Rabbits beware: There's a hungry 13-foot-long snake in the grass. Snake owner Thomas M. Thorton, 26, reported Sunday night that his pet boa constrictor had slithered away from his Syracuse, N.Y., home. He told police that the snake could become "easily agitated" because it had not been fed its usual daily meal of a full-grown rabbit. Thorton said the snake measures 1 foot around, 13 feet long and weighs about 85 pounds. He said he put the snake in the grass for a moment, and when he looked down his pet had escaped. Police said a helicopter was sent to light up the area, near the Burnet Park Zoo, but the snake was not found. Police said they do not believe the snake poses a danger to people.
