Abandoned Monkey Found in Laundry Bag on London Bus: New Law 2026

An abandoned monkey found in a laundry bag on a London bus has sparked concerns that new primate licensing laws are driving owners to dump their pets. The female common marmoset, now named Oyster after the London transport payment system, was discovered on a 302 bus in Kensal Rise on Friday by a passenger whose buggy was blocked by the bag containing the monkey in a cage. The bus driver contacted the RSPCA, which reported handling 238 cases of primate neglect and cruelty between 2021 and 2025.

New Primate License Law Sparks Abandonment Fears

In April, England implemented strict new legislation requiring all primate owners to obtain a license and microchip their animals. Owners who failed to apply by 6 April face unlimited fines or imprisonment. The RSPCA’s chief investigator, Clare Dew, noted that the abandoned monkey had not been microchipped and that the dumping “was clearly intentional,” likely a direct result of the new law.

Alison Cronin, director of Monkey World and a contributor to the legislation, stated that well-meaning people have been misled by social media promotions of wild animals as domestic pets. She emphasized that UK breeders have profited from this misconception, but the law change now requires them to ensure monkeys are only sold into suitable environments.

Background on Primate Ownership and Welfare

A Born Free survey in January indicated limited uptake of the new licensing system, but Cronin observed that many owners have since complied. She clarified that monkey abandonments are “nothing new” and predate the law, noting that these animals have been subject to abuse and neglect for years. The RSPCA’s data underscores a persistent problem: over 238 reports in four years, with many cases involving similar concealment.

The bus driver and Metroline staff are cooperating with RSPCA inquiries to trace the person responsible for dumping Oyster. The common marmoset was found stressed and dehydrated, well concealed in the laundry bag. Animal welfare charities warn this could be the first of many such cases as the law’s enforcement ramps up.

Key Takeaways for Pet Owners

• Primate ownership now requires a license and microchip in England.
• Failure to comply can result in unlimited fines or jail time.
• If you can no longer care for your primate, contact a rescue organization instead of abandoning it.
• The RSPCA advises that primates are wild animals, not suitable as domestic pets.
