I didn't catch up on the last page of the thread, so I apologize if I am repeating something that was already said.
The rags soaked in ammonia is actually a very GOOD idea, although it might repel your own cat as well. Cats are VERY sensitive to ammonia. My old chiropractor ran a sanctuary for large cats, and he had a lot of them. Several mountain lions, bobcats, caracals and 8 large tigers. They were all handled regularly and daily, and some were on the aggressive side. The ONLY form of discipline he used with them was a regular old squirt bottle with a mixture of water and ammonia. Those tigers would bound at him when he entered their enclosures to clean, he's squirt that bottle in their direction and they'd take off in the opposite direction every time. Then they'd pace around the back of the pen with their mouths hanging open, they REALLY hated the ammonia.
