Product Details

Incident Overview

On January 30, 2026, a consumer purchased a Feliway Classic Starter Kit on Ebay and plugged it in to help calm their cats. The product is designed to release synthetic pheromones intended to reduce stress in felines. Shortly after use, the consumer began experiencing severe symptoms, including a massive headache that did not respond to treatment, dizziness, nausea, and vision problems. The consumer sought medical care and was prescribed methylprednisolone, which provided no relief.

The consumer did not immediately connect their illness to the diffuser. However, when the product ran out on February 17, 2026, their symptoms began to improve rapidly, though they reported not being fully recovered at the time of filing. The consumer noted that the product’s labeling states it is safe for humans. After researching online, the consumer found numerous other users reporting similar issues, including migraines and respiratory problems. The incident report, filed with the CPSC SaferProducts.gov database (Report ID 5908335), describes the product as having a warning defect, indicating a lack of adequate safety information for human users.

Safety Concerns

Immediate Dangers: The diffuser emits a chemical vapor that, according to the reported incident, can cause acute symptoms such as severe headache, dizziness, nausea, and vision disturbances. These effects can be debilitating and may interfere with daily activities or driving.

Long-Term Risks: Continuous exposure to the diffuser's emissions, as experienced by the consumer over approximately 18 days, may lead to prolonged or worsening symptoms. The consumer's improvement after removal suggests that cumulative exposure could result in chronic health issues if not addressed.

Who Might Be Affected: While the product is intended for cats, the diffuser operates in shared indoor spaces, exposing all occupants—including humans and other pets—to the vapor. Individuals with respiratory conditions, chemical sensitivities, or compromised immune systems may be particularly vulnerable.

Warning Signs: Consumers should be alert to the onset of headache, dizziness, nausea, or vision changes after using the product. The absence of immediate symptoms does not rule out a reaction, as the consumer's symptoms developed over time and worsened with continued use.
