Using the PetSafe Peek - a - Bird Electronic Cat Toy is easy. First, decide which mode you want - One - Time - Play for a short play session or Play - All - Day for continuous entertainment. Simply turn the toy on and let your cat enjoy. In Play - All - Day mode, if your cat moves near the toy during the rest period, it will start automatically. When the battery runs low, replace it with a new one. The battery usually lasts about 30 days in Play - All - Day mode. To keep the toy in good condition, clean the feather teasers regularly. If the feathers get dirty or worn out, use the replacement feather. You can also buy additional 4 - pack replacement feathers separately. Keep the toy away from water and sharp objects to avoid damage.
