When I told Possum about my experience at the library (see previous post), he asked me why I didn't just put my ears back and hiss if someone was coming too close for comfort. "That's what I always do," he said. "Hissing may be a nonviolent deterrent but it always means business. Be sure to show off your teeth. If that doesn't work, you should growl, but that's most effective if you have a tail you can fluff up at the same time. And then if that fails, you can either flee or bite, scratch, and kick."
I agreed that he had a point, although humans look stupid putting their ears back because it takes both hands. But hissing probably would have done the job yesterday, although it would have freaked out everyone standing in line with me, too. When I said this to Possum, he shook his head. "They should have hissed with you in solidarity," he said. "I guess humans aren't as evolved as cats are."
No, we're not. Have you ever seen a cat with an overdue library book?
