Case to point: Pet Cosplay.
Making costumes for your pet is a common and generally liked hobby by pet enthusiasts. But to use the word "cosplay" usually brings to mind a mind-boggling marriage between a hobby about wearing costumes of your favorite character, and a creature that generally has a hard time communicating with humans what their favorite is, beyond their familiar comforts such as food, shelter and attention.
Cosplay is about wearing the costume of a character you love and admire.

Going back, I had always hoped that cosplaying would be within the limits of pop-culture and its fandom, normally done inside the confines of a convention. It would help as a reminder that we are there to celebrate one's fandom, that we chose to do so willingly and not forced unto us by higher beings thinking we look cute in them, or its a sure-fire way to win a contest by sacrificing our dignity.
For the record, I'm glad that pets are such forgiving creatures. Either that or very patient ones when it comes to plotting their revenge.
