Cat Coccidiosis: Symptoms, Diagnosis, Treatment & Prevention Guide
Cat Coccidiosis: Symptoms, Diagnosis, Treatment & Prevention Guide
Coccidiosis in cats is a common parasitic disease, particularly in kittens, immunocompromised cats, or senior cats. Coccidia parasites live in the small and large intestines of cats, causing a range of health issues. While coccidiosis is generally not life-threatening, it can lead to severe diarrhea, dehydration, and even death if left untreated.
What is Coccidiosis?
Coccidiosis is an intestinal infection caused by single-celled organisms called "coccidia" (protozoa). In cats, the most common coccidia species are Isospora felis and Isospora rivolta. These parasites live in the epithelial cells of the small and large intestines of cats, feeding on the cells and causing intestinal damage and inflammation.
Causes of Coccidiosis in Cats
There are several ways cats can contract coccidiosis, including:
Ingestion of food or water contaminated with coccidia oocysts: Coccidia oocysts are infectious to other mammals, such as mice. If a mouse ingests oocysts, they form cysts in the mouse's organs, and cats may become infected by eating the infected mouse. Similarly, cats can be infected by consuming contaminated raw pork, beef, lamb, or other meat.
Contact with the feces of an infected cat: Infected cats shed coccidia oocysts in their feces. When feces are excreted, the oocysts do not die, but gradually mature and eventually become infectious mature spores. Healthy cats can become infected by rubbing against or stepping on an infected cat's feces, then ingesting the oocysts during grooming.
Maternal infection: If a mother cat has coccidia, her kittens are also likely to be infected. Kittens are in close contact with their mothers and may be exposed to oocysts even without direct contact with feces, as oocysts can be found on contaminated anal fur. Because kittens have weak immune systems, they are often more severely affected by coccidiosis.
Feral or stray cats: Feral or stray cats have a higher risk of coccidiosis due to their exposure to contaminated soil. Coccidia oocysts can survive in the soil for long periods (up to a year!).
Note! If you accidentally come into contact with soil contaminated with coccidia oocysts, you may inadvertently introduce the infection to your cat.
Symptoms of Coccidiosis in Cats
Some cats infected with coccidia may not exhibit any noticeable symptoms but still shed oocysts and can infect other cats. Kittens and immunocompromised or senior cats are more likely to become infected and develop symptoms. Symptoms of coccidiosis in cats can range from mild to severe:
Mild infection or early stages: Digestive upset, loss of appetite, lethargy, fever, dry nose, feces mixed with mucus and blood.
Severe infection: Persistent diarrhea, severe watery diarrhea, bloody stools, dehydration, weight loss, vomiting, and even death.
After a cat is infected, it can take 7-8 days for symptoms to appear. If a kitten is infected for the first time, it may take about 13 days for symptoms to become apparent.
How to Diagnose Coccidiosis in Cats
Coccidiosis is typically diagnosed by examining a fecal sample under a microscope. Some rare coccidia infections can be diagnosed through specific blood tests.
Treatment for Coccidiosis in Cats
The most commonly used medication for coccidiosis is sulfadimethoxine (50mg/kg daily), a sulfa-based antibiotic. If diarrhea and dehydration occur, additional supportive care may be necessary. For example, cats with mild dehydration can receive oral or subcutaneous fluids. Severely dehydrated cats will need IV fluids to correct water, electrolyte, and acid-base balance. If the cat has severe anemia, blood transfusions may also be necessary.
Can Cat Coccidia Be Transmitted to Humans?
Generally, the most common types of coccidia that infect cats do not infect humans. However, some less common types can be potentially transmissible to humans, such as Cryptosporidium. Cryptosporidium can be transmitted from cats to humans, particularly those with weakened immune systems.
Preventing Coccidiosis in Cats
Preventing coccidiosis in cats involves maintaining good hygiene practices and avoiding exposure to contaminated environments. Here are some preventive measures:
Keep your cat indoors: Indoor cats are less likely to contract coccidiosis.
Do not feed your cat raw meat or let it drink contaminated water: Contaminated raw meat and water can contain coccidia oocysts.
Scoop your cat's litter box frequently and don't let the feces mature: Coccidia oocysts need time to mature after being shed in feces. Removing feces promptly can help reduce the risk of infection.
Wash your hands frequently, clean surfaces, and change your shoes when you come home from outside: This can prevent bringing coccidia oocysts into your home.
Conclusion
Coccidiosis is a common parasitic disease in cats, but with preventive measures and prompt detection and treatment, your cat can remain healthy. If you suspect your cat has coccidiosis, consult your veterinarian immediately for a proper diagnosis and treatment plan.
