Using your JW Pet InSight Clean Cup is a breeze. First, choose the right size for your bird. Then, use the simple screw - on design to attach the cup to either horizontal or vertical cage bars. Fill it with fresh food or water. When it's time to refill, just remove the cup by twisting and lifting it out of the holder. To keep your cup clean, you can either wash it by hand or put it in the dishwasher as it's dishwasher - safe. Remember that the color of the cup may vary. Always check the cup regularly for any signs of damage, especially if you have a more active bird that might peck at it. And when you clean it, make sure all debris is removed from the clear plastic guard to keep it functioning well.
