Between 2015 and 2016, the case of Macau-born National Taiwan University overseas student Chen Haoyang killing cats in Taipei drew sustained attention in Chinese-language public discussion. Public summaries and Taiwan Taipei District Court criminal judgment references, 105 Yi Zi No. 518 and No. 789, record that the stray cat Da Juzi was killed near a parking lot on Wenzhou Street in Da'an District in December 2015. While that case was pending, the same person killed Banban, a shop cat at a vegetarian restaurant in Wenshan District, in August 2016. On October 13, 2016, the Taipei District Court combined the two cases, found violations of Taiwan's Animal Protection Act, and sentenced Chen to a 10-month prison term plus a NT$350,000 fine.

Two cats remembered by name

Da Juzi was a stray cat around the Wenzhou Street parking area, while Banban was a shop cat at a Wenshan vegetarian restaurant. Their names remain in public memory because their deaths were not accidents but a serial animal-killing case that entered the courts.

Reoffending and public outrage

Public records say prosecutors had already sought summary punishment under the Animal Protection Act in the Da Juzi case when Banban was killed during the court process. The case became a major Chinese-language discussion point about animal protection law, university discipline and reoffending risk.

Court outcome

On October 13, 2016, the Taipei District Court combined the two cases. The court found that the conduct showed disregard for animal life and involved cruel methods. It sentenced Chen to a 10-month prison term and a NT$350,000 fine.
