Cage Jumping piggies

[maddieg96]

So I have two males and one female. I am still working on the male habit, but they have the midwest guinea pig habit. my female, I only have one and she is still young, has a closed cage. I don't know what to do because my one brown male keeps jumping about 1.5 feet in the air and over the tall caging. How do I stop him from doing this? They are separated and I don't want to keep worrying about them while I'm at work and sleeping.

Closet shelving makes an awesome cage lid. You can buy it at any home improvement store.
