I imagine every cat on the planet, particularly domestic cats, would unanimously say, if they could talk, that their favourite musician is deadmau5, purely based on the fact that deadmau5 is pronounced “dead mouse”.
I’m a fan of deadmau5 myself. Dunno if my boyfriend is as well. I’ll ask him sometime. Deadmau5’s music is amazing. I’m listening to deadmau5 – 2448 as I type this, and deadmau5 – Cat Thruster as I publish this.
