CATS is a mixed 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 three levels so players of most skill levels can find a fit. Social events include tennis round-robins and outings to professional sports events.



Sad news, several losses: In the past few weeks, several former CATS members –Bill Horstman, Janis Peltier, Bob Cooley, Richard Eastline — have passed on. We offer our condolences to their families, and remember our old friends fondly. To see their obituaries, click here.

New ID cards from Lakeshore:
Lakeshore has created new, laminated ID cards for all CATS members. You may pick up your new card at the front desk the next time you are there. Please show the card to the receptionist when you enter the club so the bar code can be scanned.

CATS’ Covid Policies: CATS will follow the guidelines recommended or mandated by the City of Chicago and the State of Illinois.

Members-only section: This area of the website includes the member directory, division schedules, team lists and sub lists for each division, the prize list and more.

Fun With CATS is a collaboration between the Social Committee and the Director of Communications. It was published occasionally until CATS was able to resume playing tennis as a way of keeping in touch with each other and remembering how much fun we have on and off the court. Issues looked at photos of past events, shared news about members or information about tennis instruction—anything we can think of that’s fun and relevant to CATS! Issues generally have a main article followed by news tidbits. Issues to date are below.
