Ed Lilly of Constrictors NW made this for me. The plastic is HDPE. Ed no longer makes cages. I decked this out and it has housed different snakes over the years.
Currently my boa is using it.
The first photos are from the build.
All the decor is easily removed for cleaning.
I used LED strip lights in this cage.
All of the caging is shown here. The right side is made up of three 4 foot cages of different depth and height dimensions.
This comfortably held a 9 foot retic, an 8 foot coastal carpet and now a near 7 foot boa.
It certainly isn't the largest cage, however I consider caging that is 6 feet wide or more to be in the BIG category.
