Thank you for the kind words! The enclosures look a lot more involved and complicated than they really are. Open the doors and everything can be removed in a matter of seconds. I had a feeling you were referring to SED about the perches. Not cheap, but honestly not outrageous either. I like that they can be easily cleaned and are lightweight. I have an older version of the large perch holders in my lowest enclosures and a handful of his tub perches as well. Love them all and so do all of my critters. Definitely will consider the portals for lightweight budget friendly enclosures in the future if needed, I like the idea behind those a whole lot.
