Waves Stride

Q：Two cats who were strangers encountered each other unexpectedly on the road one day. After conversing, they learned that they both needed to cross a very dangerous bridge. The white cat and the black cat decided to watch out for each other and cross the bridge together. The white cat bravely volunteered to go ahead and test whether the bridge was stable, while the black cat followed behind, keeping an eye out for any dangers nearby.
As the two cats walked slowly, suddenly a strong wind blew and knocked the white cat off balance. Seeing this, the black cat hurriedly rushed forward to rescue it. At the critical moment, the black cat saved the white cat. Still shaken, the white cat uttered just one sentence to the black cat. What did it say?
A：Meow~~
