Single Polygonum is a walking tree and Tian Polygonum thinks that ten thousand cats will pass through it without a piece of hair touching its body. Unexpectedly, it will fall on Bai Xun's body. The idea comes from the talk about sucking cats in space and the cat movies on Station B. Yes, it's the one where the cat owner craves catnip pillows and chews on wooden sticks (laughs). Key points: cloud raising cats, cloud sucking cats. The knowledge about cats in the article comes from the Internet and Tieba popular science posts. If you have any questions, please point out. Because sooner or later I will have a cat (laughs)
