Okay so we are now 6 weeks down the line with the terrible two.8 mth old female kitten and 2 yr old stray female tabby who adopted us in November. From early on we realised that it is clearly kitten who is the aggressor and initiates the fights but it is still non-bloody -stop[shock].Stray is lovely ,docile affectionate creature and I am so fond of her but kitten will not let up.It goes like this non stop...cat minding her own business and kitten creeps up and lunges at her with her paw and then cat reacts and chases her and lots of hissing etc.After too much of this big cat then chases kitten and corners her on the stairs/against a wall and smacks her with her paw.Then even when kitten is clearly frightened by this she [kitten] will immediately run after big cat again and so it goes on and on.If they are simply left to get on with it upstairs all you can hear downstairs is constant scurrying across the floorboards chasing each other. They sleep in each others beds and eat from each others bowls and use each others litter trays during the day. I separate them at night and if I am going out. Any thoughts please experts as in will this ever stop?Does it sound like it will always be like this or will we simply persevere?Its horrible for everyone now.[sad]. Sorry ,I feel like I am always here asking the same question but I honestly would have expected things to be fairly ok by now. I don't know if its better to let them sort it out themselves or keep trying as much as possible to keep them apart[hmm].
