Maybe that time could be sooner that you think.Isn't one of you female carpets ~3.5' now? If you plan on adding all the hide and perching options you mentioned above, I'd imagine she'd be pretty happy in a 4' cage at that size. It may actually be good to "test run" your plans for your 4' cages with one animal before outfitting the rest of your cages. I know I'm glad it ended up working out that way here!
