Query: Amazing!

This toy is simple, as many people have pointed out, but my cat loved it (he passed recently)! My mom (being the "grandmother") kept buying various toys to tempt my cat with no luck. He liked his one little sock and that was it. He didn't even like treats! My mom came over one day with this, and after shrugging my shoulders at how it looked, we put it to the test... Holy cow! He was all over the place with it! As he was 12, he would only run around after it for about 20 minutes and get tired. Whenever he would lie down, we would just bop it towards his front paws and he'd bat it around while lying down! Will be getting another one when I get another cat and will buy my boyfriend one when he gets HIS cat!
