Zheng Tan lay on the living room sofa, his tail tip gently wagging.
Zheng Tan liked to think in this state, and as for the tail wagging, it was a habit he had developed after becoming a cat, originating from an unconscious movement. Just as some people liked to tap their fingers on the desk while thinking, Zheng Tan enjoyed swaying his tail tip while pondering on the sofa.
In fact, many cats liked this, but not every cat pondered the complex issues like Zheng Tan did. This action might just be their way of expressing a sense of comfort, indicating they were in a good mood and living comfortably. Or perhaps, like Zheng Tan, they were mulling over some matters, though not as complex as his, but still unpredictable to people. After all, the minds of cats are hard to guess.
