A common marmoset, now named Oyster, was discovered abandoned in a cage on a London 302 bus last Friday, prompting an immediate rescue and a wider investigation.
A small monkey, found on Friday, July 19, 2024, lay hidden inside a cage, obscured by a laundry bag, on a public transport route.
A mother attempting to navigate the bus aisle with her pushchair encountered the protruding laundry bag in the luggage bay, leading directly to the discovery.
Following its rescue, the monkey, named Oyster, received a clean bill of health and has since settled into a dedicated sanctuary, away from the urban environment.
The RSPCA launched a full investigation into the abandonment, appealing for any witnesses to come forward with information.
Chief Inspector Clare Dew confirmed the monkey was left with some apple; it showed signs of dehydration upon discovery.
This incident signals a troubling trend directly linked to a significant change in law introduced in April.
New legislation now mandates that all primates kept in England must be licensed, a move wildlife campaigners anticipated would lead to such abandonments.
Owners unable or unwilling to meet these stringent new licensing requirements may resort to illegally dumping their primates, creating a crisis for animal welfare.
Animal welfare groups voice significant concern regarding the fate of numerous primates previously kept as pets, given the alarmingly low uptake of the new license system.
The incident is a direct consequence of the new legislation, a scenario animal welfare groups had predicted. It would be surprising if this marked the last instance of a primate being dumped across the country.

Historically, the RSPCA documented a disturbing pattern; between 2021 and 2025, rescuers responded to 238 reports of primate neglect and cruelty.
This recent abandonment on a public bus highlights the ongoing challenges in primate welfare and the enforcement of new regulations.
The new licensing system aims to elevate conditions for primates, yet its immediate effect appears to be an increase in desperate abandonments.
Meanwhile, the broader landscape of exotic pet ownership faces intense scrutiny, with campaigners pushing for stricter controls and greater public awareness.
The financial burden of meeting new welfare standards, coupled with the complexity of obtaining licenses, creates a powerful incentive for some owners to discard their animals.
This situation echoes past regulatory shifts in animal welfare, where initial enforcement often sees a spike in abandonments before compliance becomes widespread.
The long-term implications for primate populations in England remain uncertain, as sanctuaries face increasing pressure to accommodate rescued animals.
Public awareness campaigns are now critical to inform owners of their responsibilities and to prevent further instances of abandonment on London's streets and beyond.
