Whew! We awoke this morning to more snarls and hisses. I was admittedly frustrated at that point. But we carried on with our morning routine, which includes Henry "helping" DH read the newspaper. And by "helping" I mean that he licks it, swats at it and otherwise makes reading a PITA. For whatever reason, Izzy started to relax at that point. She started voluntarily approaching him and touching noses. Now she's back to pestering him like normal.

At least I know what to expect now if Henry goes to the vet. Thanks for all the advice. Now if it would just stop raining so we could go camping.
