Using this water bottle is easy. First, fill it with clean water through the opening and screw on the stainless - steel cap tightly. Then, use the spring - attached hanger to hang the bottle either inside or outside your small pet's wire cage. Make sure it's at a height where your pet can reach the sipper tube comfortably. When it comes to maintenance, clean the bottle regularly to keep the water fresh. You can use warm, soapy water to wash it. Check the sipper tube often to ensure it's not blocked. Also, be careful when handling the glass part to avoid breakage. If you notice any damage, replace the bottle right away to keep your pet safe and hydrated.
