I texted the vet and he said Putih's surgery has not been done yet as he had to source for the materials. I have advised Beng Kai of his options for Putih, ie. if it is urgent, he could transfer Putih to another vet if Putih is fit enough to be moved. As Putih's rescuer, it is totally Beng Kai's decision. We are only helping with advice and funds.
Updates at 4.15pm: The vet has sourced for the materials and the surgery will be done soon.
