I will have to go back through, but i assume we are the only acrylic setup!
My SO has OCT and struggled with adjusting to bird mess. I had this customized and we are all happier for it! We have multiple cats, so it works well as a barrier for them as well. They are out of cage frequently, just not with the door open for safety.
The top is mesh and the lid lifts off. The girls took adjusting to coming out the top of the cage instead of a door, but quickly became acustomed. We also don't deal with biting through the bars.
