Why do cats gag at smells?

Cats may gag at smells for various reasons. Their highly sensitive olfactory system can become overwhelmed or irritated by certain odors, leading to a gag reflex. It can serve as a natural defense mechanism to protect them from potential dangers or toxic substances in their environment.

Cats can have individual sensitivities to different smells. While it varies from cat to cat, certain common triggers include strong chemicals, cleaning agents, certain plants, or even specific food odors. Understanding your cat’s specific sensitivities can help you avoid exposing them to triggers that cause gagging.

Is gagging a sign of a health issue?

In some cases, repeated or persistent gagging at smells can be an indication of an underlying health issue. Conditions such as oral infections, gastrointestinal problems, or dental diseases can cause a cat’s sense of smell to become hypersensitive, leading to gagging at certain odors. If you notice frequent or concerning gagging episodes, it is advisable to consult a veterinarian for a thorough examination.
