Greetings. Our kittens, Poppy and Oreo, have gone from "ewwwww hisshissshisshiss" (<- Poppy 100% of the time when Oreo came home) to "Hey, let's engage in rough play!!!" It's hard for the family to watch because this is the first time we've had two cats. Can anyone offer any behavior attitudes to watch out for that emphasize that we have to separate the kittens? My friend says the most important is to watch and see if either of the kittens run away quickly, thus ending the fight. And others but i can't recall. See, the youngest is Oreo and he's timid, and not as quick as Poppy, and he sometimes yowls. So I pick him up and move him, and he goes right back to Poppy. There's no hisses, spits or growls during rough play.
