From 1 July 2020, the NSW Government is changing the law regarding cat desexing. Owners of cats not desexed by four months of age will be required to pay an $80 annual permit in addition to their one-off lifetime pet registration fee.
Although this is earlier than many people may be used to, we can assure you there will not be any long term adverse health effects from desexing before 4 months of age.
