Pressure washing

So hubby brings this huge loud thing home and wants me to clean the deck, 4 hrs later and now I am convinced I have carpal tunnel in my right wrist, it looks a little better, I had forgotten how it looked years ago pre-weather. So Jasper and TD are outside with us carrying on, fighting and getting so dirty, Jasper however is not so afraid of the blower or the pressure washer. I noticed him jumping almost over the 6 ft fence eating bamboo leaves. DO I not give him enough fiber in his diet??? Why is he eating the bark off of the tree also? I saw him do it, TD was never like that. I think Japser is adopted!~
