Constipated Cat: How to Spot It and When to Worry

A constipated cat strains in the litter box, passes small hard dry stools, or goes fewer than once a day. Mild cases often improve with more water, wet food and a little fibre. But straining with nothing produced, crying, vomiting or a hard belly needs a vet the same day , it can look identical to a life-threatening urinary blockage.

Decide in 60 seconds

What normal looks like

Most adult cats pass one, sometimes two, formed but moist stools a day. The stool should be brown and hold its shape without being rock hard. Skipping a single day is not automatically a crisis, but two or more days with no stool, or repeated squatting with little result, means something is backing up.

Signs your cat is constipated

Watch for repeated trips to the litter box with little or no result, prolonged squatting, and vocalising or tensing while trying to go. You may see small dry stools stuck to the fur or left just outside the box. Other clues include reduced appetite, a tucked-up or tender belly, hiding, and less grooming. Some cats vomit when the colon is very full.

Hard, dry, pebble-like stools are the classic sign of feline constipation.

Why cats get constipated

Dehydration is the single biggest driver , cats evolved from desert animals and often drink too little. Other common causes include hairballs, low-fibre or all-dry diets, obesity and inactivity, pain from arthritis making litter-box posture hard, stress or a dirty box, and swallowed foreign material. Kidney disease and some medications also dry out the stool. Older cats often have several of these at once.

Safe things to try at home

For a mild, otherwise-bright cat, focus on hydration. Add a second water bowl or a pet fountain, switch some or all meals to wet food, and add a splash of water or unsalted broth to meals. A vet-recommended fibre source such as a small amount of plain canned pumpkin can help some cats. Encourage movement with play, keep the litter box spotless and easy to enter, and brush long-haired cats daily to cut hairball load.

More water and wet food are the simplest first steps against mild constipation.

When it keeps coming back

Recurring constipation deserves a full work-up. Your vet may check hydration, run bloodwork for kidney disease, take an X-ray to see how backed up the colon is, and screen for arthritis or dental pain that reduces appetite and drinking. Long-term management usually combines a moisture-rich diet, a prescription fibre or stool softener, and treating the underlying cause. Caught early, most cats do well; left too long, the colon can stretch permanently.

When to call your vet

• Signs are getting worse over hours, not better

• Pain, persistent vomiting/diarrhea, or neurological signs

• You needed force or guesswork to keep going at home

Common mistakes

• Waiting because the animal 'still looks okay' while prey species hide pain

• Changing five variables at once so you cannot tell what helped

• Copying drug doses from social media

• Skipping species-appropriate husbandry while buying more gadgets
