What is what does it mean when cat wags tail?

Cats wagging their tails is a complex behavior and, unlike dogs, it doesn't automatically signify happiness. The meaning depends on the context and the rest of the cat's body language. Here's a breakdown:

  • Agitation or Irritation: This is the most common reason for tail wagging in cats. A quick, jerky wag often indicates the cat is feeling annoyed, frustrated, or overstimulated. Pay attention to other signs like flattened ears, dilated pupils, or tense muscles. A low, sweeping tail wag can also signal a cat is considering aggression.

  • Excitement or Focus: Sometimes, a cat will wag its tail when it's intensely focused on something, like prey. This type of wag is often accompanied by other predatory behaviors like stalking or crouching.

  • Attention Seeking: A subtle, slow tail sway might be the cat's way of trying to get your attention, especially if paired with vocalizations like meowing.

  • Greeting (Sometimes): Occasionally, a cat will give a gentle, upright tail wag as a greeting, especially if it knows you well. This is usually accompanied by a relaxed posture and purring. It is closest to a dog's wag.

Key Takeaway: Always consider the entire cat's body language and the situation to understand what the tail wag means. Don't assume it's always a sign of happiness like it is in dogs.
