beachbound-- i have a cat like that! he's supposed to be 3 and he acts like 6 months! he has shredded the casing on the front door telling me he wants to go out. we have a dog door (or as we call it the equal opportunity pet door) which works perfectly well, and that is how he and simon come into the house. BUT when it's time to go out simon taught him to go to the front door. hiss! now we will have to replace the trim with an indestructable product--maybe marble or steel. he also uses the loveseat for a nail sharpener. he's the first and only one to be destructive. good thing i love him! he also whisks around the place like his tail is on fire and jumps up and down on the furniture. then he'll come lie next to me and purr so sweetly. you'd never guess he was the maniac of only minutes before. lots of fun and love in them thar pets!
