Cage Need help with cage design (incorporating pet store cage with C&C)

Well, I'm not quite sure but I have a little image in my mind. Make a platform of grids, I'm not sure how many and then test out the pet store cage on it. If it needs more support maybe put a grid coming downwards so that the bottom 2X4 would be partly sectioned off. You may need to section of more than once. But then you may not need to at all depending on how well it does on the platform. You can add things like a narrow wooden plank for strength or brooms? I'm pretty sure someone used the long handle of a long broom. I think if you put two narrow planks of wood crossing each other that should be quite strong. And then support it from the ground floor.

Once you can put it on and it definitely doesn't fall through you can see how to build a ramp up to it. I can't really visualize this part because I don't know what the pet store cage looks like. And I'm used to metric not inches. Hopefully you can stabalize it with lots of strong bits of equipment.
