Types of diarrhoea in cats by pathophysiology

1 comment

Diarrhoea in cats is one of the most common symptoms when there is an illness or gastrointestinal upset but it can also occur for other reasons. For example, after deworming.

This gastrointestinal problem can be defined as an increase in the frequency, fluidity or volume of faeces and appears because there is an increase in faecal water content due to different pathophysiological mechanisms. It is a common complaint and as long as it does not last for a long time or occurs continuously, it is not excessively worrying. However, you should pay attention if your kitten has diarrhoea and know what to do to solve this problem.

At Kunkay we help you take care of your pet's health by offering you the best natural supplements to complement their diet by providing them with the vitamins, minerals and nutrients they need to grow healthy, strong and happy. In addition, we also share with you all kinds of useful tips so that you can give your kitten the best care.

For example, in our blog we have answered questions such as what to do if my cat has a fever or we have told you which foods cats can eat (and which ones can't). This time we tell you everything you need to know about diarrhoea in cats, we explain how long this problem usually lasts and the main differences that this ailment has depending on its pathophysiology.

1. How long does diarrhoea usually last?

Depending on the source of diarrhoea in cats, it can last up to three or four days. If the diarrhoea lasts longer than this, even if you are taking measures to combat it, you should consult a vet.

In the case of small kittens or senior pets, you should pay special attention as this gastrointestinal ailment can be fatal if you do not take the appropriate measures.

The moment your kitten shows signs of diarrhoea, make sure it is well hydrated and start a half-day fast. If there is no improvement, see your vet to rule out more serious problems. Also, if you suspect your cat may have ingested a poisonous or unhealthy substance such as chocolate, seek emergency veterinary care at the first sign of symptoms.

2. Osmotic Diarrhoea

Also known as malabsorptive diarrhoea, this is the most common type of diarrhoea in dogs and cats. It occurs because the animal has nutrients in its intestine that cannot or have failed to be absorbed.

This situation causes what is known as passive diffusion of water into the intestinal lumen, resulting in softened stools or even watery diarrhoea.

Osmotic diarrhoea can be caused by dietary overload, bile salt deficiency, pancreatic insufficiency or the presence of a disease affecting the mucosa of the small intestinal system.

3. Exudative Diarrhoea

This type of diarrhoea in cats occurs when there is a change in the permeability of the intestinal mucosa resulting in the loss of plasma proteins and other circulating components in the faeces.

It is usually associated with an infection that can either decrease intestinal mucosal integrity or increase intestinal hydrostatic pressure. It often begins in a form similar to secretory diarrhoea that later becomes complicated, usually also accompanied by fever.

4. Diarrhoea due to Dysmotility

This is a type of diarrhoea that occurs without altering the absorption capacities of the intestinal mucosa. What happens is that the muscles or nerves that control the functioning of the digestive system are not able to perform their function properly, causing a "piping" effect in the intestine.

In other words, the animal is not able to control the contractions to contain and evacuate the faeces properly.

5. Secretory Diarrhoea

This type of diarrhoea in cats occurs when an abnormal amount of extracellular fluid is excreted. Specifically, it is a condition that occurs when the secretion of fluids and electrolytes by mucosal cells is increased.

In its early stages it is very similar to osmotic diarrhoea with the difference that in the case of secretory diarrhoea, the animal will continue to excrete despite fasting.

6. Diarrhoea after Deworming

Diarrhoea is a fairly common side effect after deworming and can last for two to four days. If it persists for more than this period, especially if it lasts longer than a week, it is important to consult a veterinarian to rule out more serious problems.

Cat supplements can be a great way to support your kitty's gastrointestinal health and give them the help they need to recover from problems such as diarrhoea. Within our wide range of products this time we recommend Enterokun Severe and Enterokun Mild from the Digestive Recovery line, two natural supplements that are used to treat diarrhoea and counteract its side effects, both in mild and severe acute processes and in chronic and recurrent disorders. There are many diseases that cats can suffer from, and diarrhoea is one of them.
