Other
common stress and anxiety triggers include moving, travel, disruptions to routine or the familiar environment (as with renovations or new furniture), unpleasant
noises (maybe there's construction across the street), the loss or addition of a human or animal family member, separation anxiety when the
house is empty for prolonged periods, and seeing cats or prey animals outside but being unable to get to them.
Common stimuli that trigger redirected aggression include loud
noises, seeing an outdoor or stray cat through a window, or an altercation with another cat in the
house.
