Welcome...
C4 is the jointly funded spay and neuter programme for cats in the London region.
​
Our scheme enables cat owners who live inside the M25 ring and receive qualifying benefits or low incomes the opportunity to have their cats neutered and microchipped for £10 via our network of partner vets in London.
​​​
We're funded by the generosity of donors to four animal welfare charities (please see below).

...over 200, 000 cats have been neutered through C4 since we started in 1999*
C4 is a coalition of charities. Links on the site will take you to our member charities' external sites, or to other trusted animal welfare websites.
Sites will always open in a new window.
