你可能已经注意到了一种神奇的植物，它能让猫咪无法抗拒，难以割舍。常常嗅到时会感到目眩神迷。这便是猫薄荷，它的叶片上含有一种名为内酯酸（nepetalactone）的化学物质。这种化学物质能够刺激猫的嗅觉和神经系统，从而引起猫的兴奋和愉悦感。由于猫的嗅觉系统异常敏锐，对于一些挥发性化学物质尤其敏感，猫薄荷中的内酯酸正是这种挥发性化学物质，可以刺激猫的嗅觉系统，从而引起兴奋和愉悦感。因此，cats tend to interact with catnip by rubbing their faces and bodies on it, rolling around in it, or even licking and chewing it. This is why cats love catnip.

Besides its stimulating effects on a cat's senses, catnip also has benefits for a cat's physical health. It can stimulate a cat's motor nervous system, promoting movement and digestion and helping to prevent constipation and obesity. Additionally, catnip has calming effects that can help reduce anxiety and stress in cats.

In summary, the reason cats enjoy catnip is because of its ability to stimulate their senses and promote overall well-being. If you have a feline friend at home, consider providing them with some toys filled with dried or freshcatnip for them to play with – it will make them happier and healthier!
