Why can't my cat defecate?

Causes of constipation in cats

There are several reasons why a cat might have trouble defecating. Constipation is not a disease in itself, but a a symptom that something is wrong with the cat's digestive system or general health. The most common causes are:

Hair balls

Normally, a cat can expel hairballs without difficulty, either through vomiting or feces. But sometimes the accumulation of hair is so great that creates an intestinal blockage that prevents proper digestion and makes defecation difficult or blocked. This is especially common in cats of medium or long haircats with excessive licking due to stress or itching, and in those who do not brush regularly.

What to do?

It is very important brush the animal daily to reduce the amount of hair it ingests while grooming. It's also a good idea to give it malt for cats once or twice a week like mild laxative specific for hairballsDuring shedding seasons or in long-haired cats, the frequency may increase, always following the veterinarian's guidelines.

In cases of mild constipation, it can be given, always under professional supervision, lubricating products or specific fibers for catsSome people try home remedies like a tablespoon of vinegar; however, Administering vinegar or other home remedies without consulting a veterinarian is not recommended.as they may be ineffective or harmful. If we suspect that the hairball has caused a more serious obstruction (vomiting, lethargy, abdominal pain), it will be necessary Take him to the vet immediately. to assess enemas, medication, or, in extreme cases, surgery.

Lack of water (dehydration)

Cats that drink little water may have more difficulty defecating. When the body needs to conserve fluids, the colon absorbs more water from feces, which become very hard and dryThis happens more frequently in cats that eat only dry food, in older cats, and in those with kidney or metabolic problems.

Dehydration It can also appear if the cat vomits, has other illnesses, or does not have easy access to clean, fresh water during the day.

What to do? He should be given wet food (cans) of good quality or Soak their dry feed in water or homemade unsalted broth to keep him hydrated. It's very helpful to offer several wide bowls of water, separate from the food and the tray, and to assess moving water fountainswhich encourages many cats to drink more. If the veterinarian suspects significant dehydration, it may be necessary serum administered subcutaneously or intravenously in the clinic.

Obesity and lack of exercise

One of the consequences of obesity is constipationThis can be particularly serious the larger the animal's weight. Excess abdominal fat can slightly compress the organs and slow down intestinal transitIn addition, overweight cats tend to move less, which also decreases intestinal motility.

A very sedentary lifestyle, typical of cats that live exclusively indoors without stimulation, can lead to a sluggish colon. This is frequently seen in cats that spend many hours sleeping, without active play or daily interaction.

What to do? If our furry friend is carrying a few extra pounds, You have to take him to the vet for advice on what food you can give him and in what quantityand rule out associated diseases. We will also need to encourage daily exercise with interactive toys, feather wands, balls or circuits, dividing the sessions into several short periods throughout the day.

A healthy cat should spend at least several minutes a day to active gamesThis not only helps prevent constipation, but also improves your overall well-being.

Poor quality or low fiber food

If we give it low-quality food, with Lots of grains, by-products, and little actual meat content, low in fiber and moisture, your digestion will not be entirely goodThe stools may be scant, very hard, and difficult to pass.

In addition, sudden changes in diet or prolonged use of a food that is not well suited to your body can contribute to both episodes of constipation like diarrhea.

What to do? It is advisable to choose give him a feed that has a high percentage (at least 70%) of meat and that is free of cereals (corn, wheat, oats, rice). It is always recommended to supplement with quality wet food to increase water intake. In cats prone to constipation, the veterinarian may recommend specific gastrointestinal diets rich in fiber to promote regular bowel movements.

Injury or pain when defecating

The cat that has suffered a injury in the pelvic area or lower back Your cat may experience significant pain when defecating or urinating. Spinal, hip, or joint problems (such as arthritis in older cats) can also make it difficult for them to assume the correct position on the litter box, which can cause discomfort. Avoid using it and holding in your stool., worsening constipation.

What to do? You have to take him to the vet so they can examine your dog, take x-rays if necessary, and give you medication to relieve pain and reduce inflammation. In some cases, physical therapy, changes to the type of litter box (low sides, easy access), or home modifications may be required. If the pain is severe or there is a serious injury, the professional could insert a catheter or perform enemas under sedation until he got better.

Toys and foreign objects

If you have swallowed a toy or other object, it may got stuck in your digestive systemThreads, strings, rubber bands, pins, plastics, or small pieces of toys are especially dangerous, as they can cause anything from a persistent constipation until one severe intestinal obstruction that puts the animal's life at risk.

What to do? In these cases You need to go to the vet as soon as possible.especially if the cat is vomiting, has abdominal pain, is lethargic, or has not defecated for several days. Human laxatives should never be administered, nor should attempts be made to pull on a thread protruding from the mouth or anus.as it could cause internal perforations.

Medical problems and chronic illnesses

In addition to the above causes, there are metabolic or systemic diseases that can cause or worsen constipation:

  • Chronic kidney disease: promotes dehydration, so the stools become very dry.
  • Endocrine disorders conditions such as hypothyroidism or hypercalcemia can slow down intestinal transit.
  • Intestinal tumors or abdominal masses They can narrow the lumen of the colon and make it difficult for stool to pass through.
  • Intense stress or rejection of the litter box (due to dirt, noise, or unsuitable location) can cause the cat to hold it for too long before defecating.

In some cats, despite all tests, a clear cause is not identified. In these cases, we speak of idiopathic constipationwhich can become chronic and evolve into a megacolon, a dilation of the colon that loses its normal ability to contract.

What to do?

We will wipe the anal-genital area with a cotton ball moistened with warm water.Using one container for urine and another for feces, do this ten minutes after the kitten has eaten. It is important to make gentle movements, as if licking the kitten, until it urinates and defecates.

A kitten should normally defecate at least once a day; if two days pass and it hasn't, we will take it to the veterinarian to rule out malformations, infections, or digestive problems and to determine if it is necessary to use [a specific method/procedure]. specific laxatives or very controlled enemas.
