I was on flt. 3 (jfk-lax) on 7/31/14, seated in 10F. The pax in 10A and 10B, each had cats in containers. One cat was quiet, the other meowed continuously. The Bose noise cancelling headphones helped a lot to muffle the noise; the engine noise (very prominent in 10F) was also a "relief" from the meowing. [Crying babies eventually stop crying]
As I noted the headphones helped a lot. What is the (AA) rule re cats meowing (if there is one). If they were in coach--NO supplied headphones and probably much less engine noise, the meowing would affect even more pax.
See if there is a Hungry dog on board
