That is what we discovered on Wikipedia concerning the Geelong Cats:

The Geelong Football Club, nicknamed the Cats, is a professional Australian rules football club based in Geelong, Victoria, Australia. The club competes in the Australian Football League (AFL), the sport's premier competition. The club formed on 13 April 1859, making it the second-oldest AFL side after Melbourne and one of the oldest football clubs in the world.

In the 1860s, Geelong participated in a series of Challenge Cup competitions, and was a foundation member of both the Victorian Football Association (VFA) in 1877 and the Victorian Football League (VFL) in 1897, now the national AFL. The club won the Western District Challenge Cup in 1875, a then-record seven VFA premierships between 1878 and 1886, and six VFL premierships by 1963, after which it experienced a 44-year waiting period until it won its next premiership, a grand final record 119-point victory in 2007. Geelong won a further three premierships in 2009, 2011 and 2022. The Cats have fierce competitive rivalries with Hawthorn and Collingwood.

Geelong play most of their home games at Kardinia Park in South Geelong (nicknamed the Cattery and known for sponsorship reasons as GMHBA Stadium) and play the remainder at the Melbourne Cricket Ground. Geelong's traditional guernsey colours are white with navy blue hoops. The club's nickname was first used in 1923 after a run of losses prompted a local cartoonist to suggest that the club needed a black cat to bring it good luck. The club's official team song and anthem is "We Are Geelong".

Geelong also fields a reserves men's team in the Victorian Football League (VFL), a senior women's team in the AFL Women's (AFLW) and a reserves women's team in the VFL Women's (VFLW) competitions.
