Cat Deaths: A series of cat deaths and injuries occurred earlier this year in various parts of Singapore.

Suspected Dog Attacks: These incidents were believed to be the result of attacks by a pack of dogs.

Geographical Spread: The affected areas included Ang Mo Kio, Seletar, Hougang, Paya Lebar, and possibly more.

Cat Feeder Response: Cat feeders in the community started patrolling at night to protect the cats from potential dog attacks.

Alerting Authorities: NParks and animal welfare organizations were alerted to the incidents, and the Society for the Prevention of Cruelty to Animals (SPCA) called on the public to help identify the dogs.

AVS Involvement: The Animal and Veterinary Service (AVS), part of the National Parks Board, responded to a sighting of three free-roaming dogs at Fernvale Lane on Sep. 8.

Dog Capture: Two of the three dogs believed to be responsible for the attacks were captured by AVS after they exhibited aggressive behavior toward residents.

Care and Monitoring: AVS is currently caring for the captured dogs and plans to work with animal welfare groups to rehome them. They will also continue to monitor the situation.

Territorial Behavior: The article explains that dogs are territorial animals with an instinct to chase and catch things, and they may bark at humans or other animals.

Sterilization: The dogs involved had previously been sterilized as part of a nationwide Trap-Neuter-Release-Manage (TNRM) program. AVS had deployed traps to capture them but faced challenges in doing so due to the dogs' roaming behavior.
