I have 3 inside cats. Two originals. One tamed feral. The "feral" has been inside the house for about 8 years now. One of the originals loves her. The other would like to eat her. We keep them separate when we are not at home.I'm 6 months into my fiasco. The two kittens are still working on the Queen. I don't think she's gonna ever give in. I never knew how fickle cats can be about new cats.
