A raccoon photographed riding the Tube has been identified as a "mischievous" 15-week-old called Olivia.

Her animal trainer-owner Kimberly Unger contacted the BBC after spotting Olivia in a news story about unusual pets

A second raccoon, assumed to be Olivia, spotted being walked on a lead near Oxford Street, was in fact a young male racoon she owns called Winston.

But the undoubted star of her four-strong raccoon troupe is Melanie, who appeared in a TV talent show in 2013.

Melanie, her eldest, featured in Britain's Got Talent, aged one. She performed a series of actions to music, but failed to charm Simon Cowell, who buzzed her out of the TV show.

"Melanie did ever so well. She was rolling over, playing dead, climbing a ladder, but Simon didn't like the fact she wasn't dancing. Dancing wasn't part of her routine though, so that's not her fault," Miss Unger said.

Miss Unger, 35, has revealed Winston - who was photographed on a lead near Oxford Street on Friday - is a fidgety male who is a week younger than Olivia.

She said she had brought Winston to the capital from his home in Kent to help socialise him.

"They are highly intelligent and need a lot of mental and physical stimulation. They get easily bored, that's why it's good to take them out regularly," she said.

"London is a great place to take them to get them used to noise, traffic, people and different smells. If you do this from when they are young it doesn't stress them out."

She accepted some people would see her as eccentric but said she hoped to study captive raccoons to measure their intelligence, to help better protect the species.

She agreed with the RSPCA that raccoons were not suitable pets for most people because they demand a lot of attention.

A spokesman for the charity said: "We would strongly discourage anyone from buying or keeping them. Sadly, the needs of raccoons cannot adequately be met within typical household environments."

In the wild in their native North America raccoons have an average lifespan of between one to three years.
