So we just got a new kitten five months old for days ago we already have a two-year-old cat. Both are female. I already know I have not done the best job when it comes to introducing them both because they will be in the same room and I’ll play with them. Besides play time each of them has their own room with their litter box their food bowls their beds and toys them completely separated at night. So when we first brought the new kitten home there was a lot of hissing very grumpy two-year-old cat and all she wanted to do was go downstairs and leave the situation, The new kitten is not afraid of the new situation she’s not hiding she’s playful and has no issue with my older cat hissing at her she will just stop what she’s doing and back away from my older cat so she’s being respectful and not coming at her. But I’ve noticed today while they were both playing with their own toys that my older two-year-old cat would stop her playing and chase after the kitten and just stare at her. there hasn’t been any hissing when my older cat is running toward the kitten the only thing is is she puts her paw up like she wants to swipe but never does and so I’m assuming that’s aggression towards the kitten and not being playful so how should I re-introduce them because I feel like I started off on a bad note with the older cat I’m just trying to create a better beginning . My older cat doesn’t hiss as much as she did when we first brought the kitten home and when she sees the kitten and goes into the kittens room she’ll sniff around she’ll try to sniff the kitten and won’t really have any issues she might growl a little bit but nothing else. I’m not sure if that means she’s getting used to the cat and things will be fine and I just need keep doing what I’m doing or should I try to re-introduce them and if so how do I reintroduce them even though they both know that they’re in the same house and it was bad to begin with. I need help please
