A technicality forced a judge to reject a plea agreement offered to a 17-year-old girl charged with burning a cat in an oven, New York prosecutors said.

Cheyenne Cherry had pleaded guilty and accepted a deal for one year in prison for animal cruelty in the May 6 fatal burning of her former roommate's cat, Tiger Lily, The New York Post reported Tuesday.

Bronx County Supreme Court Judge Margaret Clancy Monday withdrew the agreement after determining it was illegal to reduce a violent felony charge to a non-violent charge, The Post reported.

Prosecutors offered a new agreement in which Cherry could plead guilty to animal cruelty in exchange for two years in prison.

Cherry's lawyer, Danielle Follette, accused prosecutors of succumbing to pressure from animal rights activists who were following the proceedings.

Cherry next is to appear in court Dec. 2.
