How To Treat Constipation In Cats

cat constipationConstipation is the infrequent passage of hard, dry feces. There are a number of causes of constipation in cats which are covered in more detail here. Cats usually pass a stool once or twice a day, if the feces remain in the colon for too long, they become dry and hard, making them more difficult to pass.

The goal in treating constipation is to increase fluids and fibre in the diet. There are several ways you can do this. However, if you do not notice an improvement within 12-24 hours, do see your veterinarian because constipation can quickly turn into obstipation, which is serious.

Hairballs can be a cause of constipation if you have a cat who is prone to constipation you may want to consider feeding him a specially formulated "hairball diet". Also, make sure you groom him regularly to remove loose hair from his coat.

How to treat constipation in cats:


Dehydration is a common cause of constipation in cats. He must have access to fresh, clean drinking water is essential.


Adding fibre to your cat's food can help with mild constipation. There are several ways to do this.

  • Add 1/2 - 1 teaspoon unflavoured Metamucil to canned food.
  • Pumpkin is high in fibre and water and is an excellent way to get more fibre into your cat's diet. Add 1-2 tablespoons of canned (not the canned variety for pumpkin pie as this contains sugar) or boiled pumpkin to your cat's meal.


  • If your cat is prone to constipation, switch him to a canned or raw diet, which has a higher water content.
  • If your cat is prone to hairballs, switch him to a hairball diet.

Litter trays:

  • Cats can be quite fussy when it comes to their litter tray and if they are not happy, this can cause them to override their urge to defecate. Make sure there are enough litter trays (one per cat, plus one extra), make sure they are regularly scooped and keep them in a low traffic area.

When to see a vet:

  • If your cat appears to in pain and is unable to pass any feces at all.
  • If your cat has any accompanying symptoms such as loss of appetite, lethargy.
  • If your cat is still passing only small amounts of feces 12-24 hours after you have added fibre to his diet.

It should be noted that a cat straining to go to the toilet is assumed to have constipation, however, cats are prone to developing urinary blockages which is a medical emergency. If you notice your cat straining to go to the toilet, licking his genitals, meowing, urinating outside the litter tray, see your veterinarian immediately.

What not to do:

DO not attempt to treat constipation with the use of mineral or vegetable oils via syringe as the oil can very easily end up in your cat's lungs and cause aspiration pneumonia.

Do not treat your cat at home with laxatives or medications. Always consult your veterinarian before you medicate your cat.
