That cat didn't look playful when he was following her around, tbh. It's hard to see from the video, but I think his body language showed he was a bit mad.
Cats are very chill. They really don't care about what others do and they understand who treats them well and who doesn't. And even if you pamper and spoil the cat, if they don't like you, they they won't go to you. At most, they "respect" you if you bring them food and understand do not mess up with the person who carries the food tray, but that's it. They don't feel obligated to show them any gratitude like a dog would.
This stupid thot knows her pets have zero discipline. Or rather, I doubt she understand pets need discipline, she just expects them to do random shit on camera and she's ok with that. They are props to her and she does the minimal to keep them alive. Like many have said, this could be solved by locking them while she streams. And also, as others have pointed out, she has zero interaction with them, it seems. They don't know how to respect her and she thinks it's funny. It's exactly like those parents who think it's "cute" their child just pooped in front of everybody and neither help him or exercise any discipline.
