Claudius is rather scandalized by this method of drinking. While he's definitely a fan of fresh running water, he also believes in maintaining his dignity while doing so, and, he says mournfully, this cat has no shame.
(Don't tell Claudie, but I have a major crush on this cat.)
Edited to add: And it's talk like a pirate day at Library Thing! There's no dignity left in this world! Arrr, mates!
