She is extremely hostile around guests. She will hiss and growl at them simply for being in the same room as them, even if they pay her no attention. We know this is because she is a extremely territorial cat and have tried a lot to get her to calm down. We bought them cat trees, litterboxes and even tried plug in sprays. But no matter what, she still hates them. What can I do to make her feel okay around guests?
She also becomes hostile towards me, who she is usually sweet around. Why? Does she think we are also a threat? Her moody behaviour will drag on for a week after the guests leave too.
