Lewis is the name of a cat from Fairfield, Connecticut, who garnered mass media attention for being placed under house arrest in March 2006.

Ruth Cisero, Lewis's owner, was arrested and charged with failure to comply with a restraint order which the prosecuting attorney later changed to reckless endangerment.

She further stated that she believed that Lewis may have been acting in self-defence, saying that "One day he came home covered in eggs because someone had egged him and another time a woman sprayed him with a hose.

Ruth Cisero, Lewis's owner, was granted accelerated rehabilitation, which would result in her record being expunged if she successfully completed two years of probation.

In July 2008, the judge dismissed the reckless endangerment charge against Cisero, concluding she had met terms of a special probation for first-time offenders.
