Causes & How to Treat Abscesses in Cats

Let’s be real—no one likes talking about poop. But if you share your home with a cat, it’s a conversation worth having—because buried in that litter box might be something more dangerous than just a bad smell: a microscopic parasite called Toxoplasma gondii.

Yep, you heard that right. Not every cat carries it, and not every pile of poop is infected, but some are, and that “some” is enough to raise concern.

The Science Behind the Stink

Toxoplasma gondii is a sneaky little parasite that lives in many animals, but cats—especially outdoor ones—are its favorite hosts. When a cat eats a rodent or bird carrying the parasite, T. gondii can set up shop in their body and eventually make its way out… through their poop.

Inside the feces, the parasite turns into tough, infectious particles called oocysts. These things are stubborn. Just one oocyst can infect a human, and they can survive in moist soil for up to 18 months. That’s not a typo—eighteen months.

Outdoor cats are the biggest culprits, but even indoor cats that sneak in raw meat or hunt bugs can become carriers.

Why Should You Worry?

For most healthy people, getting infected with T. gondii doesn’t feel like much—maybe a light fever, fatigue, or swollen lymph nodes. You might not even know you’ve had it. But for those with weakened immune systems (like people with HIV/AIDS) or pregnant women, it’s a different story.

In pregnant women, the parasite can pass to the unborn child. This is where it gets scary:

• Miscarriage or stillbirth

• Brain and eye damage in newborns

• Seizures

• Jaundice

• Intellectual disabilities or schizophrenia later in life

That’s why doctors often advise pregnant women to steer clear of litter boxes entirely.

And What About the Smell?

Toxoplasma isn’t the only thing hiding in a neglected litter box. Cat urine contains ammonia, and when that builds up, it can turn your living space into a toxic cloud.

Ammonia fumes can:

• Irritate your lungs and airways

• Cause dizziness and nausea

• Affect both humans and cats, especially in small or poorly ventilated rooms

So yes, cleaning your cat’s bathroom isn’t just about keeping your home tidy—it’s also about health and safety.

So, How Dangerous Is It Really?

Believe it or not, over 60 million people in the U.S. are estimated to carry Toxoplasma gondii. But in most of them, it just chills out quietly in the background, never causing issues.

If you’re healthy and not pregnant, you're unlikely to suffer serious effects. But that doesn't mean you should ignore it. Think of it like leaving raw chicken on your kitchen counter—not always a problem, but not worth the risk.

Here’s What You Can Do

If you’re wondering how to keep your home safe and your cat healthy, here’s a simple checklist:

🛑 Avoid raw diets: Stick to commercial cat food—dry or wet. Skip the raw meat, no matter how “natural” it sounds.
🏠 Keep your cat indoors: Indoor cats are far less likely to get infected.
🧤 Gear up to scoop: Use gloves and a mask when cleaning the litter box. Wash your hands—and even your feet if litter gets scattered around.
🧹 Clean smart: Scoop daily, change litter regularly, and mop up stray granules.
🚫 Don’t dump cat waste in rivers or drains: It pollutes the water and harms wildlife.
🧼 Disinfect often: Keep the box and surrounding area as clean as possible.

Final Thoughts from a Fellow Cat Lover

Look—I’m not a vet, and I’m definitely not a doctor. What I am is a cautious cat owner who’s spent more time than I care to admit reading about feline parasites on late-night internet deep-dives.

This isn’t meant to scare you off cats (they’re awesome). It’s meant to remind us that with every purr and head-bonk comes a little responsibility—like keeping that litter box clean and knowing the risks that come with it.

And if you’re pregnant, immunocompromised, or just unsure? Talk to a doctor or vet. They’ll give you advice that fits your situation and your cat.

If you know more about this topic or have better tips, feel free to share! I’m always happy to update and learn alongside other cat parents.

Stay safe—and scoop smart. 🐾
