Cat Prejudice

There are silent victims in our house. Some are miniature, some are the size of baby dolls, one is even big enough to cause some serious damage if chucked at a window but all are daily targets of my cats. My cats hate My Little Pony. Pink, Purple, Sparkly Rainbow colored, bubble gum scented....oddly enough, they don't discriminate in their prejudice against these poor ponies. They are all attacked, tossed and mauled on a regular basis. These are hard plastic toys but are still dragged and kicked around the room more than a masochistic catnip mouse could ever dream of. I don't understand it and find it a tad bit disturbing. They're such pretty little ponies. What did they ever do to incur such cat disdain?
