West Ham defender Kurt Zouma has apologised after a disturbing video surfaced online of him kicking and slapping a cat, with his club publicly condemning the footage and vowing to deal with the matter.

Zouma is seen in the disturbing clip dropping, kicking and slapping the animal, while laughter can be heard in the background.

The 27-year-old then chases the cat, before throwing a pair of shoes at it and slapping its head.

West Ham have condemned Zouma's actions to The Sun newspaper in a strongly-worded statement following the publication of the clip.

"West Ham United unreservedly condemns the actions of our player, Kurt Zouma, in the video that has circulated," West Ham said in a statement.

"We have spoken to Kurt and will be dealing with the matter internally, but we would like to make it clear that we in no way condone cruelty towards animals."

Zouma has also released a statement, apologising for his actions and expressing his regret.

He said: "I want to apologise for my actions. There are no excuses for my behaviour, which I sincerely regret.

"I also want to say how deeply sorry I am to anyone who was upset by the video. I would like to assure everyone that our two cats are perfectly fine and healthy.

"They are loved and cherished by our entire family, and this behaviour was an isolated incident that will not happen again."

Zouma's brother, Dagenham & Redbridge defender Yoan, has been condemned by his club for filming the video and for "his reactions to the events shown".

A Dagenham statement read: "Since first becoming aware of the incident this morning the club has had discussions with Yoan and we will now take some time to consider our response, which we will of course make public in due course.

"However, in the meantime we would like to make it completely clear that we in no way condone any form of cruelty towards animals and take this matter very seriously."

Yoan Zouma said he "deeply regretted" his actions in his own statement on the club’s official website.

"I deeply regret my involvement in the video that has been widely circulated and unreservedly apologise, not only for my actions, but for the upset and distress this will have caused to so many people," he said.

"I am now taking time to reflect on what I have done but wish to assure everyone that this was an isolated incident and not something that I am proud of."

A spokesperson for animal welfare charity the RSPCA said: "This is a very upsetting video. It's never acceptable to kick, hit or slap an animal, for punishment or otherwise.

"We are so grateful to people who report suspected animal suffering to us and we would like to reassure people we will always look into and, if necessary, investigate any complaints made to us about animal welfare."
