What can be the reasons for a cat’s constipation?

At the beginning it is worth determining how often cats should defecate, because it looks different in different species of animals, which people often do not realize. In the case of healthy, healthy cats eating good-quality food (wet, well-balanced and meat), the bowel movement occurs once a day or once every two days. The stool is hard, rather dry and odorless or almost odorless.

In cats on the BARF diet (Biologically Appropriate Raw Food), i.e. a properly composed and balanced mixture of raw meat, offal and meat bones with supplements, one bowel movement for two or three days is the norm. Stool with this diet has a similar, or even more compact texture and is usually completely odorless.

So the problem starts if, first of all:

    • When cleaning the litter box, we notice that these norms have been exceeded, and secondly, the cat expresses his behavior that he has trouble passing faeces
    • The animal may tell us this in various ways, but certainly any pain, blood or mucus present in the feces or defecation outside the litter box should worry us

In the case of a poop found outside of the litter box, let’s not stress the animal with shouting or scolding – he did not do it maliciously. It may also happen that the cat will enter the litter box and try to defecate, but he will not succeed. So where do these cuvette problems come from?

Ingestion of indigestible items

First of all, cats often consume indigestible objects and materials that lead to intestinal obstruction and thus constipation. Such items are most often all kinds of pieces of fabric, strings, ribbons from gifts, fishing rods and other toys, plastic small parts, plants. If you notice that the cat has just eaten such an object, or if we already see its end from the anus side, you should not try to help the animal yourself.

By pulling such a string or ribbon, you can only damage the intestines. Surgical intervention at the vet may be necessary, especially if the foreign body is long, has a sharp edge, or if you notice severe pain or blood. If the cat is behaving normally and the object consumed was small, we can contact the veterinarian by phone and follow his instructions.

Inadequate diet

Cat’s constipation also often occurs through hair accumulated in the intestines, or rather – licked fur, commonly known as “fluff”. Usually to the so-called confusion occurs when a cat is on an inappropriate diet and its digestive system is not able to get rid of the hair collected in it. If the diet is sufficiently moist and fatty, cats are unlikely to have such problems. It is worth planting grass especially for the cat, which it will be able to gnaw. It will help him get rid of his hair.

For cats whose carers prepare meals themselves or animals that are fed, constipation may occur due to too many bones in the diet. Of course, bones are a very important element of the menu and should be in it (only in raw form and always with meat, never bare bones), but it is very important to maintain the right proportions with the other ingredients.

Behavioral causes

Behavioral causes related to cat constipation are mainly associated with the litter box itself. The first thing to look out for is the cleanliness of the litter box. Many cats do not empty into a dirty toilet. In addition, you must remember that cats are animals that love routine, repeatability, which is why stress caused by changes, such as a new animal, new household member, moving house, renovation – can cause cat constipation or, conversely, diarrhea.

Health factors

Cat constipation caused by health factors is primarily due to obstruction or weakening of the colon. Obstruction of the colon can be caused by pseudoprostasis, rectal repositioning (called perineal hernia), disorders located in the intestinal lumen (tumor, granuloma, scarring, foreign body in the rectum, congenital narrowing) or outside the intestinal lumen (also tumor and granuloma, but also granuloma) , combined pelvic fracture, prostatic hyperplasia, prostate or periglandular cyst, enlargement of lumbar lymph nodes).

Weakness of the colon can be caused by some general disease, for example hypercalcaemia, hypokalemia, hyperthyroidism or Chagas disease. It also happens that it results from local neuromuscular damage, such as spinal cord injury, pelvic nerve damage, dysautonomy or chronic, massive dilatation of the colon causing irreversible stretching of its muscular tissue. A cat may refuse to defecate if it is unable to take the right position, and this may be due to orthopedic or neurological problems.

Drug action

Cat constipation can also be caused by iatrogenic factors, i.e. those that are the result of medical treatment and actions. Here, attention is drawn to drugs such as opiates (psychoactive substances), sucralfate (gastric mucosa), barite (a means used as contrast in imaging diagnostics) or anticholinergic drugs. Another reason for constipation may be severe dehydration.

How do you diagnose constipation?

The veterinarian will certainly interview the cat’s guardian. In an interview he will try to find iatrogenic, dietary, environmental and behavioral causes. Vet may carry out stool and rectal examination. Serum biochemistry or ultrasound may be required. Colonoscopy is also an indication if the cause was not palpable.

How can you help a cat with constipation?

Depending on the cause of constipation, you can help your cat in different ways. Usually, the first step is to give paraffin oil, which will facilitate bowel movements. However, you should either give it to a veterinarian or an experienced person, because it is easy to let the cat choke with oil. Rectal ingot and removal of residual fecal masses may be necessary.
In the case of diet errors, you should analyze the balance of homemade meals, including the proportion of bone in the diet.

In the case of a tame cat, it will be helpful to plant grass that he can chew, or to add a bit of animal fat to the food – for example butter or lard (without salt, onions, greaves or other!).

If the kitten does not deal with behavioral reasons, find the source of the problem and eliminate it. The cat must always have access to the litter box. The cuvette should be of the right dimensions so that the cat can fit in and turn there easily; best discovered. The location of the litter box can also be a problem – if the cat is not completely interested in it, let’s find a different corner in the house for her. It is also practical to have an additional litter box for cats who are reluctant to use even a slightly soiled toilet.

If it turns out that the cat’s constipation is caused by stress, he should be given peace and comfort. It is worth taking care of the game while maintaining hunting behavior, proper diet, psychophysical fatigue of the cat and routine every day (e.g. meals at the same hours). In addition, you can use preparations with tryptophan, which works gently silencing, or cat pheromones in the form of a pheromone collar or in a diffuser connected to the socket. In case of health problems, you will need to have appropriate treatment or even surgical intervention.

Frequently Asked Questions

Is cat constipation an emergency?

Constipation—the inability to routinely and easily evacuate the bowels—is a common feline malady. … “Straining in the litter box may be a sign that the cat is harboring a lower urinary tract disease and is unable to urinate properly,” he says, “and that would surely call for emergency care.

Can cats die from constipation?

Constipation may sound like an innocuous enough problem, but for some cats constipation can lead to disease processes that can even be life ending. … Feces are often hard and dry, which may cause cats to strain or have difficulty passing feces.

Can I give my cat olive oil for constipation?

Cat laxative gels Mineral oil and olive oil are not recommended due to the danger of inhaling mineral oil and the high dose of fat in olive oil causing digestive upset.

How long can cat go without pooping?

Cats that stop eating for any reason will obviously have less in their digestive tracts, so they may go less often. But if four to five days go by without evidence in the litter box, it’s time to be concerned.
