Why does a cat have to gasp when it smells something?

Why does a cat have to gasp when it smells something?

Many people have seen cats make a startled face, gasping still after sniffing something, whether it's peeing another cat, the owner's clothes, or something new in the house. This gesture does not mean foul, but a behavior called Flehmen response.

Behind this gesture is a special organ called the Jacobson's organ or Vomeronasal organ (VNO), located in the upper palate area of the cat. This organ does not serve as a common olfactory receptor as the nose, but is specifically designed to receive "pheromones."

A pheromone is a chemical used by animals to communicate with each other, such as territory, identification, reproductive status, or even stress. When a cat encounters a smell with important information, it lifts its upper lip slightly, gasping to help pull the odor molecules directly into this organ, like it is opening an advanced analytical mode.

In other words, while humans use their eyes to obtain information, cats have a much more complex "read news from smell" system than we thought.

The next time you see a cat wandering, don't laugh, because that's probably the time it's processing important information about its small world. 🐾

... Read moreจากประสบการณ์ที่ผมเลี้ยงแมวมา หลายครั้งที่เห็นแมวของผมอ้าปากค้างนิ่ง ๆ หลังจากได้กลิ่นอะไรบางอย่าง เช่น กลิ่นของแมวตัวอื่นในบ้านหรือกลิ่นของวัตถุใหม่ที่นำเข้ามาในบ้าน ผมเริ่มสังเกตว่าไม่ใช่แค่ท่าทางตื่นตกใจเหมือนที่หลายคนเข้าใจ นี่คือการแสดงออกของพฤติกรรม Flehmen response ที่เกี่ยวข้องกับอวัยวะ Jacobson’s organ ซึ่งแมวใช้ในการรับรู้สารเคมีฟีโรโมนที่ช่วยส่งสารสำคัญเกี่ยวกับสถานะต่าง ๆ ของสัตว์ เช่น อาณาเขต การสืบพันธุ์ หรือแม้แต่ความเครียด สิ่งที่ผมคิดว่าน่าสนใจคือการที่แมวจะอ้าปากค้างเล็กน้อยและยกริมฝีปากบนขึ้น เพื่อช่วยนำกลิ่นเข้าสู่อวัยวะนี้โดยตรง คล้ายกับการเปิดโหมดวิเคราะห์กลิ่นระดับลึก ที่ไม่ใช่แค่ดมกลิ่นธรรมดาผ่านจมูกเท่านั้น การเข้าใจพฤติกรรมนี้ช่วยให้ผมมองเห็นโลกของแมวในมุมที่ต่างออกไป เพราะแมวใช้ระบบรับรู้กลิ่นที่พิเศษและซับซ้อนในการสื่อสารและประเมินสภาพแวดล้อมของมัน ผมแนะนำให้คนเลี้ยงแมวไม่ควรตีความผิดเวลาที่เห็นแมวอ้าปากค้าง เพราะนั่นไม่ใช่ความหมายว่าแมวเจอกลิ่นเหม็นหรือรังเกียจ แต่อาจเป็นช่วงเวลาที่แมวกำลังอ่านข่าวหรือวิเคราะห์ข้อมูลสำคัญจากกลิ่นเหล่านั้นอย่างละเอียด เป็นเหมือนการสื่อสารทางเคมีที่แมวใช้สื่อกับโลกของมันเอง การตั้งใจสังเกตพฤติกรรม Flehmen response นี้จะช่วยเพิ่มความเข้าใจในพฤติกรรมของแมว และทำให้เราดูแลและใกล้ชิดกับเพื่อนขนปุยน้อยได้ดีขึ้นอย่างแน่นอนครับ

If it smells fishy, looks grayish, or itches it’s not “normal.” You don’t need to panic, but don’t ignore it either. Your body whispers before it screams 🫣listen early Now I know: soap can’t fix what probiotics and doctor visits can. Normalize talking about vaginal health like we talk about sk
