Hi, I walked in the house the other night to my red devil going crazy, twitching and attacking the inside of his cave. It's the first time I've seen this and just wondered if it's a normal thing...... He only ever dose it when the lights are off so the video I have attached is not the best quality but you can still see him in action.
