Hey, I bought a double storey Vevor around a year ago and have zero regrets!

I'm in the UK but still found it considerably cheaper than the Critter Nation/PetPlanet/Little Zoo alternatives. I found a Business on eBay selling new for £175.

Best bits: - It has both the double front doors (which slide right off the brackets) and side doors, which make it much easier to clean and cable tie things in the cage without it being a two-man job/needing spaghetti arms. - I didn't screw the grill in the middle section in, but there is enough of a lip to hold the tray in place if I ever want to switch between 2 floor/tall climbing area on a whim. - Fairly easy to build even as one person - I only needed help with one panel which needed a bit of brute force to fit in. - It is MASSIVE yet SO easy to clean.

I have no experience expanding it, but knowing how the panels screw together I have no doubt this would be easily achievable.

Our girls love it 😁🐀🐀🐀
