I am at a loss of what to do. I have two cats, Jack and Elle, who are siblings from the same litter. They've been inseperable, always sleeping together or grooming each other.
Recently I adopted a 3 month old neutered kitten, Archie. I've kept him in a separate room and he seems to be getting along with the Jack when they've sniffed each other through the gate. Elle however has totally changed her personality. Once she got a scent of Archie, she immediately started growling, hissing, and lashing out at Jack. I was afraid they would really hurt each other since Jack didn't understand why she was being so aggressive and would try to get closer which would just antagonize her more. He would just stare at her and whine. They've been separated for about a week now, except for a few times Jack has slipped past me and ran into the bedroom. Not really much progress here. Still growling and hissing.
It makes me so sad to see him cry at the door. I get even sadder when I'm with Elle and she's her old sweet self.
I've brought Archie in the bedroom in his carrier and she just sat under the bed and gave a little hiss.
I expected tension between the new kitten and my older cats but I wasn't prepared for Jack and Elle to start fighting.
How do I fix this?
