What is Coccidia?
Most cats will come in contact with coccidia sometime in their life. The majority of adult cats are immune to the infectious disease that coccidia can cause, called “coccidiosis”. Kittens under six months of age and cats suffering from conditions that hinder their immune system may contract coccidiosis. This rare infection can cause serious effects and, in extreme cases, may even be fatal. Kittens who are infected with coccidiosis are contagious and can infect the rest of the litter. The most common parasite to cause coccidiosis in cats is Isospora  felis. Veterinary attention is needed to ease symptoms and rid the cat of the parasitic infestation.
Coccidia are a group of single-celled parasites called “protozoa”. Cats are susceptible to infection from a number of these parasites, including Isospora, Toxoplasma, Sarcocystis, Besnoitia and Hammondia. Coccidia lodge in the intestinal wall and form cysts. Some of these protozoa require more than one host to complete their development. Once inside the body, it can take up to two weeks for the parasites to mature and begin to reproduce. Coccidia are found throughout the world.

Symptoms of Coccidia in Cats
Kittens may start to show symptoms of coccidiosis from the ages of two weeks to six months. The stress of the weaning process can leave a kitten vulnerable to developing a parasitic infection. Signs to watch for are as follows:
  • Watery diarrhea (may contain blood)
  • Vomiting
  • Anorexia
  • Weight loss
  • Dehydration
  • Abdominal pain
  • Uveitis (inflammation of the uvea)
Causes of Coccidia in Cats
To become infected with coccidia, a cat must come into direct contact with the parasite. Kittens are often exposed to the protozoa from their mother's feces (as adult cats often contain the parasites without showing any symptoms). All known causes of parasite exposure are listed below.
  • Direct contact with infected feces
  • Hunting and eating rodents that contain protozoa in its resting stages
  • Ingesting contaminated soil
Susceptibility is increased in cats with immune deficiencies or who are experiencing stress.
Diagnosis of Coccidia in Cats
If your cat or kitten begins to exhibit any of the symptoms of coccidiosis, bring it to a veterinary clinic or animal hospital immediately. Be prepared to provide the cat's full medical history, especially if it is an adult cat with immune system issues. The veterinarian will perform a complete physical examination of the cat, watching for known signs of coccidiosis. 
The most common way to diagnose a parasitic infection in a cat is by taking a sample of the cat's feces and sending it for microscopic examination. During this examination, larval or adult coccidia may be identified. As these protozoa are exceptionally small, if a microscopic examination comes back negative, there is no guarantee that your cat or kitten is not infected. Blood work will be run, including a complete blood count and a biochemical profile to assess the cat's overall condition. Certain parasites may also be identified via blood smears. If the infected cat is an adult, feline viruses that negatively affect the immune system, such as feline immunodeficiency virus and feline leukemia virus, should be tested for. 
Treatment of Coccidia in Cats
In some kittens or adult cats, coccidiosis may spontaneously go away on its own. In severe cases, both symptomatic and causative treatments may be needed.
Antibiotics 
A course of antibiotics such as Sulfadimethoxine, Trimethoprim-Sulfonamide or Amprolium can stop the coccidia from reproducing. Up to two weeks of oral administration is needed.
Supportive Care 
If the infected cat has become severely dehydrated, hospitalization and intravenous fluids may be needed to stabilize its condition.

Recovery of Coccidia in Cats
Be sure to isolate your adult cat or kitten from other cats during antibiotic treatment. Reinfection can easily happen, so extra sanitation measures should be taken. Clean all litter boxes at least once a day. Most coccidia need at least 24 hours outside of a host to infect another animal, so removing feces from the litter daily can prevent the parasites from re-entering your cat. Disinfect the litter boxes weekly using hot water and bleach. 
Take extra care when monitoring the health of kittens to identify cases of coccidiosis before the infection has progressed too far. Test any pregnant cats for protozoa so that kittens may be treated after birth. Most coccidia can not spread to humans. The most common coccidia, I. felis poses no threat to owners. Infections of Toxoplasma or Cryptosporidium may present a small risk to pregnant women and any human who has a suppressed immune system.

My pet has the following symptoms:
Diarrhea
Vomiting
I recently (3 days ago) adopted 2 kittens from a shelter, one had been treated for coccidia. When I brought her home, she was still having diarrhea and has thrown up twice. My vet gave me a prescription for the diarrhea, but now my second cat has diarrhea and he has thrown up as well. Should I go back to the vet with my second cat? I have also been feeding them wet food once a day, they have free access to their dry food from an automatic feeder. Their throw up looks like they are just throwing up the wet food, should I stop giving the wet food and see if that’s why they are getting sick? Not sure what is wrong with them.

Diarrhoea in your other cat may be due to a variety of causes including Coccidia, other parasites, infections, stress (new cat in the house), diet among other causes; try to feed a dry food only diet for a day or two to see if there is any improvement and ensure that you’re practicing good hygiene cleaning up faecal material and wiping the affected cat’s anus after each litter tray visit. If there is no improvement you should visit your Veterinarian for a check to be on the safe side. Regards Dr Callum Turner DVM

My pet has the following symptoms:
Loose Bowel Movements
I have a rescue kitten that was diagnosed by my vet with coccidia. We treated her with Albon for 14 days. Went back for a recheck and she tested negative so I was told that it was ok to let her mingle with my other 2 cats. It has been 1 week and her stools are still about the consistency of toothpaste. As of yesterday, she has been missing the litter box. We found several small drops of poop on the floor and some were tinged with blood. During the treatment period, I scooped her litter box every couple of hours and steam mopped the floor 2 times a day. Washed all the bedding morning and night with Ammonia. Could she be reinfected or is it possible that this is because she has been eating some of the other cats wet food and maybe it was too much for her tummy? Note that when she was being treated, she never had any accidents outside of the litter box. So sorry for the length of this post. I am just worried to death because now I feel like my whole house may be contaminated. She is still eating, drinking and playing but really sneezing a lot.

It is possible that Lulu may have been reinfected, or the wet food may have caused this soft stool. It might be a good idea to have another stool sample tested, and then possibly put her on probiotics if the stool sample is negative, as the intestine can take a while to heal after some insults. Given the level of cleaning that you are doing, I highly doubt that your house is contaminated.

My pet has the following symptoms:
Blood In Urine
Fostering a new kitten that we are hoping to adopt once she is old enough to be spade. Took her to the vet even though we had to pay out of pocket as foster family because we had lost our last cat to chronic bladder issues. She is 3 months old and they said that not only did she have round worms for also coccidia. They treated her on site with a pill to kill the roundworms and gave us a liquid medicine to treat for 10 days for the coccidia. She is eating well, drinking well, and using the litter box but today we started seeing blood in her urine and she is actually peeing in the bathtub instead of her litter box. Could the blood be from her body fighting these parasites, our vet is not in office for another 36 hours and having lost a cat to "bleeding issues" may blood pressure is up and I am seriously worried now that she may be sicker than we knew. Is there any advise for support that you can offer. I fully intend to carry her back to the vet as soon as I can to discuss this issue but if there is anything that can be done tonight I feel like I need to do it. I have never had an animal with these issues before. I have removed the feces each time as soon as she has gone ( we use the pellet litter). Do I need to do something different until she is well? Thi is my second question. Thanks, bandmom#catluvr

Blood in the urine is sometimes a sign of a bladder infection, and since she is eating and drinking normally, that may be what is going on. Cats will often urinate in strange places when they have an irritation with their bladders, and that may be why she is urinating in the bathtub. As long as she continues to act normally otherwise, you should be fine to have her seen on Monday morning when your clinic opens. If she becomes lethargic, or stops eating, or seems in great distress when she urinates, it would be better so have her seen sooner, at a 24 hour facility. There is not much that you can do at home while waiting other than increasing her water consumption, and if she isn't eating canned food now, you can offer her a canned version of the food that she is eating to get more water into her.

My pet has the following symptoms:
Diarrhea
Sneezing
Lethargic
Runny Nose
Watery Eyes
Red Eyes,
My kitten, who’s four months old, got tested for coccidia but the test had came back negative. But the vet is treating her for coccidia because she has all the symptoms. She is now on her second treatment of Albon 125 mg and as with the first round, she seems to feel better but towards the last 2 or 3 days of a 8 day cycle she takes a turn.

Parasites can be persistent in kittens, and they don't show up on every fecal exam. She may need repeated fecal tests to make sure that she is free of parasites. Probiotics may help as well to help re-establish the good bacteria in her colon.

My pet has the following symptoms:
Lethargy, Vomit, No Play, Sleeping
Hello, I just rescued a 14 week kitten (weighing only 1.1 kg). She is lethargic, shows zero signs of wanting to play (with different types of small toys), will not climb cat tree, tunnel, does not scratch. She also isn't eating enough food, but she does drink quite a bit of water (dehydrated?). She was treated with Baycox for coccidia 6.5 weeks ago. She was also treated for URI and given Ciloxan, Clavamox and tetracycline-T just 4 weeks ago (you can still hear her "crackle" breathing). She was checked by the Animal Shelter's veterinarian and I was told the sound is residual coming from nasal area. She vomited up her food while at the shelter yesterday, and again she vomited this evening after feeding her. I was sent home with some fortaflora and a white powdered medication (1/4 tsp, twice daily) to put in her food. All she will do is sleep on my lap. Just sleep and follow me around the apartment. No play, no exploring, no running. I'm worried. I have only a 7-day guarantee with the shelter, which is not enough time to discover if she will improve in my home. I called a second veterinarian and she told me that my kitten should be looked at again. Should I expect improvement in a couple of weeks? Is her lethargy due to coccidia (even after 6.5 weeks)? Should I give her back for further treatment and/or perhaps adopt another cat? Physically, she is extremely fragile, bony, even anorexic given her age and weight. I'm heartbroken. I feel like the shelter is not a safe place, and I'm wary about adopting another cat from their colony. Is that a valid concern? I'm taking her back to the shelter for another vet check in 2 days' time. Would you be able to respond by then?

Without examining Catie it is very difficult to weigh in on whether there is another underlying cause and if any other further treatment is needed; you should see improvement if the correct treatment and management is being given but I cannot give you any solid assurances. You should visit the shelter Veterinarian again, however it is down to you whether or not you keep this kitten or choose another. Regards Dr Callum Turner DVM

My pet has the following symptoms:
Weakness
Vomiting
Loss Of Appetite
Liquid Mucuos Stool
My three months old kitten, dewormed and vaccinated, was full of energy. And she had a very bad habit of playing near litters of other adult cats of the house. All of a sudden, she stopped eating. We tried to give her food she loved, but they were all denied. The next day she started puking and it contained thin long worms in it. I called my vet, she suggested that I give her a mild dose of homeopathy drug to deworm further. I administered the drug, the vomiting stopped. The next day she was passing mucous stool with foul smell. Was also staying isolated and not eating at all. The next day to the vet's chamber, she diagnosed her with coccidiosis. She was given intravenous saline along with antibiotics. This is today. We are waiting this night, praying that she feels better by tomorrow. But the poor baby is in pain,passing liquid stool unconsciously and can barely stand. She is a gorgeous baby, but not she has a sunken and sad look. I just want her to survive this crisis!! Please pray for her!
