The vacuum monster is much feared at my house. Ophelia just runs and hides. Trent is my brave boy, my guard cat. He hisses and swats at the monster, then jumps back as far as he can until he gets brave enough to do it again. What's so funny about it is that he has the wimpiest little hiss you've ever heard. Sounds like someone breathing! He also hisses and growls at people outside the window coming up to our door - even me and hubby! Quite the guard cat I have!
