Store cage substitute.

[PeanutPets]

I'm ashamed to say this, but my rabbits currently live in large store bought cages. Before you attack me, I understand its bad. I want to change that.
So let me explain, we have these cages because my parents brought them and we don't have much space for a cage.
Is there a a type of cage we could use that is cheap, doesn't take up a lot of space, and I can easily find?

You can use a modular enclosure that you can adapt to your room and that doesn't take up a lot of space, and then you can enlarge it to give your rabbits more space.
You can find them on his site if I remember well:
