France defender Zouma faced a public outcry and was subsequently charged by the RSPCA after footage emerged last month of him kicking and slapping the cat.
Zouma and the club also lost sponsorship deals following the appalling incident, while the player has been jeered by opposition fans ever since.
But the Hammers have now confirmed that “significant payments” have been made to nine animal charities at home and abroad.
“A total of nine organisations, supporting the care and wellbeing of animals both in the United Kingdom and internationally, have been identified to receive significant payments which will go towards supporting the fantastic work they do.”
The charities include Cats Protection, the People’s Dispensary for Sick Animals and International Fund Animal Welfare, which is currently providing support to animal shelters operating in war-torn Ukraine.
The club added: “West Ham United would like to thank everyone who contacted the club to propose animal welfare charities and good causes, along with our supporters who have been involved in the process of identifying those who have received financial support, ensuring that a huge positive has come from something negative.”
