Our daughter starts school in the fall, so I wanted to start teaching her about money and saving money. I could not have found a cuter way! Not only is the cat adorable, but our daughter is interested in learning. The moving mechanism works well! I have not encountered any problems and we have been using the piggy bank for 2 weeks. However, the sound is rather loud. You can disconnect the speaker, but I am afraid that it will mess up the piggy bank, so I have not tried to. The sound is a screeching sound instead of a meow which our daughter finds to be hilarious. She says, "the cat sounds funny". With this piggy bank, we are mastering the concept of money in a fun way and the whole family enjoys it.
