In the top photo, a man awaits the arrival of the yellow water taxi, which arrived a few moments later, and he hopped on. He'll be transported across to the river island you see in the background, where he may have a houseboat, or might just be visiting friends. The cat didn't go with him...
Note the killer icicle in the bottom photo. Though this one doesn't pose any clear danger*, there have been a couple of cases of icicles falling on passers-by downtown.
*Although in the photo it appears likely to fall on boats passing by, the icicle is hanging too close to the deck's outer side to be of any real danger.
