Cat Constipation
Is a Common Cat Illness

Cat constipation is very common and can occur at any age, although the risks increase the more elderly your cat becomes.

Constipation means that your cat is having difficulty to pass faeces, if it can do so at all.

This is usually because, for whatever reason, the faeces have remained in the bowel for too long.

The bowel reabsorbs moisture from the faeces, and so the longer it stays there, the drier and harder it becomes, making it even more difficult to pass from the body.

What causes cat constipation?

There are many possible reasons why you may have a constipated cat. These can include:

Poor cat care and poor diet, often with insufficient fibre / roughage in the food
Furballs
Dehydration (more moisture will be reabsorbed from the bowel if the cat is not getting enough to drink)
Lack of exercise and obesity
Stress
Dirty litter tray (if a cat puts off going to the toilet for any reason, constipation may result)
Obstruction, from foreign bodies such as bones Tumours and internal growths
Pain from abscesses and injuries
Pelvic injury or nerve damage from an accident or other trauma

How do I know if I have a constipated cat?

If your cat goes to the toilet outdoors then it may be difficult for you to spot the tell-tale signs of cat constipation. If you do suspect your cat is having problems, then keep them indoors with a litter tray for a couple of days so you can better monitor how they are getting on.

The signs of cat constipation to watch out for are:

Your cat passes hard dry faeces in very small amounts, if they can pass any at all.

Your cat keeps straining to go to the toilet, and possibly shows signs of pain as they do. This can be confused with episodes of cystitis where the cat keeps straining to pass urine.

Sometimes very liquid faeces can be passed and this may be confused with diarrhea.

This happens when the bulk of faeces has formed a 'plug' that the cat cannot pass. This irritates the bowel and more liquid faeces and mucus pass around the hard mass.

When constipation becomes a cat health emergency!

If your cat becomes lethargic and weak or starts to vomit, then please get your cat to the vet as soon as possible, as the condition is developing into a medical emergency.

What can I do to prevent cat constipation?

Always ensure that your cat has plenty of fresh clean water to drink. You can add some bran or other high fibre food to their diet.

Try canned pumpkin, vegetable meal or wholegrain mixed up in canned cat food. Introduce any changes to their diet slowly over a week or so.

Some medicinal paraffin can be added to their food if you suspect they are constipated. Be sure to follow the recommended directions carefully if using medicinal paraffin or other laxatives as too much will cause dirrahea.

You can also put your cat on a prescribed diet temporarily, or on a permanent basis if the problem keeps reoccurring - discuss this with your vet if necessary.

What can my vet do about cat constipation?

Your vet will want to know all about their diet, if there are showing any other symptoms and if they are on any medications. They will physically examine your cat, and possibly want to undertake further investigations such as taking blood tests, x-rays or scans.

They may need to give the cat some laxatives, of which there are many kinds. Another option is for an enema, and this usually requires sedation or to be done under anaesthetic.

The vet may need to put your cat on a drip to replace fluids if they have become dehydrated.

In severe and rarer cases surgery may be necessary, and your vet may need to take a biopsy or perform a colonoscopy if the problem is chronic and if it is difficult to diagnose a cause.

Prevention is better than cure in cat constipation.

We may provide the best cat care we can and still find we have a constipated cat sometime during its lifetime. Occasional episodes are often not too much to worry about and can be resolved at home.

Look again at the list of causes we have above to see if their is anything you can change to help prevent this problem arising, and always speak to your vet if you have any concerns regarding your cat health.
