Thor the kitten took a toy mouse up on the bed to play, and Izzy the cat heard the commotion and jumped up to investigate. They both then had to lay down and pretend the other didn’t exist, but I can see them earing each other. No, not earring, Spellcheck, ear-ing, verb, to point ears at another, not admitting existence, but keeping under audio observation. Very cat behavior. Should be a word.
