A Dutch entrepreneur who cycled from Amsterdam to London drew curious stares every mile along the way thanks to his four-legged travel companions.

While it’s not unusual to hear tales about people travelling with their pet dogs, Thomas Vles went the unusual route and made the 300-mile journey with his two cats, Mushi and Cheesy.

The 10-month-old animals rode in a custom-built glass enclosure inside the box of Thomas’ cargo bike, allowing them to enjoy the scenery while delighting passers-by.

Thomas and the cats visited a number of tourist sites in London, including Palace of Westminster

Their journey included an overnight ride on a ferry from Hook of Holland to Harwich

It took almost three days to complete the journey by bicycle, ferry and truck, and Thomas said the cats didn’t seem to mind their time on the Kittymobile, even in the rain.

The 30-year-old founder and CEO of a company called Poopy Cat told MailOnline Travel: ‘Mushi and Cheesy are used to travelling all their lives. They always travel with me on the bike and the scooter in Amsterdam.

‘They’re pretty used to new environments and new situations. They liked spending time in the Kittymobile.

‘It was the least stressful environment for them. Inside the cage they had a cat toilet and a modern playhouse.’

He said they drew a lot of interest as they passed people, especially once they arrived in the UK after taking a ferry from Hook of Holland to Harwich.

‘They would say “What is that thing?” when they saw the bike. Most people were really enthusiastic and when they got closer and saw the cats they would say “Oh, wow”.’

Thomas made the trek with Mushi and Cheesy, who are brother and sister, to promote the UK launch of his company, which sells disposable litter boxes and playhouses made from cardboard blocks.

They were followed by a support team, including a veterinarian, in a truck.

Thomas cycled most of the way, but was forced to ride in the truck for part of the journey near Colchester.

He said: ‘In the beginning it was all fine but in some spots it was too hilly to ride the bike and too dangerous for the cats. The hills were too steep.’

The ride was a last-minute idea as Thomas and his staff brainstormed ways to promote their ‘poop-up’ store in London, where the cats visited Trafalgar Square, the Palace of Westminster and St Paul’s Cathedral.

He said: ‘What is more Dutch than bringing the cats to London in a bike?’
