Confront one. Stamp your feet and growl. Then write back how you could tell just before you got sprayed. Enjoy spending your winter in a tent!

Actually I've never seen one mad at me. I've sat down within 5 feet of them as they grazed for violets on my lawn. No problem. They would look at me and I at them. They would go back to eating. One of my cats, on the other hand, didn't do as well. He came in coated yellow from the spray (butyl mercaptan) all down his formerly white front. He was finally banished to a room with burning incense.
