Exel cages are on their way and should be listed again soon. I have asked Terry @ Exel to modify the cages in different ways. The newer models of the tower cages will be neat. They should extend all the way to the floor and have wheels directly on the cage, so more space and fewer accidents when moving. His next version of the tower cage will be 30x30 and hopefully 70+" tall which will be a HUGE increase in size per cage, plus, they will also have the option of connecting back to back to make a dbl wide cage. These will be usable for even larger animals such as maccaws and small primates.
And now to the point of this thread; the back to back cages will be quick disconnect and will be able to fit through a doorway individually for maintenance.
So, these will probably become my favorite cages in the near future.
Once the design is done, we may have to create a waiting list for them so he knows what to have built.
