I adopted a second cat a couple of weeks ago named Luna. She is 4 months old and very playful. My other (boy) cat Detective Oreo is almost 2 and he is also playful. I have done all the right introductions- site swapping, feedings coordinated, scent swapping, etc. They can eat together, next to each other and even occasionally be on the condo at the same time and just hang for a minute. Sometimes they play with each others paws under the door since I keep her separated from him when I am not home to watch them. The major issue is that Detective wont stop jumping her and wrestling with her. She is about 4 pounds and he is 12 pounds of pure muscle so that makes me worried. She definitely starts it some of the time in that she'll tag him and then run away which leads to him chasing her then wrestling her. He is just so much bigger than her and she is SO LOUD. She meows loudly when they are wrestling. I don't know if I should break it up or not. They also do this every time they see each other. is this actual fighting or are they playing? Should I restart the introduction process?
