Laxatives For Cats: Safe Or Not?

Constipation in cats is a common condition that can be caused by dietary issues, dehydration, lack of exercise, chronic conditions, and certain medications. While mild cases of constipation may be treated with dietary and lifestyle changes, more severe or persistent cases may require medication or veterinary intervention.

Laxatives can be an effective treatment for cat constipation, but they should only be administered under the guidance of a veterinarian. Human laxatives, for instance, can be lethal to cats, and even veterinary-prescribed laxatives can have side effects. Over-the-counter laxatives and stool softeners may help with mild constipation, but it's important to seek veterinary advice to prevent the condition from worsening.

Veterinarians may recommend rehydration, enemas, or specific laxatives depending on the severity and cause of constipation. It's important to note that treatment should be tailored to the individual cat's needs, taking into account their overall health, age, and any underlying medical conditions.

Human laxatives can be lethal to cats

If your cat is constipated, you should first try to address the issue through basic treatment methods. Constipation may be caused by a lack of exercise or an issue with their diet. In this case, getting rid of constipation may be as simple as ensuring your cat is eating a healthy diet and getting plenty of exercise. However, it's important to note that constipation may also be caused by overgrooming, which could be a sign of cat skin allergies.

If your cat is constipated for several days, talk to a vet about getting a cat laxative prescription. Your vet will be able to advise you on the best course of action, which may include a prescription for Microlax or Lactulose. Over-the-counter laxatives can work for mild constipation, but for more severe cases, your veterinarian might need to prescribe a stronger medication or even administer an enema.

There are also some simple methods you can try to relieve constipation in cats. You can start by giving your cat a gentle belly rub to help relieve pain and move any impacted faecal matter through their bowels. You can also simulate what mother cats do to stimulate their kittens to defecate: take a cloth, wet it with warm water, and rub it around your cat's anus.

In addition to addressing the immediate issue of constipation, it's important to prevent it from becoming a vicious cycle. The key to easing constipation is to prevent stools from drying out and get them moving as soon as possible. You can do this by increasing your cat's water intake and reducing their stress levels.

Laxatives can cause side effects in cats

Laxatives can lead to dehydration, as they inhibit water absorption in the colon. This can be dangerous for cats, as constipation is often caused by dehydration in the first place. Electrolyte imbalances can also occur as a result of using laxatives.

Another potential side effect of laxatives is worsened constipation. This can happen if the wrong type of laxative is used or if the cat's constipation is caused by too much fibre in their diet. Lubricant laxatives, for example, can interfere with the absorption of nutrients when used long-term because they coat the intestine and prevent nutrient absorption.

Laxatives can also cause irritation. For example, enemas can irritate the colon if performed too quickly. To avoid this, they should be performed slowly.

In addition, the use of mineral oil and liquid paraffin as laxatives is limited to rectal administration only due to the risk of aspiration.

Laxatives can be prescribed by a vet

If your cat is suffering from constipation, it's important to seek veterinary advice. While over-the-counter laxatives can help with mild cases, you should still consult a vet to ensure the best treatment for your cat.

Laxatives are typically prescribed when constipation is severe and hasn't improved with other methods. Vets will consider various factors, including the cause of constipation, your cat's overall health, age, and any underlying medical conditions.

Lubricant Laxatives

These laxatives, such as white petrolatum, mineral oil, and liquid paraffin, encourage the passage of feces by coating the stool and intestines with a lubricating film. They are typically used as a short-term treatment for mild constipation. However, long-term use may interfere with nutrient absorption.

Emollient Laxatives

Emollient laxatives, like docusate sodium (DSS), promote the retention of water within the feces, making it softer and easier to pass.

Osmotic Laxatives

Osmotic laxatives, including lactulose and Miralax® (polyethylene glycol 3350), are commonly used in cats. They work by drawing water into the colon, softening the stool, and stimulating bowel movements. These laxatives are generally considered safe for long-term use.

Stimulant Laxatives

Stimulant laxatives, such as cisapride and metoclopramide, are reserved for severe constipation unresponsive to other treatments. They trigger contractions in the colonic muscles, helping to push out the stool.

When dealing with cat constipation, it's crucial to follow your veterinarian's instructions for the chosen laxative and ensure your cat has access to fresh drinking water.

Over-the-counter laxatives can be used for mild constipation

Over-the-counter laxatives can be used to treat mild cases of constipation in cats. However, it is important to seek veterinary advice as soon as possible, as constipation can quickly become a more severe problem.

There are four main types of laxatives:

Lubricant Laxatives

Lubricant laxatives coat the stool and intestines with a lubricating film, easing the passage of faeces. Examples include white petrolatum, mineral oil, and liquid paraffin. These may be helpful for mild constipation as a short-term treatment option but can interfere with nutrient absorption if used long-term.

Emollient Laxatives

Emollient laxatives promote the retention of water within the faeces. An example is docusate sodium (DSS).

Osmotic Laxatives

Osmotic laxatives draw water into the colon from the surrounding tissues, helping to soften the stool and stimulate bowel movements. Osmotic laxatives are generally considered safe for long-term use. Lactulose and Miralax (polyethylene glycol 3350) are two osmotic laxatives commonly used in cats.

Stimulant Laxatives

Stimulant laxatives increase the contractions of the colonic muscles, helping to move stool through the colon and out of the body. They are typically only used for severe constipation that does not respond to other treatments. Examples include cisapride and metoclopramide.

It is important to note that human laxatives can be extremely toxic to cats and should not be given to them. Always consult a veterinarian before giving any medication to your cat.

Laxatives can be dangerous if not properly treated

Constipation in cats can lead to several health risks, some of which can be life-threatening if not addressed promptly. One such complication is megacolon, a condition where the colon becomes abnormally enlarged and loses its ability to function properly due to consistent stretching. This can occur when a cat suffers from chronic constipation.

Another severe form of constipation is obstipation, where dry, hard stool becomes impacted in the colon and rectum, making it difficult for the cat to pass any stool or gas. This can be extremely uncomfortable and even painful for your cat.

Additionally, toxemia is a condition that can develop when constipation is left untreated for an extended period. In this case, the stagnation of faeces in the colon can result in the absorption of toxins into the bloodstream, posing serious health risks.

It is important to be cautious when administering any medication to your cat, including laxatives. Human laxatives, in particular, can be lethal to cats, so it is crucial to only give your cat laxatives that have been prescribed or approved by a veterinarian. Improper or unsupervised use of laxatives can lead to complications such as dehydration and electrolyte imbalances, and may even worsen constipation.

Therefore, it is essential to consult a veterinarian if your cat is experiencing constipation. They can help determine the underlying cause, recommend appropriate treatment options, and guide you on the safe and effective use of laxatives for your feline friend.
