Thanks for motivating me to finish my patio!
I decided to use one U shaped grid and one flat grid to make the entire patio and ramp removable/adjustable. If I decide to convert this to a full loft I just have to extend the ramp. It ended up on an easy enough incline that I didn't bother with the cave idea. Now that it is all together, something I didn't realize is that that if you don't use a cover (I have one so it wasn't a problem), you will need one. I think she could probably jump right out of the cage so at the least, the patio section will need a lid.
Here is how I did it:
I bent a grid into a U shape and tie wrapped it to a flat grid. I laid the flat grid on top of two miracle bars (from the cage store) and used a carabiner clip for the grid so it is removable for cleaning:
I laid down ramp carpet tread (also from the cage store) on the ramp and into the patio:
Then put in a home made fleece flipper:
I ended up switching the plush bed above out for a fleece bed because she was chewing on it more than I'd like:
She loves the patio, she loves the tunnel and bed and started using the ramp immediately.
I do regret that when I cut the hole for the ramp I wish I had cut it down the middle and created two swing out doors so that that little bit of opening was blocked off. I think I will be adding two wings to this area to make it a little safer even though it is only 5 squares off the ground. I have seen other people leave their ramps like this but I think it would have been nicer with the flaps extending to the ramp.
