To bolster a lineup that features Pretty Little Liars and Melissa & Joey, ABC Family greenlighted three pilots Tuesday.

"Adding depth to the network's original programming slate is one of our biggest priorities going into next year," said Michael Riley, president of ABC Family.

Nine Lives is based on the Celia Thomson novel The Nine Lives of Chloe King. The series, produced by Dan Berendsen (Sabrina the Teenage Witch), follows a girl who discovers she has catlike abilities.

Switched at Birth, produced by Lizzy Weiss (Blue Crush), centers on two teenage girls who discover they were accidentally switched at birth. One comes from a well-off family, while the other lost her hearing as a child and grew up in a poor neighborhood.

Strut focuses on a showgirl named Roxy, who marries a stranger after a crazy night and ends up in Texas coaching a struggling drill team. The series will be executive-produced by Karey Burke (Miss Guided).

"These pilots offer a great mix of heartfelt and compelling storytelling that our audience has come to expect from us," said Kate Juergens, ABC Family's executive vice president of original programming and development.

The three one-hour dramas are scheduled to go into production this fall.
