Easy! Buy a “cat transformation set” from this site in Japan. The kits include various adornments that you put on your cat’s head to, uh, transform them. For the kit pictured above, the web site offers the following description, translated loosely into English:

It is spring new work! They are chicken transformation goods!

This is a dear chicken transformation set. It is made from the two-tone felt cloth of yellow and orange, and even if it takes, it is finished to the pop impression. Please observe the feather of the chicken currently attached to the both sides of a hat. please imagine a profile when a cat covers it is as dear as it blows off involuntarily — since it can equip with the head volume to which the reed of a chicken also attached hat on a piece of Velcro, attachment and detachment are easy

Sorry the image above is messed up — I’m not sure why the bottom half got cut off. But I really do implore you to go visit that site and read the text and photo captions. I cannot stop laughing.

But what I really want to know is … however did they get that cat in the picture to hold still long enough to attach that thing to its head? My cat Tuna would rip my arm to ribbons if I even thought about trying something like that with her.

(Thanks to boing boing’s guestbar for this one!)
