Askme: Help my cats get along →[More:]Between my wife and I, we have five cats, integrating the two cat groups has been mostly uneventful. Unfortunately, for some reason, one of my cats scares the crap out of one of my wife's cats.
Edison (the little rascal, age 2) will run into the bedroom where Cider (age 12), and chase her under the bed or dress. He doesn't wrestle with her or anything, but he'll take swipes at her with his paw. She has taken to living under the bed and dresser in response (though she's always been somewhat shy). When Edison comes by, she hisses with incredible intensity.
Edison has seemed unimpressed by hissing in general (except when I do it), it may be related to the fact that he was rescued from a home with 30+ cats when he was younger.
My wife is getting really worried for Cider's health since she is a bit older. Do you bunnies have any tricks for helping cats get along?
