That sounds like my kittens and my calico. Gizmo is the top cat and thinks she must remind everyone of it at least once a day. The older cats know to stear clear of her when they are walking by but the kittens have not learned yet. They attack her tail when it twitches and she tolerates it for quite awhile which surprises me. Then out of now where a kitten will walk by her and she will swat him a good one, almost to say "remember yesterday when you played with my tail well here is payback"
The other day Bob (kitten) was playing near her and she kept staring at him like "why are you not afraid of me" the look on her face was pure shock that this kitten would dare invade her space. He kept playing and glancing at her until she leaped on him and gave him a nip on the back of the neck. She jumped right off when I yelled at her and then she looked at me like "well he was not kneeling to the queen" I laughed so hard at her. I even laughed more at Bobs expression. He was like "what I do?" It didn't even phase him. He kept right on playing and she walked away in disgust.
I think it will take time but they will get along fine. I think Pixel just needs time to adjust and it sounds like it is going fine.
