I've had Shadow and Whisper for almost five years now and as they've gotten older the sibling rivalry has gotten worse. He attacks her several times throughout the day/night and she always has to run to where I am to "save" her. It got so bad the other night I had close the door to our bedroom to keep him off her.

I love my Whisper boy and I hate the idea of him afraid of me but I'm always yelling at him, squirting him with water, chasing him out of whatever room I'm in if she runs to be rescued. He's so sweet to Callie and everyone else and I know he is just trying to show his dominance over his sister but I'm beyond irritated at this point.

It's also not fair to Shadow as she is always having to be kept enclosed in whatever room I'm in to get him away from her. She does try to attack him but isn't very successful as he always ends up chasing her right back.

I don't know if you have any suggestions. I've tried the water squirting, keeping them seperated, whatever and would just like a way to remedy the situation. Shadow should not have to be scared to walk around in her own house.
