My cats are not very interested in store bought toys. They might bat it around for a while, but they get bored pretty quickly. I've tried buying many things including toy mice and balls that jingle. My orange tabby loves any kind of string, especially shoe laces. He will drag it around the house and put it in different areas. He will then sit by the string and wait for someone to play with him. He does this all day. My gray cat likes anything that makes a crinkly sound, such as plastic and paper. He will bat it around the house and run after it. Sometimes my apartment gets messy because of it lol. They both really love boxes. I ordered them a cat tree from Amazon and at first they like the box it came in more than the tree.
