Happy Ratter is a new urban vermin hunting sport. No rats are harmed; they are safe inside PVC tubes. On Dec. 9, PCOTC will offer a two-hour overview of Happy Ratters trials beginning at 8:30 am, followed by two trials from 11:00 to 4:00 pm. Happy Ratters provides a fun, trusting environment, a titling program, and a program that encourages camaraderie and support between competitions. The seminar is free and all are welcome.
