What are your cats like when you have visitors?

[TheWinterOne]

My two are great with all members of the household but they will not go near any friends who visit. Even when they visit frequently. Both seem to either opt to go in to hiding or my male will decide now is best to go out. My girl didn't have the going out option because she wasn't spayed until last week.

Our tabby of feral stock slinks straight out of the cat flap, our black monster sits on the arm of their chair and glares at them, especially if they are eating.
