Playing or fighting?
One year ago we adopted Luna (grey, 2 yrs old) to keep our older cat Haru (black, 11 years old) company. We introduced them really well I think. It was very slowly over about a week or two following the steps correctly. They went from hissing at each other from either side of the door to now mostly tolerating each other lol. It’s been about a year and they’re still like this sometimes and I’m not sure if they’re playing or fighting. Most of the time they keep to themselves and do sometimes sleep next to each other on our bed or chase each other around playfully, but then sometimes Luna gets too playful and just attacks Haru like this. What do you guys think?
