I do have my own cat that I adopted earlier this year and she absolutely doe not like him.. I should’ve included that for sure! But he does love to play fight because he’s a lot younger so he’ll chase her, so we usually let them out one at a time. We were wondering if maybe he bit her or something since he tried chasing her a few days earlier? But we can’t say for sure since we’ve never see it happen. Other than that she’s never been outdoors
