Zouma was charged by the RSPCA after social media footage emerged last month showing the centre-back kicking and slapping the cat. A shoe was also thrown at the animal, while laughter was heard in the background.
The 27-year-old's two cats were confiscated by the RSPCA and West Ham fined him the maximum two weeks' wages, believed to be around £250,000. Zouma lost a sponsorship deal with his personal kit supplier Adidas following the incident.
The Premier League club on Friday revealed that "significant payments" have been made to nine animal charities at home and abroad. "West Ham United is pleased to confirm that financial donations have been made to a number of animal welfare charities following the club fine handed to Kurt Zouma," a statement said".
