He probably will - he'll be cheesed off at the thought of some little weed muscling in on his patch.
He's been top cat up to now.
What sort of personality does Bane have ordinarily? That will help to deterrmine what is "normal" for him. Some cats dont get hissy or growl. Other cats do, but when faced, just turn tail and exit a room. Some cats just stay away from any kind of meeting or confrontation, and that can be the hardest reaction to resolve.
The best thing to try if the growling persists, or the turning tail and scarpering, or if fisticuffs seem to be the order of the day, is to engineer matters, such as with scent swapping and site swapping (where Bane gets to spend some time in Harvey's room, and vice-versa, without the other one being around in that room too) and then feeding at the same time on either side of a closed door, gradually leaving a gap in the door between the two. Alternatively engaging them in mutual play together.
That one took a bit of time in our house. Tinks wouldnt play. He was a "steer clear of the whole situation" kind of a guy. You could see he wanted to play, but at first he wouldn't. He'd scarper. Eventually though, he couldnt resist. We ended up at one stage with two wand toys on the go. OH wolld play with one of them, and me with the other, and have them together in the same room. (and our living room is tiny, so all ornaments and the like had to be put away for the duration!)
We were fortunate though, inasmuch as Moray was an incredibly sensible kitten, and could sense when to make a move, and what kind of move to make. He played the long game - he was a patient kitten. (Knew he had to be if he was "gonna be allowed to stay"
) [And there was a stage very early in when we thought he wasn't going to stay - my OH was being particularly devastated at Tinks' disappearing act and was all for giving up, but I managed to kick that one into the long grass, and persuaded him to try a different approach with the help of our Purrs family on here
