Feline of the Opera - Opera Cat Sings Phantom of the Opera Christine Cat takes center stage with her hauntingly beautiful meow in this rendition of Phantom of the Opera. As she pours out the iconic refrain, Phantom Cat utters one chilling word: “Sing.” He’s obsessed not with world domination… just her voice. Some felines chase mice. Others chase music. If you're not crying or laughing by the end, check your pulse. Or your fur. #phantomoftheopera #opera #funnyvideos #cutecats #catlover | Maged M
