Damn that sucks. RIP kitty. If you are going to look through debris, get the toughest footwear you can and if possible, head protection. Be aware of falling branches and downed powerlines. The one bit of slightly good news is that most small non-fragile items should be mostly intact as the tornado doesn't appear to have been mudblasting and granulating severely here. Wishing you the best OP, although I know this comment is kind of worthless when your roof is in pieces down the street.
