As a general rule, we say that Furnishables are designed specifically for glass enclosures. However, they do stick to some non-porous plastics, however we can never guarantee how well. Unfortunately we do not offer refunds if they do not stick to a plastic cage, so please be aware of this before purchasing.
It is important that you keep them flat and do not lay them directly on top of one another. It is best to keep the paper backing that they arrive on and restick when not in use. We have a handy storage solution coming soon; so stay tuned.
