Dial A Vet, why does my cat open its mouth and freeze when sniffing things? Should I be worried?

I've noticed something odd with my cat lately. Whenever she sniffs certain things, like her favorite blanket or her food, she opens her mouth and just freezes in place for a few moments. It's almost like she's in a trance, and it happens a couple of times a day now, which has me feeling quite puzzled and a bit worried. I've tried to distract her or call her name when she does it, but she seems completely absorbed. I'm not sure if this is normal or if I should be doing something about it.

Answer

What you're observing in your cat when she opens her mouth after sniffing something is likely the Flehmen response, a normal feline behavior. It's usually not a cause for concern, but monitoring for any additional symptoms is always a good idea.

  • Normal behavior often seen in cats and some other animals
  • Common when they encounter interesting or strong scents
  • Not typically harmful or indicative of a problem
  • Monitor for any additional unusual behavior

The Flehmen response is a fascinating sensory behavior where the cat uses a special organ called the Jacobson’s organ or vomeronasal organ located on the roof of the mouth. When your cat opens her mouth and "freezes" after sniffing, she's drawing scent particles toward this organ, helping her analyze the world around her more deeply. It’s an important part of how cats communicate and understand their environment. However, if you notice other worrying signs like lethargy, changes in eating, or nasal discharge, it might be time to consider a vet consultation to rule out any potential health issues.
