Hi, does anyone have any tips on how to help our cats get along better (or at least tolerate eachother)? My neighbours have a young cat that they've recently started letting out and every time my cat sees her in the back garden he chases her and swipes at her. Not in a playful way either :( When I catch him doing this I bring him straight in as I feel bad for the girl cat as she's still a baby really, about 6 months old. Mine is 2 years old.
I just worry about my cat hurting her when I'm not at home to keep an eye on them.
