Carol F., 76, never imagined the cat pee smell soaked into her rug would almost kill her.
Happily retired, her new passion was spending time with her cat and reading a new book every week. She often entertained guests in her home with Mr. Whiskers… until something terrible happened.
One afternoon, while hosting a book club in her living room—right on her freshly cleaned carpet—Carol noticed a sharp sour smell in the air. She had just scrubbed the area earlier that morning, so she brushed it off as leftover cleaner or her imagination… but then a headache gripped her skull so violently, it felt like her brain was being squeezed dry like a lemon. OUCH! She quickly grabbed a glass of water and some painkillers, but little did she know it was too late…
As she desperately tried to shake off the pounding in her skull, a tightness in her chest squeezed her lungs and— she couldn’t breathe!
She felt the floor beneath her tilt sideways and her vision began to blur. She fell to her knees, crying in pain, too dizzy to even stand.
"The headache was bad," Carol recalls. "But the embarrassment of crying in front of my friends was worse.”
I couldn't stop crying, my skull felt like it was being split open, and my headache got so bad my friends almost called 911.”
A couple of days later, Carol started experiencing shortness of breath, and her lungs felt like they were filled to the brim with water… The headache and dizziness didn’t go away either…
With so many health risks associated with chronic headaches, shortness of breath, and dizziness, Carol decided to see a doctor.
The first thing the doctor asked was if she had a cat because he had seen many patients with similar symptoms. And they all had cats.
The doctor said it was just a bad reaction to the toxic cat pee smell and litter box odors lingering in her home—and especially in soft surfaces like rugs, carpets, and bedding—that luckily it wasn't something more serious.
Carol’s heart sank. “Could it really be that serious?” she asked.
“Absolutely,” the doctor replied. “You’re breathing in ammonia from the cat pee, and if it’s not cleaned properly, it can lead to permanent lung damage and increase your risk of severe respiratory diseases like pneumonia.”
Carol is not alone: 66% of Americans are pet owners, but many don’t realize that the smell from their pet’s pee can severely damage their health.
Even after cleaning the carpet or mopping the floors, the microscopic odorants can remain in the air for weeks—or even months—after the accident. These particles cling to nearly every nook and corner of your home, especially soft surfaces like carpets, rugs, couch cushions, and bedding.
What you need to know is… Cat pee contains toxic uric acid crystals that release ammonia, which is a chemical that can linger in your air for years and can cause lung diseases like pneumonia, constant respiratory problems, headaches, and chest pain, if not cleaned properly.
And that’s not the worst part: continuous inhalation of ammonia can lead to irreversible damage to lung tissue, resulting in increase risk of pneumonia and increased susceptibility to more respiratory infections.
Her doctor also said that… actually, she likely didn’t notice her cat’s pee smell until it started damaging her health because she had developed olfactory fatigue, also known as nose-blindness. When the human nose gets used to certain smells, it starts “forgetting” to detect them.
In fact, since Americans spend 90% of their time indoors… significant exposure to cat pee smell and ammonia can also increase the risk of asthma by up to 5 times.
"Unfortunately for me, it took years of suffering to finally make me realize how sinister the ammonia cat pee smell can be. It wasn't just the discomfort from the chest pain and lung-crushing coughing fits, it was the thought of losing my one joy left in life - spending time with friends, family, and of course… Mr. Whiskers."
“I wish I had known about the threat of ammonia sooner…”
Carol knew she had to do something to get rid of the ammonia and cat pee smell floating through her home’s air—especially after realizing that no amount of scrubbing, vacuuming, or carpet shampoo could fix what was lingering in the air.
"That's when the real nightmare began," Carol said. "I called a cleaning service and they wanted to charge £450 just for one treatment! Way out of my budget.
“So I went to the store and purchased those air fresheners, what a waste of money. Within two weeks, they'd completely stopped working and when they did they only helped a little. They only temporarily masked the ammonia cat pee smell, they didn’t directly eliminate the root cause of my problem…”
Running out of options, Carol had a tough choice to make: spend a fortune deep cleaning her home, or give up her beloved cat Mr. Whiskers.
