A video clip showing a boy throwing a cat off an HDB block in Boon Lay has sparked public concern.

CCTV footage of the incident, which happened on Wednesday (Dec 14) afternoon, has been circulating on social media.

In the clip, the child was seen exiting the lift on the 22nd floor of a block along Boon Lay Avenue together with a cat. 

He picked up the animal and looked around before throwing the cat off the building.

A loud bang was heard moments later.

On Thursday, Singapore Society for the Prevention of Cruelty to Animals (SPCA) said in a Facebook post that it was alerted to the incident. It has since escalated the case to the authorities. 

"We are deeply disturbed by the actions captured in the footage," SPCA wrote. 

"Animal abuse and cruelty have no place in our society. We stand strongly against animal cruelty and are working closely with the authorities on the case for the next course of action." 

SPCA also urged the public to contact their emergency hotline 6287 5355 ext 9 or make a report on their website if they witness any cases of suspected animal abuse. 

After learning of the incident, some people started an online petition calling for justice for the community cat. It has received close to 5,000 signatures.
