The comment whisker specifies a textual comment on the CATS packet. The content is an arbitrary byte string. \textbf{A valid CATS packet may contain zero or more comment whiskers.} In this case, their content should be concatenated together. This allows for comments longer than 255 bytes. After concatenation, the result must be valid UTF-8. Note that an individual comment whisker may or may not be valid UTF-8.
