My cat just started smelling around with its mouth open. Is this normal behavior?

This afternoon, I noticed my cat going around the living room, sniffing with her mouth open, almost like she's trying to catch a scent in a funny way. I haven’t seen her do this before, and it seems odd compared to her usual sniffing around. Is this normal behavior for cats, or should I be looking out for something unusual?

Answer

Your cat's behavior of sniffing with her mouth open, known as the "Flehmen response," is typically normal and is how cats gather more information from a scent.

  • This is a common feline behavior for exploring scents.
  • It's especially prevalent when they're interested in a particular scent.
  • Monitor for any additional symptoms indicating concern.

Cats use the Flehmen response to analyze scents in a more detailed manner, often using it when encountering new or intriguing smells. This behavior is completely natural and usually not a cause for concern unless accompanied by other worrying symptoms.
