How to Treat Coccidia in Cats

Updated November 21, 2016

Coccidia are single-cell protozoans that can attack a cat's intestinal tract. Coccidia typically are seen in kittens and puppies under the age of 6 months, because their immune systems are not sufficiently developed to fight the continued growth of the protozoans. On the rare occasion when Coccidia are seen in adult cats, it is usually because the animal's immune system is suppressed from either stress or a previous illness or injury. Chronic diarrhoea is a symptom of the presence of Coccidia, which are seldom fatal unless the kitten is very young and the diarrhoea becomes so severe that he's severely dehydrated. Coccidia has an incubation period of 13 days.

Reduce the kitten's stress, which can make a bout of Coccidia worse. Kittens become stressed for a variety of reasons. If you are raising more then one kitten at a time, you may notice that one is more dominate than the other; the dominance can be so bad that your more submissive cat might not be getting enough to eat or feels like it is always being threatened. Some cats are stressed by strangers in your home, young children or loud noises.

Take your kitten to the veterinarian for medication that can treat Coccidia.

Keep your cat hydrated by making sure she always has access to clean water. If your cat is acting a little under the weather and you suspect she is dehydrated, pinch a small portion of skin on her neck. When you release the skin, it should return to its flat position in less then three seconds. If the skin stays pinched, take your cat to the veterinarian for treatment.

Sanitise all your cat's things with a 10 per cent ammonia solution.


Make sure the litter box is kept clean and that your new kitten is kept away from other cats that have been diagnosed with Coccidia. Treating Coccidia can take one to three weeks, depending on the severity of the case.
