Feline tail quivering. What’s its meaning? Infographic.

The interesting aspect of domestic cat tail quivering is that it occurs during what appears to be two entirely different circumstances. In the infographic I explore a possible connection between these circumstances in the emotional state of the cat and the message that she/he wishes to impart to others. Nature’s evolution dictates that there is a connection and I believe it is the similar emotions experienced by the cat at these distinctly different occasions.

The erect position of the tail in a friendly greeting originates in the kitten approaching their mother when she may instinctively lick her kittens’ bottoms to stimulate defecation and to keep them clean.

Here is some expanded information about this aspect of domestic cat behaviour gleaned in a conversation with an AI bot (Chat GPT):

Question: What do the experts say is behind domestic cat tail quivering when they are pleased to see someone and also employed when spraying urine?

Response: Experts in feline behavior interpret tail quivering in domestic cats as a form of communication and emotional expression. The behavior can have different meanings depending on the context:

  1. Excitement and Affection:
    • When a cat quivers its tail upon seeing someone it likes, it often signals excitement or happiness. The quivering tail is held upright and may vibrate slightly at the tip. This behavior is commonly observed when a cat greets a familiar person, showing trust and affection.
  2. Marking Territory (Spraying):
    • Tail quivering is also seen during spraying, a behavior used to mark territory. When cats spray, they back up to a vertical surface, lift their tail high, and release a small amount of urine. The quivering tail in this scenario often accompanies the act of marking and is associated with territorial or reproductive instincts.

The overlap in the tail-quivering behavior in these two contexts lies in the way cats use their tails as a communicative tool. In both cases, the upright position and quivering are strong signals. The distinction is largely about the accompanying behaviors and circumstances:

  • Greeting: No urine, friendly body language.
  • Spraying: Marking surfaces with urine, often more purposeful or territorial posture.

Understanding the context and other signals in the cat’s behavior helps clarify the intent behind the tail quivering.

Question: Might there by a connection between the two circumstances? In greeting the cat is saying ‘this is me!’ In spraying urine, the cat is also saying the same thing.

Response: Yes, there is a compelling connection between the two circumstances, and your observation is insightful. Both behaviors—tail quivering during greetings and spraying urine—serve as ways for cats to assert their identity and communicate “this is me!”

Common Themes Between the Behaviors

  1. Identity Assertion:
    • In both cases, the cat is using its body and actions to express individuality. During a greeting, the cat’s tail quiver is a way of showing excitement and a positive association with someone. It’s a non-verbal “hello, it’s me!”
    • Similarly, when a cat sprays urine, the scent it leaves behind is a chemical signature, saying “this is my territory, and this is who I am.”
  2. Emotional Intensity:
    • Tail quivering is associated with high emotional states, whether it’s joy and anticipation during a greeting or the determination to claim territory while spraying. The upright tail and quivering movement emphasize the importance of the moment to the cat.
  3. Communicative Intent:
    • Both actions are forms of communication, not only to humans or other animals but as a way to reinforce the cat’s presence in its environment. In greetings, the communication is friendly and directed at a social partner. In spraying, the message is more territorial or reproductive but still an assertion of identity.

Biological and Evolutionary Perspective

From an evolutionary standpoint, both behaviors likely evolved as adaptations for clear, efficient communication:

  • Friendly tail quivering fosters social bonds, which are beneficial in the cat’s relationships with humans or other cats.
  • Spraying marks territory or conveys reproductive status, which is crucial for survival and mating success.

Conclusion

The similarity in the tail quivering’s role in both scenarios supports the idea that this behavior is fundamentally about self-expression and identity. The context determines whether the message is one of affection or territoriality. Cats are masters of multi-functional communication, and this shared element of “this is me!” illustrates how their behaviors can serve overlapping purposes depending on the situation.
