I'm completely worn out. Stella has escaped the apartment twice in the past hour. The first time she stayed on the third floor and it was easy to catch her. She escaped while I was wrestling with the door, my cane, and a lot of packages I had brought up from the mail boxes.
The second time was my fault. I thought I heard someone drop something outside my door so I opened the door to look without thinking about her and she bolted past me. When I caught up with her on three, she ran down the stairs to two. When I finally got the elevator to two, she ran down to one, and I had to chase her all over the damned floor. She ran, hid behind a huge carton that was delivered earlier, ran under the staircase and explored, and I hobbled and lurched after her. She's now inside and I've locked the door.
