I checked out the rack made by Animal Plastics for the AE175 tubs. It was much more than I need with a heated room, but looks really nice with some great features.
I have an Economy model that has worked great so I sent an email earlier today asking if they could make a Economy model style rack that would hold three or four AE175 tubs. In true AP fashion I got a response just a bit ago. Unfortunately at this time they do not have the ability to do what I asked. As they have not tested a design to make sure such large tubs with large snakes would be safe. They said they do hope to get to it in the future but could not say when that may be.
I really like the look of the AE175 tubs and think they would be much better to house my Bloods in than the PVC cage my big girl is currently in. Her movements are just to big and hard to clean in her cage. A tub that could be removed and cleaned outside would be very welcomed by me. I may design myself a DIY rack that will fit my needs and put all four of my Bloods in their own rack.
Then I would have two open PVC cages. Now what to do about that!?!
