish meal.

How Did I Choose These Products?

I’ve analyzed over 50 popular cat foods. Many tested with my cat team.

I sorted cat foods based on:

  • Nutrition
  • Ingredients
  • Taste
  • Cost
  • Trust

We use a qualitative and quantitative scoring system.

I picked out options that best help with constipation. I’ve went for wet cat food under 10% fiber.

I’ve excluded dry cat food since this won’t be the best choice for constipated cats. Whilst I’m not saying you can’t give your cat dry food, it’s less preferable.

Can I Give My Cat a Laxative?

Bulking agents increase size. Can help stimulate bowel motions.


Always call a vet first if you suspect constipation.

Since there’s a wide variety of causes, it’s hard to pin down yourself.

If they can’t find the cause (idiopathic constipation) try adjusting diet. Wet low residue cat food with added psyllium can help.
