Is he still packing? If so, then he is possessed by at least two demons...Seriously, tap him lightly and hiss sharply whenever he crosses the line. If he challenges you then hiss louder and longer. If he still challenges you, give him the house and you leave because you have adopted a tiger, not a cat.
Nope, he’s fixed.
Hey cats, I pay the mortgage around here and carry out the trash. I am almost at the top of the food chain.
