Do you have that one friend who sits and complains about everything and you just want to sneak up behind them and give them a good smack on the back of the head? If so, this must be the cat version of that sentiment. 

Lucifer, the cat hiding inside the cupboard, reaches its paw out and attacks its feline friend that appears to be growling about something. 

Well played little Lucifer. Your name fits you well.
