This always freaks me out.My oldest cat had always howled at imaginary things on the walls or ceiling when she gets in a playful mood.
She gives them hisses as well. That cracks me up.This always freaks me out.
When you say hallway, is it by any chance near your front door to your home? Or another closed door to a room she doesn't have access to?Yeah it's only in the hallway. Thank you guys for the help!
