Forgot to mention:
During my riding lesson last week we were attacked by one of the barn cats as we were trotting around the arena. On our first pass, she just rolled around in the sand by the rail. And on the next pass, where I decided to ignore her so Copenhagen wouldn’t freak out, she leapt out at us. I missed it entirely, and Copenhagen (good boy!) followed my lead. Our instructor decided that was Enough, however, and removed said cat from the barn. Crazy cat.
