The population of hedgehogs has declined by a third in the last 20 years.
Hedgehogs love gardens but sometimes access into them can be difficult.
As part of Hedgehog Awareness Week, Cambridge City Council have launched a campaign to help protect our prickly friends.
Over the week, they're visiting homes across Cambridge and creating 'Hedgehog Highways' in gardens.
These are holes, the size of a small football or CD, which are drilled into a fence.
This enables hedgehogs to pass through from garden to garden.
"Gardens are a fantastic habitat for hedgehogs but an individual garden is often too small, they need to be able to move between various different areas", said Guy Belcher, who is a Bio-diversity officer at Cambridge City Council.
"What we have done is start to link gardens so if everyone made a hole in their fence or in their wall or just leave a gap under their gate suddenly we have a much wider area that hedgehogs can forage and hide away in."
Every night hedgehogs travel around one mile looking for food and mating partners, but fencing off our gardens makes it harder for them to do this.
The council is aiming to speak to as many residents as possible about how they can make improvements to their gardens to help hedgehogs thrive.
How can you help the hogs?
