My dear (oh dear dear dear) Henry Cavill…

...next time, what about an Emotional Support CAT??? I'm available for medium and long flights and here's how it works: you cuddle, I purr, you relax! It's purrrfect!!! 

«Superman can famously fly faster than a speeding bullet – but the British actor who plays the superhero needs an ‘emotional support dog’ to board a plane. "Man Of Steel" star Henry Cavill was seen arriving for a flight at Los Angeles’ LAX airport with his dog, which was wearing a vest with the words ‘Working. Do not pet. Emotional Support Dog’ emblazoned on it. Under a unique US Department of Transportation rule, passengers are allowed to take their dogs on flights if they have a doctor’s letter stating the animal ‘is necessary to their mental health or treatment’. Cavill’s fellow Hollywood star Ryan Gosling also has a doctor’s note allowing his dog George to fly with him. Cavill bought his dog Kal-El – who was named after Superman’s own name on his home planet Krypton – last year with his then girlfriend, American actress Gina Carano.» in Daily Mail
