In the documentary "Young and homeless", the BBC's Stacey Dooley follows some of all young homeless people in the UK, while struggling to get the legal side of life. Cat and Shelby are two of them.

- It's good to have friends as homeless. You get togetherness, a family. A homemade family, says Shelby.

Last year, around 100,000 young people were estimated to be homeless or at risk of becoming homeless in the UK. But there may be even more.

Living in hidden homelessness

Cat and Shelby couch surfers, staying with friends or trying to manage on their own. They live in what is called "hidden homelessness" and therefore do not end up in the system.

There have been nights when they have had no alternative but the streets, but rather they wander around.

- People steal from one if you sleep, says Cat.

- Everyone steals from each other. Everyone gets to do it here. It's not good at all, it's dangerous, Shelby fills in.

Tested support housing

Cat was convinced that the housing was worse than living on the street - until she tried to live in one.

- If I had known about these places before, I would have asked for help a long time ago, not avoided the system, she says.

In the documentary "Young and Homeless", Stacey Dooley follows four of the UK's homeless youth for nine months. Watch the entire documentary on SVT Play.
