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.

New Entry System at Lakeshore: Lake Shore Fitness has a new entry system which will require you to sign an electronic waiver form to enter the building. You will be required to enter your name, address, email, and phone number, and sign your name on their iPad. You will be given scan code which will be adhered to your present CATS entry card. You will use it to scan it when you enter. This will take 2-3 minutes per person. Most players on Wednesday night arrive shortly before 9 which will cause a delaying backup. As an alternative please use this link to complete the tasks. Then when you arrive, starting next Wednesday, state you name and your name will be on a list and you will receive your scan code.

Rules Change: Effective April 25, there will be no switching players at 10:45. The new rule for all divisions reads: “Follow normal rotation unless there is a tie-breaker, then each captain may chose which players to play in the tie-breaker. Service rotation is not altered.” If you have questions about this, please talk to your team captain or division coordinator.
