Allergiescan range from a mild inconvenience to a serious health risk, but one thing’s for sure—they’re not something to take lightly.

So, when thisRedditoragreed to house-sit for a friend during their vacation, the last thing he expected was for them to casually drop the news that they had just gotten a cat—despite knowing he was allergic. Naturally, he had no choice but to back out.

However, this decision didn’t sit well with his friend, and what started as a simple favor turned into a frustrating standoff.

Up to 20% of adults are allergic to cats

Allergies affect a significant portion of the population—up to30–40% worldwide. Among those, around10–20% of adultsare sensitive to cats, making these furry companions a surprisingly common trigger.

In fact,catsare one of the biggest offenders when it comes to pet-related allergies, being twice as likely as dogs to cause a reaction. And despite what many believe, it’s not their fur that’s to blame. The real trouble comes from proteins found in their saliva, urine, and dander (tiny flakes of skin they shed).

According to theOhio State University College of Veterinary Medicine, these proteins can lead to a variety of uncomfortable symptoms, such as:

For most, these symptoms are more of an annoyance than anything else. But for others, an allergic reaction can escalate into something much more dangerous. Severe cases may result in anaphylaxis, a life-threatening condition that includes swelling, difficulty breathing, and even shock.

While there’s no surefire way to prevent an allergy, there are ways to manage it. Medication or allergy shots, for example, can help reduce reactions. If you’re allergic, it’s still wise to limit your exposure to cats and consult a doctor for personalized advice. Allergies are no joke—stay safe out there!
