We have had Jazzy since she was a puppy. We have a semi-large family, and have had a houseful of people on a regular basis since she moved in.
She has never had problem with visitors, and has always been ready to greet everyone as they enter, and usually is able to sucker guests into letting her curl up in their laps for a cozy nap.
Lately, however, she seems to be uncomfortable with visitors. She seems to prefer having just her family home {with the exception of a few neighborhood kids, whom she also views as belonging to her "pack"}. When visitors come over, she wanders about with her tail uncurled, looking uncomfortable. She does not try to get into laps, etc. and Saturday gave a little "I'm not comfortable with this" growl when a friend rubbed her tummy – usually a favorite.
Any ideas on why this is going on? I am aware of nothing happening to affect a change like this.
