Yesterday I had my best friend over, something I haven't done in a while because of our conflicting schedules. When she bent down to say hi to Wobbles, she outright ATTACKED her! She's never shown aggression to any human being in her life, not once, not even with total strangers. But multiple times she put her head down, hissed, and charged! She even got a good nip on her ankle. It's just so bizarre. Wobbles has seen Fiona before, albeit a month or so ago. She was totally fine then. What the heck happened?
