Have you ever bought a Halloween costume for your cat, put it on the cat and then found that the cat took it off more quickly than you put it on?  To prevent this from happening, try getting a cat collar or harnass with a leash in Halloween decoration patterns.  I found some at http://www.catsandmorestore.com that are very rich in color and pattern.  They have well designed break-away clasps and come in different sizes for a better fit.  If you like them, order yours now for delivery before Halloween.

Here are photos of the ones I saw:
