But this is n’t a cause for affright , say Alisa Hutchison , DVM , MPH , a professor of community medication at theUniversity of Missouri College of Veterinary Medicinein Columbia , Mo. Coccidia do n’t always make disease , she explicate , and there are efficient intervention uncommitted when they do .

Still , the prevalence of these pesky ( and sometimes life - threatening ) parasites highlight the grandness of unconstipated faecal test for your guy .

What Is Coccidia?

Coccidia are single - celled leech called protozoan that infect the intestinal parcel of land of cat . According to Hutchison , there are several different specie of order Coccidia that bear on felines , let in species ofIsospora , Toxoplasma , Hammondia , Besnoitia , Cryptosporidium , andSarcocystis .

Hutchison enounce theIsosporaspecies ( IsosporafelisandIsosporarevolta , also calledCystoisospora spp . ) are by far the most uncouth in African tea . They ’re also mintage - specific . This means , for lesson , that dogs can not get taint with the twoIsosporaspecies that taint cats . And thankfully , humans ca n’t either . However , Hutchison notes that some of the other coccidia species ( likeToxoplasma gondii ) are potentially zoonotic ( which mean they can be passed from deary to people ) .

How Do Cats Get Coccidia?

Infected cats shed an immature form of coccidia ( called oocysts ) in their poop . After a short period of prison term , these oocysts become sporulated , or infective . salubrious computerized axial tomography become infected with order Coccidia when they eat up soil or other contaminated things in their surround that contain these sporulated oocysts . This can well go on when grooming their fur and paws .

Cats can also get coccidia by eat infected medium host of the sponge , include shiner , rats , cricket , and cockroaches .

Signs and Symptoms of Coccidiosis in Cats

Not every true cat with order Coccidia will have mansion of infection or disease . When illness does occur , it ’s cry coccidiosis and is most often see in new kittens and in sometime cats with dampen resistant system .

According to Hutchison , the most vulgar signs of disease due to coccidia are naturally related to the digestive organisation ( where the sponge be ) and include :

Hutchison adds that cats with severe disease can exhibit anorexia , vomiting , and mental dullness , and they can ultimately die because of complications from the disease .

Because these signs are n’t specific to coccidiosis and are associated with a wide chain of illnesses , fecal exam — during which veterinarian await for oocysts under a microscope — are essential to create a determinate diagnosis .

Coccidia Treatment in Cats

Not every African tea infected with coccidia will require treatment . Many are able to eliminate the parasite on their own .

" If coccidia is identified on a fecal examination and the cat does n’t have clinical signaling , it may be most effectual to use an easy digestible dieting and probiotic flora to help balance the gut microbiome and then recheck the feces by and by , " Hutchison excuse . " But if there are clinical signs , it ’s a full theme to treat . " She adds that , in multi - cat households , if one feline is diagnosed with coccidiosis , all cats in the home should undergo treatment as well .

Hutchison notes that there is presently only one approved intervention for coccidiosis : anoral antimicrobialcalled sulfadimethoxine . discussion with sulfadimethoxine could last anywhere from a few day to several workweek to ensure that all order Coccidia have been eliminated from your cat ’s gut . " Several other drug have been tried at various doses with some succeeder , " she adds . " Ponazuril has gained popularity and seems to be a hopeful discourse . Many shelter and catteries are using this drug routinely now in place of the okay sulfadimethoxine . "

Despite sulfadimethoxine ’s success with treating coccidiosis , Hutchison says stool sampling rechecks are of uttermost grandness to see to it the leech are n’t resistant to the discourse . She also observe that some coccidia go into a sorting of remission call premunition , where the resistant organisation is ensure the disease . This , Hutchison explains , may not last , as once the cat is punctuate — such as when a kitty is adopt and movement into a new home — he can once again initiate spill the parasite , become morbific , and/or exhibit clinical sign .

For cats with spartan coccidiosis , extra treatments may be needed . For lesson , mobile therapy would be bespeak for a cat with severe dehydration .

How to Prevent Coccidia Infection

Hutchison tell that environmental control of coccidia is very significant . " Coccidia are hardy and difficult to kill with everyday disinfectant that are dependable for pet , " she explain . The Companion Animal Parasite Councilnotes that infective oocysts can live on as long as one class in sure environments .

If your cat is diagnose with coccidia , Hutchison recommendspromptly cleaning the litter boxafter each intestine movement . You should also steamer or atmospheric pressure wash your cat ’s litter box with the hot potential water every clip you modify the bedding , she says .

It ’s important to note that even asymptomatic cats can shed oocysts in their poop that go on to infect others — or even reinfect themselves . annual faecal exams are a key component part of both detecting and foreclose the spread of this parasite .

Finally , because cats can get order Coccidia by eat sure prey , Hutchison say you should minimize your feline ’s hunting habits . Luckily , there aremany toys availablethat can give your true cat the bang of the hunting without the pain of leech .
