A cat is celebrating Shark Week 2013 by dressing up as a shark and riding around on his iRobot Roomba.

In the latest cat video that has gone viral, Max-Arthur the cat can be seen dressed in the shark suit and bumping into the wall on his iRobot Roomba. . The owner spelled out 'Shark Cat Week' on the tiled floor with sparkly blue glitter, and the cat sits calmly as the Roomba picks up the mess. But the video is posted backwards, so it looks like the Roomba is actually spelling out the words 'Shark Cat Week' instead.

Discovery Channel's shark week kicked off on August 4 and shark lovers have been tuning in to watch the amazing video of the underwater creatures.

Max the cat definitely seems to be a fan of sharks, as he joins others to dress up in a shark costume.

This is not the first time that a video of Max the Roomba cat has gone viral. Last year, a video of Max (dressed in a shark costume) chasing a duckling went viral, garnering nearly 3 million views. Max's pit bull dog friend Sharky is also shown at the end of the video.

Max is a 10-year-old Snowshoe Siamese mix cat. He has over 5,000 likes on Facebook.
