We have six cats and have to spell in front of them in some cases.
Wow that’s crazy, but neat. I have never seen that in my house, and I have actively tried to get my cats to respond to verbal communication. If you say their name they will look at you, or come to the room, but that’s about it. I can even go into the kitchen and grab a bag of anything at all and move it around, but if I so much as bump a bag of their treats they come running lol.
