I think I accidentally conditioned my cat 😅 when I first got him as a kitten I was listening to bts chill music and the mix on YouTube that I used started with winter bear followed by sweet night. And he would sit in my lap and fall asleep. Now when ever he hears winter bear he goes to his bed and kneads his pillow and If I play sweet night he is asleep before the song fades out.
He is almost five months old and I am a routine person so it can’t be bad, the only time I use this power when it isn’t bed time is car rides so he doesn’t get anxious and when I have to give him a check up. Ears, mouth, feet, and belly, where he would normally scratch me.
I call my kitten bean so I play him winter bear on the piano and sing to him “sleep like a winter bean” and he is out like a light. Doesn’t matter how the song is played he sleeps. It’s magic.
TL;DR
V’s voice puts my kitten to sleep every single time.
