Hi all, First time posting so hope I'm in the right place. I have a lovely cat called Suki, she's been with me more 6 years and is such a bundle of joy, she's grumpy at times but mainly she's incredibly friendly and loves attention. I've recently moved in with my girlfriend (about 2 months now) and she's lost some confidence in herself and isn't as friendly as she once was. We've seen her sit with a cat outside and they both seemed friendly with each other so we've decided to get another cat, its a boy and he's just under 10 weeks old. We introduced them to each other today and inevitably there's some conflict, lots of hissing and a few swings of the paws but they've been separated. However Suki has been quite aggressive, if I go to pick her up, stroke her or put my face near her she hisses and earlier she actually attacked me. I'm just wondering how normal this behaviour is and if they'll eventually get used to each other? They both seemed scared of one another so Suki hasn't been too dominant.
