If they make it, someone will buy it. The majority of cat toys are useless. The only things I buy mine are the rabbit-fur mice. Otherwise, a strip of polarfleece from my sewing attached to a stick is great. And how about the basic empty box or paper grocery bag? In all honesty though, I make and sell catnip toys. All of them look like human food, from Christmas cookies and chocolate bunnies to sushi and fortune cookies. Poeple think it looks so cool, especially the sushi, and the holiday items are great for gift giving. No matter what the shape, it all has lots of locally grown catnip inside, and that's all the cat cares about when you get right down to it.
