So I took in a stray. Been caring for her outside for 3 months. She is very sweet and loving. I am actually rather surprised how well she made the transition to becoming an indoor only cat. Purs all the time, rolls on her back for me to pet her belly. The only problem is I have two 9 year old cats. They both have been curious, and my female cat has stayed her distance, but will occationally hiss at her. My bigger concern though is the new cat swats and trys to hit my cats sometimes. She had her spay surgery on thursday, and today she was much more active so I think with her feeling better, she is getting back to her old ways, maybe acting out her instinct and defending herself from other cats. Today when she saw my male cat come walk over to me she ran towards him and went to swat at him in a much more aggressive way then I had seen before. For those who have introduced new cats did the cats eventually get along? I don't mind if they won't ever be buddy buddy, but I don't want her to always hit and attack them, as my two cats never ever fight. I did read on other websites that hissing and swatting initially is normal. As long as she doesn't take out her claws or bite I'm not super worried either. Thanks
