Stray cats and dogs have been an age-old problem for cities around the world.
Millions wander the streets and alleys of the Los Angeles area alone.
Southern California Public Radio's Jed Kim reports on a group working to reduce those numbers drastically using a staple of reality TV -- a cash prize.
The Found Animals Foundation is administering a $25 million prize that would be given to any person or group that can develop a single drug treatment that would permanently and safely sterilize both male and female cats and dogs.
