I brought mine on eBay, it's a 2x4 which houses 2 boars, they love it and so do!
It's great seeing them have so much room to run around, I love getting different liners for it and beds (although that can become addictive!) and it's easy to clean.
I possibly paid more than if I'd sourced grids and correx separately but it was easy and still cheaper than a shop brought cage and twice the size.
That's awesome! Is it sturdy! I will have to move mine out of the spare room when we have guests over, and I have 2 cats that might want to sit on the roof! So it needs to hold up to those things!
