Nesrin Erhan, who rescued Boo as a stray on the streets of Turkey with her husband, says she's as surprised as anyone over her cat's apparent hatred for the feline-centric music.
"Actually, he's a very calm cat. A calm, fat, sleepy cat," Erhan told The Dodo. "But when we try this 'calming music' he gets mad. We first tried this on our TV. We just played it for fun and wanted to see what was going to happen. Boo was sleeping on the couch, and he suddenly opened his eyes and attacked the screen."
They decided to test it out again later. Boo's reaction was the same.
