Hazel has to be careful. If she gets too excited about something and moves too quickly, Olive senses the excitement and mistakes it for playtime.
It usually happens when I get home and Hazel comes running to see me (yes, some cats actually do that). Olive immediately comes running and leaps over the top of her and sometimes even makes a 180 degree turn, runs back and jumps over her again.
Of course Hazel hates this and will have to slow down and “army crawl” on her belly so that Olive loses interest. It usually works since Olive has such a short attention span.
