Just thought i would post an update on the situation.
Only after posting this thread did Candy attack Licky when it was feeding time. After seeing her actively go out of her way to get him. I refused to feed her til she calmed down. I stared at her and she lowered her head after a while. In which she came through the bedroom window (which is her normal thing, as our room was her area and Licky has now taken that over) Well she came in and wanted fuss and then curled up on my tummy and i seemed to have gotten her spot under her chin as she pretty much was falling asleep. After this, she seems to be coming in more than offen and likes attention off my bf, who she adores.
Licky is still being the alpha male of the house but the two of them seem to have worked some sort of friendship out. In that when it really throws it down with rain, Licky will sit on the window sill meowing til Candy pops her head in. He then moves over to let her through and give each other kisses and clean each other. It seems to have gone relatively back to normal but they seem far more comfortable with each other. They have even started to sleep close to each other again, when normally they sleep on different sofas.
I think its amazing that at the old age of 13 years old. These two siblings can work together, still care for each other and look out for each other.
Only the other day did candy miss judge the jump from the bed to the window sill and as a result was left hanging by her claws. When she finally let go and seemed to be a bit shocked, good Licky came to see what all the fuss was about.
Just got to hope the house move goes well now, as a few weeks without leaving the house will be hard, but its nice to think we wont have to split them up due to them not getting on.
