The Jesselton International School Charity Association (JISCA) and Drama Club recently organised a donation drive for Animal Lover Independent Rescuer (ALIR), an NGO dedicated to rescuing and caring for abandoned animals.
Together, our community made a difference. Animal food supplies were collected through the generosity of JIS parents, while the Jesselton International School Charity Association (JISCA) contributed RM5,000 in support of the Drama Club’s fundraising efforts.
We are incredibly proud of our students for showing such kindness and responsibility toward animal welfare.
If you would like to support ALIR, you can reach them via WhatsApp: +60 17-899 5159.
