Two Persian cats traveling aboard a Russian tourist ship have gone viral online. 

The fluffy 'captain' and 'sailor' keep watch on the captain’s bridge every night from midnight until 4 am. The feline duo have become celebrities. 'Sailor' has been cruising with the crew since 2008 between Russia’s two main cities.

The average ticket price for the cruise is around 30,000 rubles, or 460 US dollars. The cruise company says the cool cats have definitely brought premiums to the prices. The two Persians get along, although the younger one tends to be a bit more lazy.
