Catford used to be famous for two things: The giant cat and the dog racing track. Then the dog track closed down ...
The giant cat is either quirky and amusing, or grotesque and tasteless, depending on your point of view. I love it, no one else has one!
It has its own page, under public art on the Lewisham Council Website
It gets a mention in Catford's Wikipedia entry and there's another picture of it here
