I had never heard the word zoomie and my dictionary didn't know it either. A word which apparently didn't exist ! And even Google translate was very clear ! Zoomie meant zoomie in German and French, and that was it.
As usual when I don't know a thing, I google ! There I found two definitions. 1. (military, slang) A graduate of the United States Air Force Academy, and Cat zoomies. As I am allergic to all military things the second definition was the best ever !
As a servant to three cats and a cat lover in general I didn't know that when my cats are running around like pursued by the devil, jumping over armchairs, sofas, tables that I thought I have flying cats, then running around the living room and the kitchen, jumping in the air and then collapse for a nap somewhere !
When Rosie starts with her zoomies she gets a glint in her eyes, wiggle waggle her bottom and then start rapidly moving about, while meowing loudly but in a strange way.
Meanwhile we are used to it and find it rather funny to see our cat (one at time) flying through the room with a mad look on her or his face !
Rosie starts with an evil glance in her eyes
Arthur looks like an angel, before he starts running around and jumping into strange places or playing with the carpets.
Only 19 year old Kim does zoomies probably in her dreams. She spends 24 h in the bathroom with short interruptions !
