Hi all, I have joined today to ask a question around my cat's behaviour She is around 8yrs old, a rescue with a nervous disposition. We've had her for 5yrs. Sometimes during the night she wakes us up by coming into the bedroom crying. I say crying because it's a really hollow and sad sounding yowl, not like any noise she makes during the day time. She won't stop until she's comforted- sometimes calling out to her works, but sometimes I have to get out of bed and fuss her. The first time she ever did this was after we left her alone overnight for the first time, but she now does it on and off even when we haven't been away. Is this just nervous behaviour, her wanting to reassure herself that we are still here? Or something else? She is clearly wanting us as she comes into the bedroom to do it, she's not yowling out of the window at other cats or anything (she hates other cats). She isn't asking for food or asking to play as she has specific behaviours for that. I'm concerned that she does this when we're away and gets distressed if she doesn't get a response. Breaks my heart to think of my little girl upset and scared. Any ideas as to what this behaviour is about?
