[2] An early mention of the team is in a newspaper article advertising trials at what is the modern day St. Dunstan's School playing fields on Canadian Avenue, Catford.

Finding their new surroundings to their liking, they gained promotion to Division 1 as champions in their inaugural season, finishing 11 points clear of second place Woolwich Polytechnic.

Whilst the league underwent various restructuring changes in the following years, The Kittens were promoted to the Premier Division (Section A) ahead of the 1910/11 season.

[2] Catford Southend played at a football ground in the southwestern corner of what is today Mountsfield Park from about 1909 until the start of World War I in 1914,[3] and then after the war[4] (the 1914 Ordnance Survey map shows the ground situated parallel to Laleham Road with its southern end just north of housing on Brownhill Road).

[3] Catford Southend continued to play at The Mount briefly but the ground was closed in January 1927,[3] and was absorbed into the wider Mountsfield Park.
