A marmoset discovered on a London bus has raised concerns about a possible rise in the abandonment of primates following recent changes to pet ownership regulations. The small primate, found inside a laundry bag on a 302 bus on Friday morning, was rescued by the Royal Society for the Prevention of Cruelty to Animals (RSPCA) and subsequently named "Oyster," referencing the Transport for London payment card.

Since April, new Animal Welfare Regulations in England have mandated that individuals must obtain a licence to keep primates as pets. This regulatory update applies to all primate species and aims to ensure higher standards of care and animal welfare. Authorities estimate that approximately 5,000 primates are currently kept as companion animals in England.

Clare Dew, the RSPCA’s chief inspector for London, expressed concern that the marmoset discovered on the bus could be indicative of a wider issue. Dew stated it would not be surprising if this case marks the beginning of increased primate abandonment linked to difficulties complying with the new licensing requirements.

The incident underscores the challenges faced by both regulatory bodies and animal welfare organizations as they adjust to the new rules. While the licensing system seeks to promote responsible ownership and protect primates from neglect or exploitation, it may also inadvertently prompt some owners to abandon these animals to avoid the licensing process.

The RSPCA continues its efforts to locate the owner of the marmoset and provide care for the rescued animal. The organization has urged current and prospective primate owners to adhere to the updated legal requirements to prevent harm to the animals and avoid potential legal consequences.
