There are lots of different “how to’s” on the web about how to make different kinds of homes. with lemony, ours was a work in progress. we built the basic structure (with grids)) around his purple cage (i think we have the same one). we wanted to keep the cage because he seemed attached to it. since he likes to jump on top of his cage, we made this a part of it as well, putting grass mats over the top of it so he didn’t hurt his little feet. our third level just consists of a roost made of the grids. on the bottom of that we put a towel and another mat. he can jump from the top of his cage onto the roost – he seems to like it a lot. the roost is right by the head level of our bed, and he likes to sleep up there. i like to think he likes to be closer to us.
we also took lots of trips to home depot just to “browse.” It was at this point that i decided on the grids – there are only so many times you can walk up and down those isles, and it’s not like we have a garage filled with tools in our studio apartment to construct a mega monster cage. but lems likes his – i think it’s just right for now.
good luck! and improvise!
