A pet shop owner pleaded not guilty to torching her Las Vegas store, where firefighters rescued 27 puppies.

Shop owner Gloria Eun Hye Lee entered her plea Monday in state court to 31 felony and misdemeanor charges.

In another courtroom, a judge scheduled a March 10 preliminary hearing for co-defendant Kirk Bills on the same arson, conspiracy, burglary and attempted animal cruelty charges.

Authorities say Lee and Bills are seen on security video setting the Jan. 27 fire at Lee's Prince and Princess pet store.

Bills was arrested Feb. 7 in Crown Point, Ind., and returned to Las Vegas.

Lee is being held on $310,000 bail.

The two cases are expected to be consolidated before Lee's trial, scheduled in July.
