Well if he's having a 'Blue Day', i am none the wiser. He's at home alone again. Yesterday, I think he spent five and a half hours just laying on the bed. When i left him to go to work, he was under the covers. I came home and he was just sitting there waiting for pets. I haven't seen him JUMP on the bed in months. I announce 'Elevator' and lift him to snuggle at night. We tried steps, but he wasn't having it.
