I was desperate to get a playstand but everything is just so expensive and i needed to save up for a bigger cage which was needed more, so i actually got this idea of the fab Ryelle a while ago as her irn likes her clothes dryer.
I decided i would buy one of these
Its made from pine wood
and this was the result
Its had things added, moved and and taken off but you get the idea
It is great all my fids love it i just need to attach the bottom of it to a big base to make it more steady and wipeable and add some more toys
, that is a good idea in your situation, due to you needing to save money for a new cage.
