CATS is a coed doubles league that offers fun both on and off the courts with year-round tennis and social events.

CATS members play indoors at Lakeshore Sport & Fitness on Wednesday nights from 9-11 PM in Fall, Winter/Spring and Summer Sessions. Teams are divided into C, B, A and Open Levels so players of most skill levels can find a fit. Social events include tennis round-robins and outings to professional sports events.
