I have 2 sister cats, coming up to 3 years of age and they've always been best friends. About 4 months ago one of them started wondering off and hardly ever comes home. When she does come home, it is clear she is extremely scared by her sister, who does keep cornering her and fighting. Also when she is home, she goes to one room in the house, stays there for about a day, then we won't see her again for another 3-4 days. She has also become really timid and scared with us now too when used to be such a friendly sociable cat. We had an older cat that died around the time she started to wonder off....It doesn't seem like this has anything to do with it but perhaps it could?
Why has this happened? Is there anything I can do?
