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.
Treating constipation is a process of elimination.
First, see a vet.
They’ll look for clues, including:
- 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.
Other risk factors related to diet include:
- 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 fiber adds bulk and soluble fiber adds moisture.
Whilst soluble fiber helps with lubrication, insoluble fiber dries feces.
Why use a low residue diet?
- 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.
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
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.
Speak with a vet about managing health problems.
