Using the PetSafe Dancing Dot Laser Cat Toy is easy. You can either place it on a flat, raised surface like a shelf or hang it on a doorknob. This will give the laser wider and faster movement, making the play more exciting for your cat. There are two play modes. If you want a quick play session, choose the One - Time - Play mode, which will run for 15 minutes. If you're going to be away for a while, select the Play - All - Day mode. It will turn on for 15 - minute intervals every 2 hours, up to 6 hours. Remember, the toy needs 3 AAA batteries, but they're not included, so you'll have to buy them separately. The laser is completely safe for your cat as it's a Certified Class 1 laser. After each play session, the toy has a rest mode to prevent your cat from getting over - stimulated. To keep the toy in good condition, make sure to store it in a dry place. Also, check the batteries regularly and replace them when they're low. This way, your cat can keep enjoying the fun for a long time.
