Poor kitty. There's a video of two young cats one in shallow water and spots a boat, swims out to it to be rescued then was. Then the man in the boat looks back toward the shore or island and sees a sibling starting to swim out so rescues that one, too. He figured somebody dumped them there. So sad.
I hope the photo kitty has an owner who sees or hears about the photo and can claim the cat back. Lots are probably strays though.
