I know it's kinda of a thing in some circles to dress cats in fancy costumes, tiny hats, and generally bling them out. If your into that 
kind of thing and your cat tolerates this great!
 If your cat isn't used dressed up, forcing him/her into a costume is a trip through feline hell. Cats don't just use their eyes to find their way around; they use their ears, noses, paws and even all the fur on their bodies. 
Cats may be predators but they're small, and they know they're prey animals too. you're causing untold stress by decking them out in frog costume, jacket and tie and devil horns. 
Just think about this next time you go to dress up those cute fur-babies.
