From a social media website, the band wrote this about the song:
"We were crashing at a friend's living room in London and came home from a night-out. All we wanted was a good night's sleep but our friend's Spanish roommate was still up and smoking with his girlfriend. He was obsessed with this crazy idea that everybody should call him "el lobo" (That's spanish for "the wolf"). He really could NOT let it go haha. He went on and on about it and eventually started assigning animals to every roommate: We had el gato/the cat .
