Target: Emma P. Reynolds, U.K. Minister for Environment, Food and Rural Affairs
Goal: Hold accountable those responsible for the abandonment of the marmoset and ensure stricter enforcement of primate welfare laws.
The recent discovery of a “stressed and dehydrated” common marmoset abandoned in a laundry bag on a London bus should serve as a wake-up call regarding the treatment of primates as pets. The female marmoset, named Oyster, was found confined in a cage inside the bag, indicating a blatant disregard for her welfare. Her situation is not isolated; it reflects a pattern of neglect and abuse that animal welfare organizations warn may escalate following the introduction of new primate licensing laws.
The RSPCA has documented 238 cases of primate neglect and cruelty between 2021 and 2025, highlighting the urgent need for accountability in cases like Oyster’s. According to RSPCA investigators, her abandonment was deliberate, potentially a reaction to the recent legislation requiring all primate owners to obtain licenses. While this law, introduced to mitigate the suffering of primates kept as pets, has begun to see some compliance, continued vigilance is necessary. The concern remains that many may choose the cruel option of abandonment rather than face the legal responsibilities imposed by the new regulations.
Enforcing this law is crucial to preventing future instances of neglect and abandonment of primates. Effective measures must be taken to ensure all violators are held accountable, thus preserving the welfare of these intelligent and sensitive animals. Therefore, it is imperative to demand that those responsible for abandoning Oyster face appropriate punishment, and that local authorities intensify efforts to enforce existing regulations strictly.
PETITION LETTER:
Dear Minister Reynolds,
The distressing case of a common marmoset, discovered abandoned inside a laundry bag on a London bus, highlights the pressing issue of primate welfare under the new licensing laws. Her abandonment, referred to as “clearly intentional,” raises alarming questions about the treatment of these intelligent creatures following changes in legislation aimed at protecting them. Oyster was found in a cage, dehydrated, and stressed, which clearly illustrates the dire consequences of neglect and abandonment.
With the RSPCA noting a significant number of reports involving primate neglect, including 238 cases from 2021 to 2025, there is a pressing need for accountability for such actions. As stated by experts, the increased risk of abandonment linked to the new licensing requirements presents grave concerns for the future welfare of primates in private ownership. It is crucial that the individuals responsible for such inhumane actions face consequences, creating a deterrent against further abuse or neglect.
We urge you to take immediate action to ensure that those accountable for abandoning primates are punished appropriately, and that strict enforcement of the current welfare regulations is implemented. It is essential for the welfare of all primates in England that swift and decisive action is taken to prevent further occurrences of this kind.
Sincerely,
[Your Name Here]
