Occasionally, it's really obvious that she's just playing. Her tail will be straight up in the air, ears will be happily perked, and she'll back off immediately once the kitten makes it clear she's too overwhelmed to play. But there's other times that I've noticed where she'll full on wail on her with no real consideration of the fact she's clearly scared. Is there a way to discourage this behavior? I make sure to separate them whenever it happens, but my older cat has about 8 pounds on my kitten right now, and I don't think she fully realizes the size advantage she has.
