Hamster is scared of thunder!?

Thank you for a lot of comments for my chubby chubby buddy, Cake. -----About Cake’s Housing Environment----- We live in a tropical country and have squalls every day, Cake is used to the sound of thunder, but on this day, lightning suddenly struck near our house, startling him and making him jump out. Since we are living in tropical country, we use organic pest control but ants still can get in sometimes. His cage is 50cmX30cmX27cm, the biggest size we can find here. Well, the cage is not big enough , so there is a cardboard playground for him to play on. Please check this movie too!
