Constipation in cats: when stools become too hard

Hard stools, straining and infrequent bowel movements deserve attention. Fluid intake, swallowed hair, exercise and pain can all play a role.

Constipation in cats: when stools become too hard

Why cats sometimes have problems defecating

Many cat owners pay close attention to whether their cat is eating, drinking and using their litter tray. What is often overlooked: the consistency and frequency of defecation.

Hard stool in particular can be an indication that something is not going well. Constipation is one of the most common digestive problems in cats and should not be underestimated.

What is constipation?

Constipation occurs when stool:

Some cats then spend significantly more time in the litter tray without passing a lot of faeces.

  • becomes unusually hard
  • can only be excreted with difficulty
  • accumulates in the intestines
  • is passed less often than usual

How do you recognise constipation?

Typical signs can be:

Some cats even meow when trying to defecate.

  • Straining in the litter tray
  • very small or hard balls of faeces
  • rare defecation
  • Pain when defecating
  • restlessness
  • Loss of appetite
  • Vomiting
  • retreat

Why constipation is common in cats

Cats are naturally considered poor drinkers. This is exactly why various factors can promote the development of constipation.

Too little fluid intake

One of the most common causes is simply:

Too little water.

If the body does not receive enough fluids, it withdraws more and more water from the intestinal contents.

The result:

The stool becomes harder and drier.

Dry food and liquid

Dry food is not automatically bad. However, it contains significantly less water than wet food.

That's why it's particularly important that cats who mainly eat dry food drink enough.

However, many cats do not achieve this amount of fluid on their own.

Swallowing hair during grooming

Cats spend a large part of their day grooming.

Hair is regularly swallowed.

These are normally excreted without any problems. However, in larger amounts, hair can contribute to:

Those particularly affected are:

  • the stool becomes firmer
  • Hairballs occur
  • the intestines are put under greater strain
  • Long-haired cats
  • Cats during seasonal moulting

Lack of exercise

Exercise supports natural intestinal activity.

Cats that don't get much exercise can develop slower digestion.

Indoor cats in particular often benefit from:

  • Opportunities to play
  • Climbing opportunities
  • activities

Pain as a possible cause

Sometimes the problem is not directly in the intestines.

Cats in pain may avoid defecating.

Possible causes can be:

Older cats in particular are more often affected by this.

  • Osteoarthritis
  • Back problems
  • Injuries
  • Diseases in the pelvic area

Being overweight increases the risk

Being overweight can also limit mobility and affect digestion.

In addition, some overweight cats find it more difficult to adopt a comfortable position to defecate.

Stress can affect digestion

Cats are often sensitive to changes.

This includes:

Stress can also affect the gastrointestinal tract.

  • Relocations
  • new animals
  • Changes in the household
  • unfamiliar routines

When should you go to the vet?

A cat should not be constipated for long periods of time.

A vet visit is important if:

Untreated constipation can have serious consequences.

  • There is no defecation for a longer period of time
  • the cat strains hard
  • Pain occurs
  • vomiting occurs
  • the cat no longer eats
  • the stomach appears bloated

Why you shouldn't just wait and see

Many cats only show symptoms very late.

While dogs often communicate more clearly, cats often suffer in silence.

This is precisely why it is worth taking changes in toilet behaviour seriously.

Prevention in everyday life

The following can help support normal digestion:

Every cat is individual.

  • adequate fluid intake
  • regular exercise
  • Weight control
  • Grooming during shedding
  • Observation of faeces

Conclusion

Constipation in cats is a common problem and is often caused by several factors at the same time. Too little fluid, hair ingestion, lack of exercise, or pain can all contribute to stool becoming too hard.

If you recognise changes early and remain vigilant, you can help ensure that your cat's digestion remains as stable as possible.
