A md-80 captain checked the takeoff configuration warning with no response during taxi out but at about 110 KTS the slat disagree and takeoff configuration warning alerted so the captain rejected the takeoff then returned to the gate for maintenance and brake cooling.

Narrative:
Rejected takeoff due to takeoff configuration warning and slat disagree. Rejection speed was at 110kts. We had a normal preflight with a normal takeoff warning check. On taxi out I momentarily pushed the power levers to full travel and back to confirm proper takeoff configuration. We had a normal takeoff roll until just prior to 110 kts. At that point we experienced an aural takeoff warning followed by a slat disagree. I had to question how or if the aircraft would fly with an unknown slat position. I rejected the takeoff. On taxi in the slat disagree light cycled on and off several times. In conclusion; I now feel that there is a better chance of a false warning than a slat failure that would change its position. I now feel the better choice would have been to continue the take off.
