My bedroom is in the basement and when we first moved into this house she refused to leave it, no matter what. She might venture into the hallway but nowhere else. Then, for about a week, she'd go upstairs with us when we went and explore a bit, but then go back down. Now she refuses to go into the bedroom. If we put her in there, she complains and scratches the door until we let her out. As far as I'm aware, nothing has changed. The biggest issue is the fact that her litterbox and food is down there. She won't even go down there for food. Alice isn't acting any different, it's just Sibyl. Is she just sick of that room? Has anyone else had a cat do weird things like this?
