The 'C4' scheme, established in 2002, is a joint initiative by major animal charities working in Greater London to tackle the problem of too many cats.
There are thousands of unwanted, neglected and stray cats in London, yet their plight could have been easily been prevented by neutering.
The C4 scheme offers FREE neutering for cats within the M25 area whose owners receive certain state benefits, are on a low income or are students. The scheme also includes neutering of stray cats being temporarily fed.
