Thank you all for your advice!
Unfortunately the bathroom isnt an option - its not called the smallest room in the house for nothing in my case!!
so we are continuing with the cage - and so far so good! Bitza is in his cage all night, and when Im at work - although i could shut him in the livingroom (where his cage is ) - at the moment I dont want to excude Rocky from any part of his Empire!
Rocky checked out Bitza's cage yesterday evening when Bitza was flaked out on the sofa - he then sniffed Bitza's paw - which seems to be a step forward! Bitza is so laid back - he seems happy to accept Rocky is the Alpha cat - Just need Rocky to realise that!
Needless to say we are lavishing attention on Rocky - even when he doesnt want it! He is still hissing when he walks past Bitza - but Im hoping this will slowly stop - the only reaction he gets to it is from us!
I guess the next step will be in a couple of weeks when Bitza is allowed outside (though he doesnt show much interest in going out at the moment!) - and I can unlock the cat flap - currently incoming only when he is loose...poor Rocky has headbutted it a couple of times - and voiced his disapproval in no uncertain terms!!
I must admit that, once we had made the decision to take on another rescue cat, I did start to have major misgivings and worries - most of which, I happy to say, have been totally unfounded!
Thanks again Rx
ps - have been trying to upload pics but they are too big!!
