Understanding Coccidia in Cats: Symptoms and Treatment Options

Cats are beloved companions, offering affection, entertainment, and comfort to millions of people worldwide. However, like all living creatures, they are susceptible to various health issues, including parasitic infections. One such parasite that commonly affects cats is coccidia. Coccidia are microscopic protozoans that can cause significant discomfort and health problems for our feline friends. In this article, we’ll delve into what coccidia are, the symptoms they can cause in cats, and the available treatment options.

What is Coccidia?

Coccidia are single-celled parasites that belong to the genus Eimeria. They commonly infect the intestinal tract of cats, leading to a condition known as coccidiosis. These parasites are prevalent in environments where cats are in close proximity to one another, such as shelters, catteries, and multi-cat households. Coccidia are transmitted through the ingestion of oocysts, which are the environmentally resistant stages of the parasite’s life cycle. Once ingested, the oocysts release sporozoites, which invade the cells lining the intestinal tract, leading to infection.

Symptoms of Coccidia in Cats

Coccidia infection can manifest with various symptoms, ranging from mild to severe. Some cats may exhibit no symptoms at all, while others may experience significant discomfort. Common symptoms of coccidia in cats include:

  1. Diarrhea: One of the hallmark signs of coccidiosis is diarrhea, which may range from mild to severe. The stool may be watery, contain mucus, and have a foul odor. In some cases, blood may be present in the feces.
  2. Dehydration: Prolonged diarrhea can lead to dehydration in affected cats. Signs of dehydration include lethargy, sunken eyes, dry gums, and decreased skin elasticity.
  3. Weight loss: Cats suffering from coccidiosis may experience weight loss despite maintaining a regular appetite. This is due to the parasite’s impact on nutrient absorption in the intestines.
  4. Lethargy: Infected cats may appear lethargic and lack their usual energy and enthusiasm.
  5. Vomiting: In some cases, cats with coccidiosis may vomit, especially if the infection is severe.
  6. Poor coat condition: A dull, unkempt coat may be indicative of an underlying health issue such as coccidia infection.

It’s essential to note that the severity of symptoms can vary depending on factors such as the cat’s age, overall health, and the level of parasite burden.

Treatment for Coccidia in Cats

If you suspect that your cat has coccidia, it’s crucial to consult your veterinarian for an accurate diagnosis and appropriate treatment. Diagnosis is typically made through a fecal examination to detect the presence of coccidia oocysts.

Treatment for coccidia infection in cats typically involves the administration of specific medications to eliminate the parasites and alleviate symptoms. The most commonly used drugs for treating coccidiosis in cats are sulfadimethoxine and trimethoprim-sulfadiazine. These medications work by inhibiting the growth and reproduction of the parasites, ultimately clearing the infection.

In addition to medication, supportive care may be necessary to help affected cats recover. This may include fluid therapy to address dehydration, nutritional support to maintain energy levels, and monitoring for any complications.

It’s essential to follow your veterinarian’s recommendations regarding the dosage and duration of treatment to ensure effective clearance of the parasite and prevent recurrence.

Coccidia Treatment in Cats

In addition to treating infected cats, it’s essential to take measures to prevent the spread of coccidia and minimize the risk of re-infection. Here are some strategies for managing coccidia in multi-cat environments:

  1. Cleanliness: Regular cleaning and disinfection of litter boxes, feeding bowls, and living areas can help reduce the environmental contamination with coccidia oocysts. Use a pet-safe disinfectant recommended by your veterinarian.
  2. Hygiene: Practice good hygiene practices, such as washing your hands thoroughly after handling cats or cleaning litter boxes, to prevent the transmission of coccidia.
  3. Quarantine: If you have multiple cats and one is diagnosed with coccidia, consider isolating the infected cat to prevent the spread of the parasite to other cats.
  4. Routine veterinary care: Schedule regular check-ups with your veterinarian to monitor your cat’s health and detect any signs of coccidia infection early.

FAQs about Coccidia in Cats

Does coccidia smell in cats?

Coccidia infection itself typically doesn’t have a distinctive odor. However, the diarrhea that often accompanies coccidiosis in cats can sometimes have a foul smell due to the presence of blood, mucus, and digestive disturbances. If you notice unusual odors coming from your cat’s feces, it’s essential to consult your veterinarian for a proper diagnosis and treatment.

Can cats get coccidia?

Yes, cats can get coccidia. Coccidia are single-celled parasites that commonly infect the intestinal tract of cats, particularly kittens and those with weakened immune systems. Cats can become infected with coccidia by ingesting oocysts from contaminated environments, such as soil, water, or feces from infected animals. Multi-cat households, shelters, and catteries are at higher risk for coccidia transmission due to close contact between animals.

How long does it take to rid coccidia in cats?

The duration of treatment to rid coccidia in cats can vary depending on factors such as the severity of the infection, the cat’s overall health, and the effectiveness of the chosen treatment. With appropriate medication and supportive care, coccidia infection in cats can typically be resolved within 1 to 3 weeks. However, it’s essential to follow your veterinarian’s recommendations regarding the dosage and duration of treatment to ensure complete clearance of the parasite and prevent recurrence.

Will coccidia go away on its own?

In some cases, mild coccidia infections in healthy adult cats may resolve on their own without the need for specific treatment. However, it’s essential to monitor your cat closely for any signs of illness, such as diarrhea, lethargy, or weight loss. If your cat is showing symptoms of coccidia infection, it’s best to consult your veterinarian for proper diagnosis and treatment. Even if the infection appears to resolve spontaneously, untreated coccidia can lead to complications and may recur later. Additionally, infected cats can shed coccidia oocysts in their feces, contaminating the environment and potentially infecting other animals. Therefore, it’s crucial to address coccidia infections promptly to prevent further spread and ensure the health and well-being of your cat.


Coccidia infection is a common parasitic disease that can affect cats of all ages, leading to diarrhea, dehydration, weight loss, and other symptoms. Prompt diagnosis and treatment are essential for managing the infection effectively and preventing complications. If you notice any signs of coccidia in your cat, such as diarrhea or lethargy, consult your veterinarian for guidance. With proper treatment and preventive measures, you can help keep your feline companion healthy and happy.
