Narrative:

We were cleared for takeoff on runway 36 right as we initiated the takeoff roll (power about 45%) rolling about 20 kts; tower cancelled our takeoff clearance due to a visual sighting of a coyote on the runway. We pulled power to idle and stopped. The tower could not declare the runway clear for some time. Since we had only rolled 500 ft we recomputed the data; changing the V speeds; and setting the flaps at 14.5 as the new takeoff data stated. When the coyote was observed clear of the runway; we were again cleared for takeoff. As the throttles were advanced got an aural flap warning; so we again rejected the takeoff and cleared the runway. Speed was estimated at 40 kts so minimal braking was used. After recomputing the takeoff data and reconfiguring the aircraft; we neglected to input the new flap setting into the mcd. Practice double aborts in the sim.
