Maus often possess very musical voices. They are known to chirp, chortle, and emit other distinctly unusual vocalizations when stimulated. Another behavior, quite common in happy Maus, has been described as "wiggle-tail. " The cat, whether female or male, wiggles and twitches its tail, and appears to be marking territory, also known as spraying, but during this behavior the Mau is not releasing urine.
