We've had to do some rearrangements and make some adjustments to the bird's area - because of Miss Molly, the dog who likes to knock things over to punish us when we leave

I'm sure I've said this is in the past, but the "bird room," or simply where their cages are, is technically a 3rd bedroom in the house, but it's in the middle of the house and had 2 doorways but just one door.
When we discovered that Molly would knock over the kitchen garbage can when we leave, we've been trying to Molly proof things and keep the bird's door closed and put up a baby gate to keep her out of the kitchen (and bird room, which is off the kitchen). Well, 2 (heavy duty) baby gates later and we've not successfully Molly-proofed yet. She has never given us an inkling that she'll mess with the bird cages, but we don't want to even make that an option if she gets realllly bored one day.
So yesterday we installed a 2nd door to the bird's room - and I'm lovin' it!!! My wheels are already turning with the new possibilities.....(and keep in mind that both doors are only closed when we're gone, Molly doesn't do anything remotely "bad" when we're home)
1) We had to rearrange the cages because if we left them as they were Lulu's cage would be behind the door when it's opened. So in order to rearrange we also de-cluttered a bit (always a good thing) - we have a small house and all the rooms except the kitchen and living room are pretty small. But this is the best room for the birds to be in.
2) With this de-cluttering and a recent conversation about some day getting the budgies a large flight cage to share, I can now see this more realistically as I was looking at what kind of space we had.
3) Having a 2nd door means we can now keep the birds more closed off when they're in bed if we happen to be up late. I'd always turn off the kitchen light when they're in bed and then hubby would turn it on if he'd go in the kitchen. Now they can be less disturbed.
4) This also means that they can potentially have more out of cage time - but this room is not nearly bird-proof so that they could be uncaged while we're gone. Our computer and gigantic computer desk is still in there and all kinds of things that Lulu would love to chew on I'm sure. But it has potential for, at the very least, times when I can get them out in their room and still have the mammals wandering around other parts of the house.
The budgies were absolutely CRAZED with all of this excitement and they flew so hard and fast last night - really wore themselves out. I think it's good for them though as they had gotten used to certain flight patterns and this had made them change things up and I could see their thought-process mid-air as they were navigating. All cages are now on different walls than they previously were so they've been navigating quite differently. It was a good mental exercise as well as physical.
