Last night the Algonquin Hotel hosted their annual Cat Fashion Show for a very good cause: to help raise money for the Mayor's Alliance for NYC's Animals. But the cats participating seemed even more subdued than the audience... and a little uncomfortable in their costumes.

This is the 10th year the Cat Fashion Show has taken place at the Algonquin—where Matilda III the Cat resides—and the theme was: Through the Decades. On hand were Cat Al Hirschfeld, Cat Michael Feinstein, Cat Marilyn Monroe, Cat John Barrymore and... Millennial Cat, who was just wearing a garment with skulls on it, which is really more early-aughts Hot Topic Cat.

Our favorite, however, was the adorable Harpo, who has two different color eyes, and now... our hearts.

Anyway, maybe there just shouldn't be cat fashion shows?
