Toxoplasmosis is caused by a microscopic cat parasite called Toxoplasma gondii
Feline toxoplasmosis is common worldwide, but most infections cause mild or no illness
Humans most often get toxoplasmosis from undercooked meat or unwashed produce, not directly from cats
Healthy adults and children usually show no symptoms
The highest risk groups are pregnant people and those with weakened immune systems
Good hygiene and litter box management greatly reduce risk
So, what is toxoplasmosis in cats exactly?
Toxoplasmosis is an infection caused by a microscopic parasite called Toxoplasma gondii cats are a natural host for the parasite, which is why the disease is often associated with felines.
Cats typically become infected by:
Eating raw or undercooked meat
Hunting infected prey outdoors
Once infected, a cat with toxoplasmosis will usually carry the parasite for life. However, in most healthy cats, the parasite becomes dormant and causes no ongoing health problems.
Many people believe toxoplasmosis only comes from cats, but this is a common misconception.
The most common transmission routes include:
Eating undercooked or raw meat
Eating unwashed fruits and vegetables
Drinking contaminated water
Handling soil (gardening or sandboxes)
Contact with cat feces that has sat for 1–5 days
Important to know:
Fresh cat feces are not immediately infectious. The parasite needs time to become dangerous, which means daily litter box cleaning significantly reduces risk.
Another important clarification: cats do not continuously spread toxoplasmosis.
Most cats shed the parasite only once
Shedding usually lasts 3–10 days after their first exposure
Indoor cats that don’t hunt or eat raw meat are very unlikely to shed the parasite
This makes well-cared-for indoor cats a low-risk source for most households.
Most cats show no symptoms, but when illness does occur, recognizing cat toxoplasmosis symptoms early is critical.
Toxoplasmosis Symptoms for Cats:
Fever
Weight loss
Lethargy
Loss of appetite
Jaundice
Eye inflammation
Muscle pain
Neurological Signs of Toxoplasmosis in Cats
In more serious cases, especially in kittens or immunocompromised cats, neurological signs of toxoplasmosis in cats may appear:
Tremors
Seizures
Loss of coordination
Kitten Toxoplasmosis Symptoms
Kitten toxoplasmosis symptoms may be more severe and progress faster, making prompt veterinary care essential.
If you notice any signs and symptoms of toxoplasmosis in cats, contact your veterinarian immediately.
Symptoms in Humans
Most healthy people experience no symptoms at all. When symptoms do occur, they often feel similar to the flu:
Body aches
Swollen lymph nodes
Headaches
Fever
Fatigue
The following information does not replace medical advice. If you’re pregnant or planning to become pregnant, always consult your healthcare provider.
If you were infected before pregnancy, your baby is usually protected by immunity
The chance of getting toxoplasmosis for the first time during pregnancy is low
Even if infection occurs during pregnancy, transmission to the baby is estimated at 10–15%
Most babies exposed during pregnancy show no symptoms at birth, though some may develop vision or neurological complications later in life.
If you’re concerned, your doctor or midwife can:
Perform a blood test to detect infection
Recommend additional testing or monitoring if needed
Reduce Infection Risk in Cats
Keep cats indoors whenever possible
Never feed cats raw or undercooked meat
Prevent hunting and scavenging
Schedule regular veterinary checkups
Reduce Transmission to Humans
Scoop the litter box daily
Wear gloves when handling litter or soil
Wash hands thoroughly after litter box cleaning or gardening
Wash fruits and vegetables before eating
Cook the meat until fully done
Extra Precautions for Pregnancy & Young Children
Have someone else clean the litter box during pregnancy
Keep litter boxes inaccessible to babies and toddlers
Cover outdoor sandboxes and play areas
Wash hands before feeding or holding your child
For most healthy children, toxoplasmosis is rarely serious and often causes no symptoms at all.
Children at higher risk include:
Babies exposed before birth
Children with weakened immune systems
When symptoms occur, they may include:
Fever
Sore throat
Swollen lymph glands
Headaches
Muscle aches
Severe cases are uncommon but can affect the eyes or brain, particularly in immunocompromised children.
Will Toxoplasmosis Go Away?
Many pet owners ask, will toxoplasmosis go away? In healthy cats, the infection often becomes inactive and causes no long-term issues, but treatment is still important when symptoms appear.
Treatment for Toxoplasmosis in Cats
Toxoplasmosis in cats treatment typically includes:
Prescription antibiotics (commonly clindamycin)
Supportive care (fluids, nutritional support)
Treatment of secondary infections if present
Early diagnosis improves outcomes, especially for cats showing neurological symptoms.
Yes, toxoplasmosis is generally associated with cats, however, dogs can get it too! This is why we’re always going on about how to keep the dog out of the litter box.
The problem is that because our kitty cats are primary carriers for the parasite, when our doggies go nosing into the litter box, they can easily inhale or ingest contaminated soil.
Other causes of toxoplasmosis in dogs include:
Ingesting contaminated raw meat
Drinking water with the parasite in it
Ingesting infected soil
Toxoplasmosis Symptoms in Dogs:
Fever
Weight loss
Lethargy
Loss of appetite
Jaundice
Inflammation of the eye
Tremors or seizures
Muscle pain
The symptoms of toxoplasmosis in dogs are similar to cats. If you spot any of the following symptoms, make sure to take your pooch to the vet.
Before your baby starts crawling or your toddler begins exploring, it’s important to plan where the litter box is located and how access will be restricted.
Baby gates can help, but they’re often inconvenient — especially for rooms that need frequent access. Closing doors isn’t ideal either, since cats hate closed doors.
Door Buddy offers a simple solution.
The Door Buddy door latch keeps doors open just wide enough for cats to pass through, while blocking babies, toddlers, and dogs from accessing the litter box.
Contact your doctor if you or your child experiences concerning toxoplasmosis symptoms, especially if immunity is compromised.
If your cat shows signs of illness, prompt veterinary care is essential for effective treatment for toxoplasmosis in cats.
Myth: All cats spread toxoplasmosis
Fact: Most indoor cats never shed infectious parasites.
Myth: Toxoplasmosis spreads through cat fur
Fact: Transmission occurs through ingestion, not contact.
So, there you have it - everything you need to know about toxoplasmosis in cats. Again, if you notice any toxoplasmosis symptoms, you should take your pet to the vet or book an appointment with your doctor.
Even though Toxoplasmosis in cats is a real and scary disease, the infection rarely causes problems in healthy babies, toddlers, or children.
“Fur-tunately”, by taking just a few precautionary measures, you can greatly minimize the risks and therefore allow your child to enjoy the companionship and friendship that your favorite feline provides.
