So let me do a small narration on behalf of the cats for you.
Trouble(orange cat): "I'll just just sit here for a minute and pretend that I don't see him. Then I'll attack!"
Yoda(gray cat): "Oh great....now what's he going to do? He better get off my spot on this couch or else!"
Trouble: "Aaaa-neey minute now....not yet, not yet..."
Yoda: "That's it....(notice the ears are back..) I'm outta here! He's too annoying!"
Basically, that's how it goes with these two. Trouble gets bored and takes off after Yoda. Yoda gets mad and growls and hisses at Trouble. After a little race around the townhouse, Trouble finally gets distracted by one of their toys or whatever I happen to be doing! On it goes.....like two siblings! I'll call them "Sandy and Kevin."
