Protect Your Pet From the Silent Killer

- ✓ See Danger at 0 PPM: Not 70 PPM like standard detectors that go silent while your pet is still breathing it
- ✓ Plug & Protect: No ladder, no tools, no electrician. 30 seconds to install.
- ✓ Built for the One Who Can't Leave: Your pet can't open the front door. Pet Protector watches the air so they don't have to.
"I read how CO poisoning in pets gets written off as 'unexplained illness.' I went cold. My cat Margo had been lethargic all the previous winter. My vet called it 'age-related decline.' She's 7. I'll never know for sure. I ordered Pet Protector that night. Now I check that '0' before work and exhale."— Lauren H., 38 · Austin, TX · Cat Mom · Verified Customer
Don't Let Your Pet Become a Headline.
Carbon monoxide is the #1 cause of accidental poisoning deaths for pets.
Every year, over 1,000 pets die from CO poisoning, most of them while sleeping. The tragedy? Almost every owner had a "working" detector on their wall. Green light glowing. Silent.
CO comes from furnaces, water heaters, garages, stoves. You can't smell it. You can't see it.
Your pet just doesn't wake up.
Every Breath Your Pet Takes Counts. Standard Detectors Wait. Pet Protector Doesn't.

Meet the Pet Parents Who Stopped Hoping and Started Knowing
"I Saw 22 PPM. My Old Detector Never Beeped."
"We had a 'working' detector for four years. Tested it every six months. Green light. Then I got Pet Protector for our two dogs. Second day: 22 PPM where they sleep all day. My old detector? Still glowing green. Still silent. HVAC found a cracked heat exchanger. I don't let myself think about how long they'd been in that."Labrador & Beagle Dad
"My Vet Mentioned It. I Ordered That Night."
"My vet told me standard detectors aren't calibrated for pets, that by the time they alarm, a small animal has already been symptomatic for hours. I ordered Pet Protector that night. Two months later: 14 PPM. Slow stove leak. Milo was home alone all week while I was at work. I still can't think about it too long."Tuxedo Cat Mom
"I Sent One to My Mom's House"
"My mom is 78. Lives alone with her two dogs. Her old detector was nine years old, the sensor was dead but the green light was still glowing. I sent her a Pet Protector 4-Pack. Now when I call her she tells me the screen reading before she tells me how the dogs are sleeping. '0 and 0, sweetheart.' Best three words I've ever heard."Verified Customer

"It Caught What My $250 Nest Couldn't"
"Nest Protect in every room. Top of the line. Pet Protector showed 31 PPM in the kitchen first week. The Nest? Green. Silent. Cracked burner seal. My cat Theo is in that kitchen every single day. I don't run the 'what ifs' on that one too long."Persian Cat Mom
"I Checked the Camera Every Day. It Showed Me Nothing."
"I'd open the app on my lunch break and see Rosie lying on the couch. Just napping, I thought. She'd been lethargic for weeks, not eating well, low energy. I almost wrote it off as age. My vet mentioned CO misdiagnosis. I ordered Pet Protector that night. It alarmed at 19 PPM two weeks later. Water heater flue, partially blocked. She was home alone every single day that week. I've cried about it more than once."Cavalier King Charles Mom
"I Lost a Pet Once. I Will Never Wonder Again."
"My dog Max died two years ago from what the vet called 'sudden organ failure.' We never got a clear answer. After reading about CO misdiagnosis, how the symptoms match, how pulse oximetry can't detect it, I've spent time I won't get back thinking about that winter. I have Pet Protector in every room of my house now."Two-Dog Household
"Four Dogs. Four Monitors. Zero Worry."
"After learning that standard detectors alarm at 70 PPM, and that smaller dogs succumb faster than humans under the same exposure, I put a unit on every level of the house. The 0 on that screen every morning is the only thing that actually lets me focus at work."Verified Customer
"26 PPM. Old Detector? You Already Know."
"Living room where our dogs sleep. Four days after installing: 26 PPM. My husband said 'the old detector is still showing green.' Gas company found a loose furnace fitting. Three dogs sleep in that room every night. Pet Protector is the reason they still do."Three-Dog Household
Questions From Pet Parents
Most CO detectors only show a green light, which stays on even when the sensor has expired. They don't alarm until 70 PPM, which is after hours of exposure for a small animal. Pet Protector shows you real-time PPM levels on a digital display, starting at 0, and alarms at 10 PPM. You see the actual number in your home every second. Not a light that implies safety, a reading that proves it.
The honest answer: no one knows how many pets it kills, and that's the real problem. Veterinary researchers describe CO poisoning in pets as having "unknown incidence" because the symptoms (lethargy, vomiting, loss of appetite, weakness) are clinically identical to aging, GI illness, and kidney disease. Standard pulse oximetry cannot detect carboxyhemoglobin. The definitive test is rarely ordered. Pets die. The cause is recorded as something else. We're not here to frighten you. We're here to replace fear with a number on a screen.
So did the pets of every owner who found a problem after installing Pet Protector. CO builds slowly, from a cracked heat exchanger, a blocked furnace flue, a loose gas fitting. It accumulates over days at levels that trigger no alarm and produce symptoms so gradual they read as something else. "She's just getting older." "He's had an off week." The absence of a visible problem is not the same as the presence of actual safety.
No. Pet Protector uses professional-grade electrochemical sensors that distinguish between brief cooking fluctuations and sustained CO or gas accumulation. Normal cooking will not trigger an alarm. If elevated readings do appear during cooking, it's a ventilation issue, and knowing that is useful information.
Both. Pet Protector has dual sensors, one for carbon monoxide, one for natural gas including propane. One unit, two threats, one screen. Most standard detectors from the hardware store only detect CO. Pet Protector catches both, with real-time PPM readings starting at 0.
Prioritize the rooms where your pet spends the most time, especially when home alone. Near furnaces, water heaters, and gas appliances. On every level of the home if possible. The 4-Pack covers most homes completely. The first unit should go wherever your pet sleeps when you're gone.
This is exactly who Pet Protector was designed for. Your pet cannot recognize danger, relocate to fresh air, or call for help. Pet Protector monitors the air continuously, every second, all day, and alarms at 10 PPM, long before exposure reaches levels dangerous for small animals. The goal is that you come home to a 0 every day. And on the day that number changes, you find out while there's still time to act.
Plug it into any standard wall outlet. Working in 30 seconds. No tools, no ladder, no electrician, no batteries, no app required.
You're covered by the 90-Day "Breathe Easy" Guarantee, full refund for any reason, no questions asked. Plus a Lifetime Guarantee: if anything ever goes wrong with the device, we replace it free.
