Just wondering because any time I’ve played with my cat I’ve never in my life heard her hiss. But recently my dad has been visiting from out of state and he seems to really enjoy the cat, and typically chooses to play pretty rough with her. I’ve noticed that she hisses at him a lot while they play. At first I was a little concerned because I don’t want her to be stressed out, but at the same time she 100% has the option to stop playing and just leave the room, and she never does, she just keeps playing. Is this behavior fine or is she genuinely upset??
