Wedge the tunnel in place by the sides so that it does not roll around, and place one end in a pile of hay for your guinea pig to hide in and explore.
Alternatively you can place some vegetable and lettuce inside the toilet roll to tempt your guinea pig.
Create 2-3 dead ends in the maze, depending on how big your base is.
Place a large reward consisting of vegetables, forage mix, hay, and commercial treats at the end of the maze.
The idea of this toy is to have your guinea pig forage and try to find the treat hidden in the box.
Apple, carrots, and cucumbers make great treats.
Vegetables would be a healthier alternative for your guinea pig as commercial treats have a high sugar content.
