What Happens If My Cat Eats A Earthworm?

Is your cat a curious little explorer, always sniffing around and getting into mischief? Have you ever caught them chowing down on an earthworm? As pet owners, we’ve all witnessed our feline friends do some unusual things, but the thought of them eating a live worm might have us wondering what will happen next. In this blog post, we’ll explore the question “What happens if my cat eats an earthworm?”.

Earthworms are a staple in a cat’s diet if they live outdoors since they’re an excellent source of protein. Cats have a natural instinct to hunt and eat small prey, and earthworms are no exception. However, it’s essential to note that not all worms are safe for consumption. Ingesting toxic worms can be harmful and sometimes even fatal for your kitty.

In this article, we’ll dive into what earthworms consist of, their nutritional benefits to cats, whether they’re harmful or not, and the dangers associated with eating poisonous worms. We’ll also examine the potential side effects of eating an earthworm and what to do if our feline friend shows symptoms of sickness.

So, if you’re a cat lover who’s curious about the effects of a wormy snack on your furry friend, grab yourself a cuppa and let’s get started.

Is Eating Earthworms Toxic for Cats?

While earthworms are generally not toxic or harmful to cats, there are still some potential risks to consider.

Let’s start with the good news – earthworms themselves are not poisonous and can even be a healthy addition to a cat’s diet as they are packed with protein. However, there are potential dangers associated with this behavior.

First and foremost, if the earthworms have been exposed to pesticides or other toxins, those toxins can be passed on to your cat. Eating earthworms that have ingested something toxic like a poisonous plant or contaminated soil can also put your cat at risk.

Another concern is the risk of intestinal blockages. If your cat eats too many earthworms or consumes them whole without proper chewing, they can become tangled in their intestines, leading to a serious and potentially life-threatening blockage.

In addition, earthworms can carry parasites like tapeworms and roundworms, which can be transmitted to your cat if they eat an infected worm. Symptoms of parasitic infections in cats can range from mild to severe, so it’s important to consult with your veterinarian if you suspect your cat has ingested an infected earthworm.

Lastly, consuming large amounts of earthworms can cause gastrointestinal upset in cats, leading to vomiting or diarrhea. If you notice any signs of digestive discomfort in your cat after they have eaten an earthworm, it’s best to monitor them closely and contact your veterinarian if the symptoms persist.

Potential Risks of Parasites from Eating Earthworms

However, these seemingly harmless creatures can pose potential risks of parasites that can harm your pet’s health. Parasites are harmful organisms that live inside another organism and feed off it, causing harm and disease. Earthworms are known to carry different types of parasites, including roundworms, tapeworms, and hookworms.

Roundworms are the most common type of parasites found in earthworms. If your cat eats an earthworm infected with roundworms, the parasites can travel through their digestive system and infect other organs such as the liver, lungs, and heart. Symptoms of roundworm infections in cats include vomiting, diarrhea, weight loss, and a potbellied appearance.

Tapeworms are another type of parasite that can be found in earthworms. These flat, segmented worms can grow up to several feet long. If your cat eats an earthworm infected with tapeworms, they can develop tapeworm infestations in their intestines. Symptoms of tapeworm infections in cats include scooting their bottoms on the ground, vomiting, diarrhea, and weight loss.

Moreover, hookworms are also a type of parasite found in earthworms. These small and thread-like worms attach themselves to the intestinal lining and feed off blood. If your cat eats an earthworm infected with hookworms, they can develop anemia due to blood loss. Symptoms of hookworm infections in cats include lethargy, pale gums, and decreased appetite.

Symptoms of Parasitic Infections in Cats

Parasitic infections are a common issue among cats, particularly those that enjoy outdoor adventures. A cat’s prey, such as earthworms, can carry parasites that lead to infection. As a responsible cat owner, it is crucial to be aware of the symptoms of parasitic infections in your feline friend.

Vomiting and diarrhea are typical signs of parasitic infections in cats. Roundworms, hookworms, and tapeworms are common culprits that cause these symptoms. If you notice your cat has an upset stomach after being outside, it is best to schedule a visit to the vet.

Weight loss is another symptom of parasitic infections in cats. Parasites can interfere with digestion and steal vital nutrients from your cat’s body, leading to weight loss.

Poor coat condition may also indicate a parasitic infection. A dull and unkempt coat can be a sign that your cat is not feeling well. Your cat’s coat should be shiny and well-groomed, so paying attention to any changes in its appearance is essential.

Anemia is another symptom of parasitic infections in cats. Fleas and ticks can cause anemia by feeding on your cat’s blood. Anemic cats may feel weak and lethargic.

Lungworms can infect the respiratory system of cats and cause coughing. This symptom can be severe if left untreated.

Lastly, parasitic infections can drain your cat’s energy, leaving them tired and uninterested in their usual activities. This symptom can be distressing for your cat and concerning for you as an owner.

If you observe any of these symptoms in your cat after they have spent time outdoors or eaten prey, take them for a checkup with their veterinarian as soon as possible. Treatment will depend on the type of parasite involved and may include medication or other interventions. Regular deworming and flea and tick prevention are crucial in decreasing the chance of parasitic infections in your cat.

What Happens If My Cat Eats A Earthworm-2

Choking Risk When Eating Earthworms

As a curious and playful creature, it’s not uncommon for cats to find themselves intrigued by earthworms. However, as a responsible pet owner, it’s important to be aware of the potential choking risk associated with this seemingly harmless activity.

The long and wriggly nature of earthworms can pose a significant risk to your cat’s airway. If swallowed whole, an earthworm may become lodged in your cat’s throat, preventing them from breathing normally. This can be a life-threatening situation that requires immediate veterinary attention.

To prevent such an occurrence, it’s best to keep your cat away from areas where earthworms are prevalent, such as gardens or areas with moist soil. Additionally, it’s crucial to regularly inspect your cat’s toys and remove any small or easily breakable parts that could be swallowed.

If you suspect that your cat has swallowed an earthworm or any other object and is experiencing symptoms of choking, such as coughing, gagging, difficulty breathing or swallowing, or pawing at the mouth or throat, seek emergency veterinary care immediately.

Gastrointestinal Upset from Eating Earthworms

Cats are known for their insatiable curiosity and love for exploration, which often leads them to eat things they shouldn’t. One such thing is earthworms. While earthworms are not toxic to cats, they can cause gastrointestinal upset, which can be alarming for cat owners.

The tough outer layer of earthworms is difficult for a cat’s digestive system to break down. As a result, it can cause irritation and inflammation in the stomach and intestines, leading to vomiting, diarrhea, loss of appetite, and lethargy. The severity of these symptoms depends on how much of the earthworm was consumed and the overall health of the cat.

If your cat has eaten an earthworm and is experiencing gastrointestinal upset, it is important to provide supportive care and monitor them closely. You can start by withholding food for a few hours to give their digestive system a rest. Additionally, offer small amounts of water or electrolyte solution to prevent dehydration. Once your cat is able to eat again, provide them with a bland diet such as boiled chicken and rice. This will help soothe their stomach and promote healing.

It’s crucial to seek veterinary care if your cat’s symptoms persist or worsen. Your vet can offer additional treatment options such as medication or fluids to help your cat recover quickly. Prompt attention can prevent severe complications that could result from gastrointestinal upset.

Prevention Tips to Keep Your Cat Safe

Here are five prevention tips that can help:

  • Keep your cat indoors: It’s the easiest way to prevent your cat from coming into contact with earthworms. Not only does it prevent them from eating earthworms, but it also protects them from other potential dangers outside.
  • Check your yard: If you do let your cat outside, make sure you check your yard for any potential hazards, including earthworms. Walk around your yard and check the soil for any signs of earthworms before letting your cat outside.
  • Use natural deterrents: Natural repellents like citrus peels, coffee grounds, and vinegar can be used to keep earthworms away from your yard without harming your cat. These natural remedies are safe and effective in keeping your cat away from potential hazards.
  • Keep your cat on a leash: If you take your cat outside on a leash, it gives you more control over where they go and what they come into contact with. This can help prevent them from eating earthworms or other harmful creatures that may be lurking outside.
  • Monitor your cat’s behavior: It’s important to keep an eye on your cat and look out for any signs that they may have eaten an earthworm. Symptoms like vomiting, diarrhea, lack of appetite, or lethargy should be taken seriously, and you should contact your veterinarian immediately if you notice any of these symptoms.

In addition to these prevention tips, keeping your cat’s litter box clean and providing them with a balanced diet can also help prevent them from seeking out alternative food sources like earthworms. It’s also important to keep your yard and garden free of harmful pesticides or chemicals that could be harmful to your cat if ingested along with an earthworm.

Lastly, make sure to keep all household plants out of reach of your cat. Some plants can contain earthworms or other insects that may be attractive to your feline friend. By keeping these plants out of reach, you can minimize the risk of your cat ingesting any harmful insects or worms.

How to Monitor Your Cat After Eating an Earthworm

Cats are natural hunters and curious creatures, often finding themselves munching on insects or earthworms. Although earthworms are not toxic to cats, they can still pose some potential risks. As a responsible cat owner, it is important to monitor your feline friend closely after they have eaten an earthworm to ensure they remain healthy and happy. Here are five essential tips on how to monitor your cat after eating an earthworm:

Look Out for Vomiting or Diarrhea

Vomiting or diarrhea are common symptoms that may occur after your cat has eaten an earthworm. If your cat appears to be experiencing these symptoms, it is important to keep them hydrated and seek veterinary care if the symptoms persist for more than 24 hours. Dehydration can quickly lead to more severe health problems, so it’s crucial to act fast.

Monitor Appetite and Energy Levels

Keep an eye on your cat’s appetite and energy levels. If your cat seems lethargic or disinterested in food, this may be a sign of illness. Encourage them to drink water and try to entice them with small amounts of food. A lack of appetite can indicate that your cat is feeling unwell, so it’s essential to keep a close watch.

Watch for Signs of Pain

Another important symptom to watch out for is any signs of discomfort or pain. If your cat appears to be in pain, such as vocalizing or avoiding certain movements, this may be a sign of a more serious issue. In this case, it is vital to seek veterinary care immediately. Your veterinarian can perform a thorough examination and determine the best course of action.

Observe Litter Box Habits

Check your cat’s litter box for any changes in their stool, such as diarrhea or constipation. Also, keep track of how often they are using the litter box and if they are able to pass urine normally. Difficulty passing urine can indicate a urinary tract infection or blockage, which can be life-threatening if left untreated.

Keep Your Cat Hydrated

Ensure your cat has access to fresh water at all times. You can also encourage them to drink more water by adding some low-sodium chicken broth to their water bowl. Adequate hydration is essential for maintaining overall health, especially after an episode of vomiting or diarrhea.

When to Contact a Veterinarian

While it may seem harmless, certain situations require us to contact a veterinarian to ensure our cat’s health and safety.

The first and most crucial situation is when your cat has ingested a large number of earthworms or if the earthworms were contaminated with harmful substances. In such cases, prompt medical attention from a veterinarian is necessary to prevent serious complications.

It’s equally important to keep an eye out for symptoms such as vomiting, diarrhea, lethargy, loss of appetite, and dehydration. These symptoms may indicate that your cat has developed an infection or other complications related to the ingestion of earthworms. If you notice any of these symptoms, seek veterinary care right away.

If your cat has a history of health issues or has a weakened immune system, they’re at a higher risk of developing complications from ingesting earthworms. Therefore, it’s vital to contact a veterinarian immediately if they have eaten an earthworm.

While eating earthworms may not always be harmful to your cat in small quantities, it’s better to be safe than sorry. As responsible pet owners, we need to be vigilant about our cats’ health and wellbeing. If you’re unsure or concerned about your cat’s health after they’ve eaten an earthworm, contact a veterinarian. They can properly assess your cat’s condition and provide appropriate treatment and care.


In conclusion, while it may be tempting to let your feline friend explore the great outdoors and indulge in their natural hunting instincts by snacking on earthworms, there are some potential risks that need to be considered. Although earthworms themselves are generally not toxic or harmful to cats, they can carry parasites and toxins that could potentially harm your furry companion. Moreover, consuming too many earthworms or swallowing them whole without proper chewing can cause intestinal blockages.

It’s crucial to keep a close eye on your cat after they’ve eaten an earthworm and watch out for symptoms such as vomiting, diarrhea, lethargy, loss of appetite, and dehydration. If you notice any of these symptoms persisting for more than 24 hours or worsening, it’s best to seek veterinary care immediately.

Prevention is key when it comes to keeping your cat safe from potential hazards associated with eating earthworms.
