The cat Mick Jagger reportedly carried around in his pocket was named Lewis.
Lewis is remembered in Rolling Stones lore as an unusual companion associated with Jagger during the band’s early years. The detail survives mainly as a colorful anecdote rather than a major documented episode in the group’s history, which is why it is often phrased as “reportedly.”
The story fits the eccentric image surrounding the Rolling Stones in the 1960s, when the band’s public persona mixed rebellious music, flamboyant fashion and tales of unconventional behavior. It should not be confused with the band’s many references to animals in songs, album artwork and stage imagery.
A neighbouring fact fans often ask about is the Stones’ breakthrough period: the group formed in London in 1962, with Mick Jagger and Keith Richards at its core. Their early blues influence helped distinguish them from other British rock groups of the era.
