Contact the ASPCA or even firefighters. They WILL rescue or at least give your birds water if they won't let you return. If it were me I would just go around the roadblocks, but that is me there is little that fazes me once I have my mind set. I hope your house makes it. I have two friends already that lost everything. One of those was made worse by the Moms bad planning, she took all her/daughters CD collection all 10,000 cds and didn't have time for the heirlooms or computer (the computer is replaceable until she remembered just how much she had on it). They lost everything, heirlooms passed down 5 generations gone for stupid CDs. As much as I want to call her out on it, she has already been through enough. Like someone said hindsight is 20/20.
I also have a friend that had a miracle house. His and one of his neighbors are the only ones that made it in that whole area, AMAZING!

PS They caught two arsonists today. One was shot and killed, he should have stayed in Arizona.
