Australian Grant MacDonald has lived on his yacht, the Osprey, for six years now, but that all ended Wednesday, when The Osprey filled with water and found its way to the bottom of the ocean.

Lucky for MacDonald though, he had a savior in Major Tom.

Major Tom is MacDonald's cat, now touted as a hero by all, which was relentless in waking MacDonald to the impending sinking vessel.

"He kept head-butting me and got me up, and eventually after checking the wind and doing the normal course check I noticed the bow heavy, heavy in the water ... the whole boat was flooded," MacDonald said, according to Xinhuanet.

"It was too dark and too dangerous to enter and try and find a leak. I had to make the quick decision to get the cat and get on the life raft as quickly as possible," he added.

It was hours before a Chinese crew found the pair bobbing in the life raft and rescued them, says People Pets.

"We lifted Major Tom up on a rope, there were massive swells and I had to grab onto the rope ladder and hope for the best, and then the life raft disappeared 10 meters underneath me," he said. If I hadn't been rescued when I had, within four or five hours I would've been washed up on shore and killed, so I was very, very lucky."
