Intestinal Parasite (Coccidia) in Cats

3 min read

Treatment and Care


Treatment is generally outpatient. A sulfa based parasite medication for cats to kill the parasite will be prescribed, and is generally highly effective and fast working. Your cat will need to be rehydrated as a result of the diarrhea. If your cat is debilitated as a result of severe infection, your veterinarian may suggest observation in a medical setting. A follow up fecal examination within 1-2 weeks of the initial treatment will be needed to ensure that the parasite is no longer present in the body.


Living and Management


You will need to administer the full course of prescribed medication as directed and monitor your cat for progress. If there is a decline in its health, you will need to return to your veterinarian to ensure that there is not a more serious underlying health issue that needs treatment. Keep in mind that hygeine is also an issue. Wearing disposable gloves and disposing of feces properly is critically important.




The best prevention is to keep infected animals apart. Preemptive testing of the feces from your cat while it is pregnant, or after it has given birth, to be sure that it is not infected will help to protect newborns from infection.


New owners may wish to have their kitten's feces tested to ensure that the coccidia parasite is not present, since this is a common issue. If you have a kitten that is infected, alert the breeder or owner to the problem so that treatment can be prescribed for their remaining animals.
