“Trap-Neuter-Return” (TNR) is a commonly used science-based animal birth control methodology that is used globally to assist with the humane management of companion animal populations. With the establishment of Cat Colony Care Programme (CCCP) in the 2000s in Hong Kong, volunteers joined the programme hoping to help humanely manage the cat populations around Yung Shue Wan in North Lamma. At the time, the feral cat population was reported to be approximately 600.
To demonstrate the success of the programme, the SPCA conducts annual, line transect surveys to monitor the positive impact on cat population management on Lamma.
These surveys do not aim to count every single cat but reflect the general population trends. We are excited to share our success in the real world that TNR does work well as a tool for the humane management of animals.
Key data to demonstrate the success of CCCP on the selected site on Lamma Island:
Over 500 street cats from Lamma were desexed since the programme started
The number of street cats seen on the transect count decreased from 107 in 2002 to 0 recorded in 2024
Over time a higher percentage of street cats seen were neutered colony cats
To achieve success in the effective reduction and control of cats, it is more than just desexing street cats but also requires input from different perspectives. Knowing that, a holistic approach is key and the SPCA has implemented a raft of supportive programmes aiming to improve overall cat welfare and assist with cat management:
Reduction and control of cats – A multi-pronged approach
Education
Educating registered volunteer carers and helpers, cat owners, residents on the island about cat welfare
Responsible pet ownership
Promoting the importance of sterilisation to cat owners of working cats and companion cats
Pet traders and breeders
Advocating for regulations on cat trading and breeding
Street cats
Desexing street cats by setting up cat colony through CCCP and TNR
