Just for a day this dog can surpass the cat as king of the castle in this Lion dog costume.

I can haz costume? Actually this may be more along the lines of “do not want.” We just assumed that cats really hate dressing up for Halloween and now we have concrete proof that they do. Costume Cats shows off cats in their angriest form, dressed in costume. While we assume that this pictures are the last known photos taken by the owners before their cats viciously attacked them, we get to enjoy the benefit of seeing all of these adorable cats in costumes without having to take the risk of dressing them up ourselves. The site’s got everything from cats in silly hats to cats in full costumes.

If you have a pet and love Star Wars that at some point or another you’ve probably tried this… or you will soon after seeing this gallery. Check out the Yoda bull dog, Princess Leia mini Doberman pinscher and our favorite Darth Vader cat, the scariest evil villain ever. Seriously, there may be nothing more ominous. It seems like most fans stick to the main cast, but we’d love to see a poodle Boba Fett or maybe a Chihuahua Chewbacca. Check out more pets dressed in Star Wars costumes at Screen Junkies.
