Hi, we have a girl cat aged one and a kitten also a girl aged 7 weeks. Initially there was hissing and yowling when they met but they can now be in the same room and will eat alongside one another quite happily, no agression around food at all. But mostly they chase one another and fight, silently, no hissing, ears are forward and claws don't seem to be out. Just worried because the kitten is so much smaller than the cat - although she seems to give as good as she gets, and chases the older cat, she does occasionally give out a little squeak as if she is in pain, at which point I tend to step in and separate them. I always separate them at night and if we go out but am wondering about other times - do we just let them get on with it or try and stop the fighting? I am wondering if eventually they will both just get tired and go to sleep! Thx.
