Separating Myth from Reality Regarding Toxoplasmosis & Cats
Toxoplasmosis is one of the most misunderstood topics in companion-animal welfare. For decades, cats have been unfairly blamed for a disease that is far more commonly transmitted through food and the environment than through living with a beloved pet.
As a rescue organisation, we hear these fears often especially from people considering fostering or adopting cats. This blog aims to set the record straight with clear, evidence-based information.
What Is Toxoplasmosis?
Toxoplasmosis is an infection caused by the parasite Toxoplasma gondii. It is extremely common worldwide, and most healthy people who become infected never experience symptoms. Many don’t even realise they’ve had it.
Humans can become infected in three main ways:
Eating undercooked or contaminated meat (especially pork, lamb, and venison).
Handling or ingesting contaminated soil (gardening, unwashed vegetables).
Rarely, through cat faeces, if a person accidentally ingests oocysts after cleaning an infected cat’s litter tray.
That last point is where many myths begin but it’s also the least likely route of transmission.
Do Cats Really Spread Toxoplasmosis?
Here’s the part most people don’t know:
Cats can only shed the infectious stage of the parasite (oocysts) for 1–2 weeks in their entire life, usually when they are very young.
A cat must eat raw meat or prey to become infected.
Adult indoor cats fed commercial food almost never shed toxoplasma.
Even if oocysts are present in litter, they take 24 hours to become infectious, so daily cleaning eliminates risk.
In short: living with a cat is not a meaningful risk factor for toxoplasmosis, according to global public-health authorities.
Who Should Be Cautious?
Pregnant people and those with weakened immune systems should take simple, sensible precautions not because cats are dangerous, but because toxoplasmosis from any source is more serious for them.
Recommended precautions include:
Avoiding litter box cleaning if possible (or using gloves and washing hands afterwards).
Keeping cats indoors and feeding them cooked/commercial food.
Washing hands after gardening.
Avoiding undercooked meats.
It is worth emphasising again: foodborne transmission is the leading cause of toxoplasmosis. Cats are a minor contributor.
Why This Matters for Rescue Cats
Misinformation about toxoplasmosis leads to fear, surrender, and discrimination against cats especially in countries where community cats already face hostility and abandonment.
For rescues and shelters, this myth can mean:
Pregnant adopters avoiding cats unnecessarily
Foster carers worrying about unfounded health risks
Public misunderstanding used to justify anti-cat policies or cruelty
By educating our community, we protect cats from stigma and ensure they can find the loving homes they deserve.
How to Stay Safe (and Keep Your Cat Safe)
The good news is that prevention is simple:
Scoop litter daily and wash hands after.
Feed cooked or commercial food never raw meat.
Keep cats indoors to prevent hunting and infection.
Wear gloves for gardening and wash fruits and vegetables.
Cook meat thoroughly.
These steps protect both humans and cats and they’re easy.
The Bottom Line
Cats have been unfairly accused of spreading toxoplasmosis for decades, but science tells a different story: the real risks come from food and soil, not from the cat curled up on your sofa.
For foster carers, adopters, and animal advocates, the message is clear:
It is safe to share your home with a cat.
Good hygiene and simple precautions are all that’s needed no fear, no stigma, no surrendering beloved pets.
