"With the special rates granted to our organisation by participating veterinary clinics (whose kind assistance we are very grateful for), we are able to sponsor the cost of approximately 140 operations every month. We thank our donors whose funding has made this possible. "
"In July last year, a local newspaper reported that culling costs for 2003 rose 20 per cent. That year, AVA cancelled its five-year-old Stray Cat Rehabilitation Scheme (SCRS), following the Sars scare.
Eighty per cent of readers surveyed objected to AVA’s annual $600,000 culling bill, and more than half felt funds should go to animal welfare groups to re-home or sterilise strays."
-Why animal welfare groups in Singapore can’t reach out to the authorities
"AVA had previously worked with animal welfare groups and town councils on a Stray Cat Rehabilitation Scheme to control the stray cat population through sterilisation and responsible management of the sterilised stray cats by volunteer caregivers.
The scheme was terminated in 2003 as there was no reduction in the number of strays or stray cat complaints.
In 2007, AVA and town councils agreed on a Stray Cat Sterilisation Programme. AVA would subsidise the cost of the sterilisation of stray cats if the caregivers of stray cats, town councils and the community in the respective precincts agreed to participate in the programme.
To date, we have not been approached by any town councils or caregivers."
-Scheme in place but no takers

so it seems that the sterilisation programme in Singapore is as such:
Since 1991, SPCA has been giving out free sterilisation vouchers for sterilisation of stray cats.
In 1998, AVA started the Stray Cat Rehabilitation Scheme, based on a study which showed its success. Under this scheme, both SPCA and CWS worked together with the AVA and town councils to sterilise stray cats.
In 2003, this scheme was terminated citing 'no reduction in the number of strays or stray cat complains', which contradicted its earlier study.
In 2007, AVA and town councils 'agreed on a Stray Cat Sterilisation Programme' where AVA would sponsor cost of sterilising stray cats in participating precincts. However, they have not yet been approached.
At the moment, it seems to me that animal welfare groups are working among themselves to tackle the stray problem.
